Paperwork Reduction Act
This document contains new and
modified information collection
requirements. The Commission has
received approval from the Office of
Management and Budget (OMB) for the
information collection requirements
contained in this document, as required
by the Paperwork Reduction Act of
1995, Public Law 104–13. OMB
approval was received on July 17, 2019
for OMB control number 3060–0678. In
addition, we previously sought
comments from the public on how the
Commission might further reduce the
information collection burden for small
business concerns with fewer than 25
employees pursuant to the Small
Business Paperwork Relief Act of 2002,
Public Law 107–198, see 44 U.S.C.

Synopsis
In this Report and Order (R&O), the
Commission simplifies its rules to
facilitate the continued deployment of
Earth Stations in Motion (ESIMs) and

reduce the regulatory burdens on
ESIMs. First, we reorganize and
consolidate the sections in part 25 of the
Commission’s rules, including technical
and operational as well as application
rules, for the three types of FixedSatellite Service (FSS) earth stations
that the Commission authorizes to
transmit while in motion: Earth Stations
on Vessels (ESVs), Vehicle-Mounted
Earth Stations (VMESs), and Earth
Stations Aboard Aircraft (ESAAs),
collectively known as ESIMs. Second,
we amend our rules to allow the
operation of ESIMs in the conventional
Ka-band. Specifically, our rules apply to
ESIMs communicating with
geostationary-orbit (GSO) FSS space
stations operating in 18.3–18.8 GHz and
19.7–20.2 GHz (space-to-Earth), and
28.35–28.6 GHz and 29.25–30.0 GHz
(Earth-to-space) frequency bands. The
new rules create regulatory equity by
adopting a regulatory regime for ESIM
operations in the conventional Ka-band
similar to that which currently exists in
the conventional C-band, the
conventional Ku-band, and in portions
of the extended Ku-band.1
Report and Order
Commenters generally applaud the
Commission for its decision to
consolidate ESIMs regulations into a
single rule section.2 AC BidCo urges the
Commission to implement these
revisions to eliminate redundancy in its
rules and provide a unified framework
1 The ‘‘conventional C-band’’ refers to the 3700–
4200 MHz (space-to-Earth) and 5925–6425 MHz
(Earth-to-space) FSS frequency bands. See 47 CFR
25.103. The ‘‘conventional Ku-band’’ refers to the
11.7–12.2 GHz (space-to-Earth) and 14.0–14.5 GHz
(Earth-to-space) FSS frequency bands, and the
‘‘extended Ku-band’’ refers to the 10.95–11.2 GHz,
11.45–11.7 GHz, and 13.75–14.0 GHz bands.

Federal Register / Vol. 84, No. 195 / Tuesday, October 8, 2019 / Rules and Regulations
for all ESIM operations.3 Many
commenters also support the proposed
technical and operational changes.
Several parties support extending the
routine licensing of ESIMs into the Kaband.4 Iridium, however, expresses
concerns with this proposal,5 which are
addressed below. As discussed in this
decision, we generally adopt many of
the changes proposed in the ESIMS
NPRM.
We proposed to bring all the
technical, operational and coordination
requirements for blanket licensed-ESV,
VMES and ESAA earth stations that are
linked to GSO FSS space stations under
one umbrella rule section, § 25.228,
applicable to ESIMs generally. We
grouped ESIM requirements into the
following categories: (1) Core rules (i.e.
those applicable to all ESIMs); (2)
vehicle-type specific 6 rules that apply
across multiple frequency bands; (3)
frequency-band specific status and
coordination rules; and (4) vehicle-type
specific rules that apply to a single
frequency band. In this Order, we adopt
changes within all of these subparts to
accomplish our goal of simplifying and
streamlining the ESIMs rules.
Following the structure of the ESIMs
NPRM, we first address proposals
involving changes in more than one rule
section and then address proposed
changes in the remaining rules in the
order in which they appear in part 25.
to refer to the type of satellite service in
which the earth station operates, i.e.,
FSS or MSS rather than the type of earth
station, i.e., fixed or mobile.10 Changing
the earth-station categorization in this
definition to FSS and MSS better
reflects the types of stations that can be
licensed to operate anywhere in a
geographic area specified in the license.
Additionally, we adopt other minor
rewording for clarity.
Definition of Network Control and
Monitoring Center (NCMC). We also
adopt the proposed definition of
Network Control and Monitoring Center
in § 25.103.11 An NCMC, as used in the
part 25 rules, is a facility that has the
capability to remotely control earth
stations operating as part of a satellite
network or system.12
Eliminating Cross-References in
Revised Definitions. We revise the
definitions of VMES and ESAA to
eliminate cross-references to rule
sections (§§ 25.226 and 25.227
respectively) that we are deleting in this
Report and Order.13 Similarly, any
cross-references to those deleted
sections elsewhere in the rules are
deleted as well.14 Furthermore, we
revise the definitions of routine
processing and a two-degree compliant
space station in § 25.103 to remove a
cross-reference to § 25.138(a), because
we are consolidating § 25.138(a) into
§ 25.218(i), as explained below.
Definitions
As proposed in the ESIMs NPRM, we
amend several current definitions and
add new definitions to our rules to
provide greater clarity regarding the
operation of earth stations in motion
with GSO FSS space stations.7 In
response to the proposed changes to the
definitions in the NPRM, commenters
uniformly support the changes
discussed below.
Definition of ESIMs. We adopt a
definition for ESIMs in § 25.103.8 ESIM
is defined to mean a term that
collectively designates ESVs, VMESs
and ESAAs, which are already defined
in § 25.103.9
Revised Definition of Blanket License.
We adopt the proposal to change the
definition of Blanket License in § 25.103
Incorporating § 25.138 Into § 25.218,
and Extending the Applicability of
§ 25.218 to the Conventional Ka-Band
and ESIMs
In the ESIMs NPRM, the Commission
proposed moving the conventional Kaband provisions from § 25.138 into
similar paragraphs of § 25.218.15 The
Commission also proposed applying
§ 25.218 to all applications for fixed and
temporary-fixed FSS earth stations
transmitting to geostationary space
stations in the conventional or extended
C-band or Ku-band, or the conventional
Ka-band, and to all applications for

12 As such, an NCMC would constitute a ‘‘remote

rules (see, e.g., 47 CFR 25.271(b), 25.272(d)(1)).
13 The technical and operational rules in
§§ 25.226 and 25.227 are being consolidated in
§ 25.228, and the application rules are being
consolidated in § 25.115. See paras. 0–0 and 67–0

14 While we also moved the §§ 25.221 and 25.222
operating requirements for ESVs under the same
umbrella that covers VMESs and ESAAs (i.e., the
umbrella of the proposed § 25.228 for ESIMs), the
§ 25.103 definition of ESVs does not need to be
revised to eliminate any outdated cross-references
because it does not now contain any crossreferences.

ESIMs in the conventional C-, Ku-, or
Ka-band,16 except for applications
proposing transmission of analog
command signals at a band edge with
bandwidths greater than 1 MHz or
transmission of any other type of analog
signals with bandwidths greater than
200 kHz.17 Section 25.218 contains offaxis equivalent isotropically radiated
power (EIRP) density envelopes for FSS
earth stations transmitting to GSO FSS
space stations in the conventional Cband, extended C-band, conventional
Ku-band, or extended Ku-band.18 Earth
stations in these frequency bands that
comply with these envelopes are
considered ‘‘two-degree-spacing
compliant,’’ and the operators of their
target space stations are not required to
coordinate the operation of these earth
stations with operators of nearby space
stations. As proposed in the NPRM,19
we merge the off-axis EIRP density
provisions of § 25.138 into § 25.218,
thus extending the applicability of
§ 25.218 to conventional Ka-band GSO
FSS earth stations.20 Commenters
support adoption of a consolidated rule
that eliminates duplicative references to
the off-axis EIRP spectral density limits
and that would apply a single set of
limits across all types of FSS earth
station, including those on mobile
platforms.21
Similarly, for organizational
coherence, the Commission proposed
making the conventional Ka-band
requirements in § 25.138(f), which hold
blanket licensees responsible for
operations of transceivers operating
under their license, applicable to earth
station licensees in all frequency
bands.22 We will place this requirement
in new § 25.290,23 and eliminate the
16 See 47 CFR 25.103. The ‘‘extended C-band’’
refers to the 600–3700 MHz (space-to-Earth), 5850–
5925 MHz (Earth-to-space), and 6425–6725 MHz
(Earth-to-space) FSS frequency bands, and the
‘‘conventional Ka-band’’ refers to the 18.3–18.8 GHz
(space-to-Earth), 19.7–20.2 GHz (space-to-Earth),
28.35–28.6 GHz (Earth-to-space), and 29.25–30.0
GHz (Earth-to-space) frequency bands, which the
Commission has designated as primary for GSO FSS
operation. Id.

23 In the NPRM, we proposed placing the
requirements in new § 25.289. See NPRM, 32 FCC
Rcd at 4244 para. 17. Because the Commission
subsequently used § 25.289 to adopt rules governing
the protection of GSO networks by NGSO systems,
we instead adopt these requirements as part of new
§ 25.290.

cross-reference to § 25.138.24 The
Commission proposed that § 25.290
would also include the rule contained
in § 25.287(d), which imposes the same
requirement on licensees of mobile
transmitters or transceivers operating in
some Mobile-Satellite Service
frequencies, allowing that that
§ 25.287(d) be removed.25 Commenters
broadly support these streamlining
reorganizational moves which we
adopt.26
Reorganizing and Streamlining the
Technical, Operational and
Coordination Requirements
Core ESIM Rules
In the ESIMs NPRM, the Commission
sought comment on combining the core
ESIMs rules that were essentially the
same for each type of ESIM.27 As both
Boeing and the Joint Commenters note,
the ‘‘core’’ rules governing ESVs,
VMESs, and ESAAs are nearly but not
quite identical, which creates
unnecessary confusion for applicants
and operators.28 The Commission
proposed to amend the core rules,
where necessary, to create uniformity.
Specifically, for rules related to the
Commission’s GSO FSS two-degree
orbital spacing policy, control of
operating ESIMs, operational reports,
and electromagnetic radiation safety, the
Commission proposed substantive
changes in some cases to eliminate
unnecessary variations across types of
ESIMs.29 As proposed in the NPRM, we
also eliminate unnecessary duplication
of rules across different rule sections.30
These changes are widely applauded by
commenters.31 In the discussion to
follow, we explain the substantive
changes to the following areas of our
ESIM rules: (1) Antenna pointing
accuracy requirements, (2) EIRP density
limits, (3) the self-monitoring (selfdiagnostics) requirement, (4) the
network control and monitoring center
requirement, (5) logging requirements,
and (6) the installation requirements
related to radiation safety.
Antenna Pointing Accuracy
Requirement. As explained in the ESIMs
NPRM, the definition of theta as revised
by the 2015 Second Report and Order

pointing accuracy requirement, because
the limit on off-axis EIRP density
toward adjacent satellites is fixed
regardless of the direction in which the
earth station antenna is pointed.32
Therefore, the Commission proposed to
eliminate the antenna pointing accuracy
requirement contained in the individual
ESV, VMES, and ESAA rules in
§§ 25.221, 25.222, 25.226, and 25.227.33
Most commenters support eliminating
this requirement.34 ViaSat notes that it
is now well-established in the industry
and in the Commission’s precedent that
GSO FSS spectrum resources can be
used for service to mobile platforms
without adversely changing the
operating environment created by a
traditional FSS earth station.35 ViaSat
further states that ‘‘commercially
available pointing mechanisms enable
transmissions from these earth stations
to remain focused on the desired GSO
FSS space station even while the earth
station is mounted on a moving
platform. These technologies have been
proven to be reliable through almost two
decades of successful coexistence.’’ 36
We adopt the proposal to eliminate
the antenna pointing requirement. ESIM
transmissions must remain within our
off-axis EIRP density limits under all
operating conditions. As discussed
32 NPRM, 32 FCC Rcd at 4246, para. 22
(referencing Comprehensive Review of Licensing
and Operating Rules for Satellite Services, IB
Docket No. 12–267, Second Report and Order, 30
FCC Rcd 14713, 14755, para. 115 (2015) (2015
Second Report and Order)). This is the same as the
approach taken by the ITU in Resolution 156
(WRC–15), which prescribes the operating
conditions for ESIMs communicating with FSS
space stations in the 19.7–20.2 GHz and 29.5–30
GHz frequency bands. In that resolution, the off-axis
angle theta is defined as the angle ‘‘from the vector
from the earth station antenna to the associated
satellite.’’ See Final Acts of WRC–15 at 248.
Resolution 156 does not contain any antenna
pointing accuracy requirements, because its off-axis
EIRP density limits, like those in § 25.218 of the
Commission’s rules, are independent of the
direction the ESIM antenna is pointed. See id. at
4246, fn. 33.
33 NPRM, 32 FCC Rcd at 4246, para. 22. As noted
in the NPRM, the definition of theta was revised by
the 2015 Second Report and Order. The definition
in §§ 25.221, 25.222, 25.226, and 25.227 paragraph
(a)(1)(i)(A) formerly read ‘‘theta (q) is the angle in
degrees from the line connecting the focal point of
the antenna to the orbital location of the target
satellite.’’ The minor rewording of the definition
takes into account the fact that not all earth stations
use feedhorn-reflector type antennas with focal
points, and the fact that earth station antennas
pointed toward GSO FSS satellites are usually
pointed to the assigned location of the satellite, and
do not track the actual position of the target satellite
at any given time. The same definition of theta is
now used in § 25.209, 47 CFR 25.209. See id. at
4246, fn. 32.

above,37 these limits are specified at offaxis angles measured with respect to a
vector from the earth station to the
target satellite, not with respect to the
direction the antenna is pointed. Thus,
it is unnecessary for the Commission to
prescribe limits on ESIM antenna
pointing accuracy. By eliminating the
antenna pointing accuracy requirement
but maintaining the off-axis EIRP
density limits, we give ESIM operators
more flexibility in anomalous situations,
because they can meet the off-axis EIRP
density limits either by maintaining
accurate antenna pointing or by
reducing EIRP density when the
antenna is mispointed, while continuing
to protect adjacent-band operations.38
Off-Axis EIRP Density Limits. In the
ESIMs NPRM, the Commission noted
that the off-axis EIRP density limits rule,
§ 25.218, applied to applications for
GSO FSS earth stations at fixed
locations, but specifically excepted
applications for ESVs, VMESs, and
ESAAs.39 However, the numerical EIRP
density limits over each specified
angular range and the definition of q in
§ 25.218 are the same as those for the
same frequency bands in the individual
ESIM §§ 25.221, 25.222, 25.226, and
25.227. Thus, to streamline the ESIMs
rules, we cross-reference the off-axis
EIRP density limits that already exist in
§ 25.218. And because the conventional
Ka-band off-axis EIRP density limits
currently in § 25.138 are merged into
§ 25.218, we only need to crossreference § 25.218 to cover all of the
frequency bands in which our rules
provide for ESIM operations. Most
commenters are in favor of these
changes.40
One commenter, CTIA, expresses
concern that relaxing the off-axis EIRP
density limits may unintentionally limit
the ability for FSS and Upper
Microwave Flexible Use Service
(UMFUS) to coexist.41 CTIA asserts that
knowledge of the precise off-axis EIRP
density from an FSS earth station is a
key component in determining the
interference margin between ESIMs in
the presence of terrestrial operations in
the adjacent spectrum bands.42 CTIA’s
concerns, however, are misplaced since
the Commission is not relaxing the offaxis EIRP density limits for ESIMs.

the individual ESIM sections require

cessation of emissions for ESV, VMES,
and ESAA transmitters based on
detection of antenna mispointing.43
Consistent with the proposed changes
regarding antenna mispointing, the
Commission proposed to replace the
shutdown requirements with provisions
in paragraphs (b) and (c) of § 25.228
requiring cessation or reduction of
emissions in the event that the ESIM or
its associated network control and
monitoring system detects that the ESIM
has exceeded or is about to exceed the
off-axis EIRP density limits.44
Commenters generally support this
proposal, which we adopt.45
Contention Protocols. The
Commission proposed that § 25.228
would not include the requirement in
paragraphs (a)(4) of §§ 25.226 and
25.227 that VMES and ESAA applicants
that plan to use a contention protocol in
the uplink transmissions of their ESIMs
certify that their use of the contention
protocol is reasonable.46 This
requirement is already contained in
§ 25.115(i), and applies by its terms to
applications for ESIMs.47 No
commenters object to this revision,
which is adopted.48
Point of Contact in the United States.
The Commission proposed to
consolidate the requirement that there
be a point of contact in the United
States with the authority and ability to
cease all emissions into the platformspecific rules for ESVs, VMESs, and
ESAAs in § 25.228.49 No commenters
take exception to this proposal, which
we adopt.50
Data Logging Requirement. The
Commission proposed to eliminate the
data logging requirements that are in
paragraphs (a)(5) of §§ 25.221 and
25.222 for C- and Ku-band ESV
operators and in paragraphs (a)(6) of
§§ 25.226 and 25.227 for Ku-band VMES
and ESAA operators.51 The Commission

channel bandwidth, and target satellite
of ESIM transmissions from an ESIM
operator. Commenters almost uniformly
report never having been asked for this
data and were consistent in their
support for eliminating the
requirement.52 For example, Hughes
comments that the Commission should
find that the data logging requirements
imposed on ESIM operators are onerous
and unnecessary and, accordingly,
should be eliminated.53 In its reply
comments, ViaSat notes that HNS, Gogo,
Inmarsat, Kymeta, Intelsat and Boeing
confirm ViaSat’s experience and
understanding that ESIM location
information has been unnecessary
because there does not appear to have
been any suspected cases of
interference.54 However, SES and O3b
state in reply comments that it had used
this data to resolve interference events,
without providing specifics.55 SES and
O3b requests that if the Commission
chooses to eliminate the requirement,
we should remind ESIM operators that
they must cooperate fully to resolve
instances of harmful interference.56
Section 25.274(g) of the Commission’s
rules already imposes this requirement
for all operators.57 Given the experience
with several years of ESIM operations,
we find that the logging requirement is
no longer necessary.
Remote Monitoring and Control
Requirement. The Commission
proposed to incorporate a remote
monitoring and control requirement in
our proposed § 25.228(c), and make it
applicable to all types of ESIMs.58 The
Commission proposed that each remote
terminal must be (1) monitored and
controlled by a network control and
monitoring center (NCMC) or equivalent
facility, (2) that each remote terminal
must comply with ‘‘disable
transmission’’ commands from the
NCMC, and (3) that the NCMC must
monitor the operation of each ESIM
terminal in its network, and transmit a
‘‘disable transmission’’ command to a
remote terminal that malfunctions in
such a way as to cause unacceptable
interference to another
radiocommunication station. These
requirements are spread throughout the

existing rule sections.59 While the
Commission did not include the 100
millisecond response time for
complying with a ‘‘disable
transmission’’ command in the text of
the proposed rules, the Commission did
pose the question as to whether it
should be maintained.60 Commenters
support the proposal to harmonize the
requirements and maintain the 100
millisecond response time.61 For
example, ViaSat notes that the
capability of NCMCs to command
individual ESIMs to cease or reduce
emissions within 100 milliseconds if the
aggregate off-axis EIRP density limits are
being exceeded is already required in
the separate service rules for each type
of ESIM and has not been a barrier to
ESIM deployment.62 Thus, ViaSat says
incorporating a requirement into the
consolidated rule to monitor the
aggregate power density levels of all
ESIMs in the network would not
increase regulatory burdens or
otherwise impede future deployment of
ESIMs.63 To the contrary, ViaSat points
out that this requirement is necessary to
ensure that ESIM networks that use
variable power control are capable of
complying with the off-axis EIRP
density limits in the aggregate, and thus
ensuring that adjacent satellite networks
are adequately protected.64
In contrast, Telesat asserts that
specific NCMC capability requirements
regarding aggregate off-axis EIRP
spectral density limits are unnecessary
and suggests that one possible approach
for network operators to ensure
compliance with aggregate off-axis EIRP
spectral density limits is through the
methodology in ITU Resolution 156.65
Telesat argues that network designers
and operators should decide whether to
monitor aggregate off-axis spectral
density limits, but should not be
required to do so.66
59 The monitoring and control requirements were
in paragraphs (a)(2)(iii) and (a)(3)(iii) of §§ 25.221,
25.222, 25.226, and 25.227; and 25.227(a)(10).

65 Telesat Comments at 7. Telesat states that
under this methodology, compliance with the
aggregate limit would be maintained by limiting the
power density of each individual earth station by
10 log(N) dB, where N is the ‘‘number of earth
stations in motion that are in the receive satellite
beam of the associated satellite and that are
expected to transmit simultaneously on the same
frequency.’’ Id.

Federal Register / Vol. 84, No. 195 / Tuesday, October 8, 2019 / Rules and Regulations
ViaSat asserts that Telesat’s proposal
is flawed due to the fact that Resolution
156 is premised on a requirement that
an NCMC notify individual terminals to
cease operations through ‘‘disable
transmission’’ commands, and that
means individual earth stations must be
controlled by an NCMC in any event.67
According to ViaSat, the mechanism for
controlling individual earth stations to
manage aggregate off-axis EIRP density
still is necessary under Resolution 156,
both to calculate the apportioned power
levels based on the number of operating
terminals and to monitor the aggregate
of the apportioned values, and
command earth stations to adjust their
levels or cease transmitting as
required.’’ 68 We agree with ViaSat and
further note that Note 4 of Annex 1 to
ITU Resolution 156 explicitly addresses
the need of controlling potential
aggregate interference. ViaSat also states
that the 10 log(N) approach, considered
in Note 3 of Annex 1 to ITU Resolution
156 and not requiring controlling
aggregate off-axis EIRP density is
inappropriate for ESIMs using advanced
modulation and coding techniques. We
agree with ViaSat on this point. These
techniques are intended to cope with
propagation impairments specific to the
location of each ESIM or for other
network efficiency considerations. As a
result, such ESIMs may intentionally
transmit with different EIRP density
levels.69 For those reasons, we do not
agree with Telesat’s proposal to
eliminate the need for monitoring the
aggregate off-axis EIRP density.
We also agree with ViaSat, Hughes
and others that retaining the monitoring
and control requirements, consolidating
them into the ESIM section and
harmonizing them for all types of ESIMs
does not increase the regulatory burden.
We also agree with commenters that the
capabilities provided by the NCMC per
these requirements are essential for
effective spectrum sharing. We therefore
adopt the proposed incorporation of the
requirements, including the 100
millisecond response time, into § 25.228
and the application of those
requirements to all types of ESIMs.
Self-Monitoring Requirement. Section
25.227(a)(11) requires that ESAA
terminals be self-monitoring and
capable of automatically ceasing
transmission. § 25.227 paragraphs
(a)(1)(iii), (a)(2)(ii), and (a)(3)(ii), and
corresponding paragraphs in §§ 25.221,
25.222, and 25.226 contain similar selfmonitoring requirements. The
Commission proposed to make this

requirement generally applicable to all
types of ESIMs and to codify it in
§ 25.228(b).70 Commenters are also
supportive of extending this
requirement to all ESIMs in the unified
ESIM rule.71 We adopt the proposal to
codify the self-monitoring requirement
in § 25.228(b).
Cessation of Uplink Transmissions
Upon Loss of Downlink Signal. Sections
25.226(a)(9) and 25.227(a)(9) state that
each VMES or ESAA terminal must
automatically cease transmitting within
5 seconds or 100 milliseconds,
respectively, upon loss of reception of
the satellite downlink signal or when it
detects that unintended satellite
tracking has happened or is about to
happen. In the ESIMs NPRM, the
Commission proposed to eliminate
these rules as redundant 72 because
§ 25.271(g) applies by its terms to all
types of ESIMs, and its provision with
regard to loss of synchronization to
signals from the target satellite is
general enough to cover all situations of
interest. Boeing and other commenters
support this proposal.73 Specifically,
Boeing states that the ‘‘Commission’s
recent adoption of § 25.271(g)
adequately addresses this requirement
for all earth stations operating with FSS
networks without imposing a
potentially arbitrary time limit (i.e., five
[seconds] or a tenth of a second) for
meeting the requirement.’’ 74 We affirm
that § 25.271(g) stands in the place of
these vehicle-specific requirements, and
delete §§ 25.226(a)(9) and 25.227(a)(9).
ESIM Installation Requirement for
Radiation Hazard Mitigation. Our rules
require that all VMES and ESAA
licensees ensure installation of VMES or
ESAA terminals on vehicles by qualified
installers who have an understanding of
the antenna’s radiation environment
and use those measures best suited to
maximize protection of the general
public and persons operating the
vehicle and equipment.75 The
Commission proposed extending this
requirement to ESVs operating in the
C-, Ku- and Ka-bands, because the same
basic rationale for the VMES and ESAA

75 The rules also require that a VMES or ESAA
terminal exhibiting radiation exposure levels
exceeding 1.0 mW/cm2 in accessible areas, such as
at the exterior surface of the radome, must have a
label attached to the surface of the terminal warning
about the radiation hazard and must include
thereon a diagram showing the regions around the
terminal where the radiation levels could exceed
1.0 mW/cm2.

requirement appears to apply equally to
ESVs—i.e., to ensure protection of
members of the public (including those
manning the vessels and operating the
equipment), who may be exposed to
hazardous radiation environments on
vessels as well as on or in the vicinity
of land vehicles and aircraft.76
Accordingly, the Commission proposed
to consolidate the requirement into
paragraph (d) of the proposed
§ 25.228.77 The Commission also
proposed cross-referencing § 1.1310
Table 1 of the Commission’s rules,
rather than specifying the maximum
permitted radiation exposure level in
§ 25.228(d).78 As with other
organizational changes, commenters are
supportive.79 We therefore adopt these
proposals.
Reorganizing and Streamlining
Footnotes to the Table of Frequency
Allocations
In the ESIMs NPRM, we proposed to
reorganize and consolidate the sections
in part 25 of the Commission’s rules,
including technical and operational as
well as application rules, for the three
types of ESIMs. This reorganization
included updates to the Commission’s
Table of Frequency Allocations as
necessary to reflect the changes we
adopt in this Order. We find that this
reorganization can better be
accomplished with a few additional,
non-substantive organizational changes
in the non-Federal Government (NG)

Specifically, we combined the text of
footnote NG55 with part of the text from

5.527A, the resulting footnote is
numbered as NG527A.81 As a result of
combining ESIM-related substantive
issues in the new NG527A, we
additionally move some text in NG52 to
new footnote NG527A. Additionally, we
combine the text of revised footnote
NG180 with the existing text of NG181,
and numbered the resulting footnote as
NG457A.82 Finally, based on these
revisions, we remove footnotes NG55,

Vehicle-Type Specific Rules Applicable
Across Multiple Frequency Bands
ESV Requirements. As explained in
the ESIMs NPRM, there are two rule
sections that address specific
requirements for ESV operators that
were adopted to codify section 306 of
the Communications Act.83 Specifically,
paragraphs (a)(6) and (a)(7) of §§ 25.221
and 25.222 require ESV operators,
licensed by the FCC that are
communicating with ESVs on vessels
registered outside the United States to
maintain detailed information on each
vessel’s country of registry and a point
of contact within the foreign
administration responsible for licensing
the ESV, and to control ESVs using a
hub earth station located in the United
States. However, a U.S.-licensed ESV
may operate under control of a hub
earth station located outside the United
States, provided that the ESV operator
maintains a point of contact in the
United States that can make the ESV
cease transmitting if necessary. Because
paragraphs (a)(6) and (a)(7) of §§ 25.221
and 25.222 are statutorily based, we
retain these requirements in paragraph
(e)(3) and paragraph (e)(1), respectively,
of § 25.228.
We also discontinued our use of the
term ‘‘ESV hub operators’’ and ‘‘hub
earth stations’’ for greater clarity. In
their place, in our revised rules, we use
the term ‘‘network control and
monitoring center’’ (NCMC) 84 to better
reflect the nature of the functions
performed by such facilities.
Commenters generally offer approval of
this ministerial change.85
VMES Requirements. As the
Commission noted in the ESIMs NPRM,
there are currently no rules in part 25
of the Commission’s rules that apply to
VMES terminals in more than one
frequency band,86 because VMES rules
in part 25 only apply to Ku-band
VMESs. In keeping with our goal to
streamline rules for all ESIM operators,
we did not propose in the NPRM, and
do not adopt here, any VMES-specific
rules that would apply across all
frequency bands.
ESAA Requirements. There are four
sections of § 25.227 that are specific to
ESAA operators in the Ku-band. There

are no objections to our proposal to
reorganize these ESAA requirements,
either by eliminating redundant sections
or incorporating them into § 25.228.87
First, § 25.227(a)(12) provides that
ESAA applicants that comply with the
established off-axis EIRP spectraldensity limits may request Permitted
List authority. We adopt the proposal to
eliminate this rule section because this
flexibility is already provided to
applicants by § 25.115(k)(1).88
Next, we adopt the proposal to keep
the requirement that is currently in
§ 25.227(a)(14) and move it into
§ 25.228(g)(2).89 This requirement states
that all ESAA terminals operating in
U.S. airspace, whether on U.S.registered civil aircraft or non-U.S.registered civil aircraft, must be licensed
by the Commission. It further states that
all ESAA terminals on U.S.-registered
civil aircraft operating outside of U.S.
airspace must be licensed by the
Commission, except as provided by
section 303(t) of the Communications
Act.90 We also adopt the proposal to
extend this requirement to apply to all
Ka-band ESAA terminals.
Section 25.227(a)(15) states that for
ESAA systems operating over
international waters, ESAA operators
will certify that their target space station
operators have confirmed that proposed
ESAA operations are within coordinated
parameters for adjacent satellites up to
6 degrees away on the geostationary arc.
In the ESIMs NPRM, the Commission
pointed out that the provisions of
§§ 25.140 and 25.220, which apply to
U.S. satellites and earth stations, and
§ 25.137, which also applies to foreignlicensed points of communication, make
§ 25.227(a)(15) redundant.91 As such,
we eliminate this redundancy deleting
this section and not bringing this
requirement into the ESIM rule section.
Finally, we adopt the proposal to
move the requirements of
§ 25.227(a)(16) to new § 25.228(g)(3),
with a minor revision to make the
requirement clearly imperative.92
Specifically, the provision requires that
prior to operations within the foreign
nation’s airspace, the ESAA operator
must ascertain whether the relevant
administration has operations that could
be affected by ESAA terminals, and
must determine whether that
administration has adopted specific

ESAA operations to the conventional Ka-band is
discussed further in the section on Ka-band ESIM
rules.

requirements concerning ESAA
operations. Further, in moving these
requirements to § 25.228(g)(3), we
extend the existing requirement to apply
to Ka-band ESAA operators. Inmarsat
argues that the provision in paragraph
(g) of § 25.228 that states that an ESAA
terminal in foreign airspace must
operate under the Commission’s rules or
those of the foreign operator, whichever
are more constraining, should be
eliminated.93 We disagree. The
Commission’s rules are designed, inter
alia, to protect adjacent satellites spaced
two degrees apart from interference
from earth stations communicating with
other satellites. In some cases, the
satellites protected from interference by
these rules are U.S.-licensed satellites
serving foreign territory, where the
relevant administrations may not have
comparable rules.
Frequency-Band Specific Status and
Coordination Rules
As proposed in the NPRM and
described in detail below, while moving
the ESIM technical and operational
requirements into a unified rule section,
we eliminate redundancies and
harmonize language whenever possible.
In the separate ESIM sections, there are
frequency-band specific rules for ESVs,
VMESs and ESAAs in the conventional
and extended Ku-bands.94 The
Commission proposed to eliminate
some of these requirements, which were
redundant with other provisions in part
25.95 The specific changes are explained
below. We retain the provisions in
paragraphs (c) and (d) of §§ 25.222,
25.226, and 25.227 which were not
redundant and are now included in
§ 25.228.
Specifically, we eliminate the
provision included in both
§§ 25.226(a)(8) and 25.227(a)(8), because
this provision is redundant with the one
in § 25.209(c)(1). This requirement
provides that in the relevant bands,96
VMES and ESAA terminals receive
protection from interference caused by
space stations other than the target
space station only to the degree to
which harmful interference would not
be expected to be caused to a
hypothetical earth station employing an

the adopted § 25.228, there are
Commission rules for ESIMs operation in four
bands: The conventional C-band and the
conventional and extended Ku-bands and
conventional Ka-band.

(space-to-Earth) and 11.7–12.2 GHz (space-to-Earth)
bands, and ESAA terminal receiving in the 11.7–
12.2 GHz (space-to-Earth) bands do not receive
protection from interference.

antenna conforming to the reference
patterns defined in § 25.209(a) and (b)
and stationary at the location at which
any interference occurred.
Similarly, we eliminate the provision
in §§ 25.222(a)(8), 25.226(a)(7) and
25.227(a)(7), which are redundant with
new footnote NG527A to § 2.106 of the
Commission’s rules.97 This footnote
states that in the 10.95–11.2 GHz (spaceto-Earth) and 11.45–11.7 GHz (space-toEarth) frequency bands ESVs, VMESs
and ESAAs must not claim protection
from transmissions of non-Federal
stations in the fixed service.
Finally, the Commission noted in the
ESIMs NPRM that there are two sets of
coordination requirements for Ku-band
ESIMs, which are contained in
paragraphs (c) and (d) of §§ 25.222,
25.226 and 25.227.98 Paragraphs (c) in
these rule sections address the
coordination requirements related to the
protection of the NASA Tracking and
Data Relay Satellite System (TDRSS) in
the 14.0–14.2 GHz frequency band.
Paragraphs (d) address coordination
requirements designed to protect the
Radio Astronomy Service (RAS) in the
14.47–14.5 GHz frequency band.
Paragraphs (c), as well as paragraphs (d),
in different rule sections, while covering
the same frequency bands and
coordination requirements to protect
TDRSS or RAS operations, as
applicable, are worded slightly
differently in each rule section. We
move these requirements to § 25.228(j),
with non-substantive word changes to
harmonize the language for the
requirements.99

particular to the type of ESIM in a
specific frequency band. For example,
C-band ESVs and Ku-band ESAAs have
requirements that are unique to the
combination of type of earth station and
the particular frequency band in which
it operates. The Commission has never
licensed C-band VMES and ESAA
terminals, and did not propose to adopt
rules for these terminals in this
proceeding.

proposal covered the provisions in
paragraphs (a)(8), (a)(9), (a)(10), (a)(12),
and (a)(13) of § 25.221 as written. No
commenter addressed this proposal, and
we have relocated these provisions to
§ 25.228 without changing the terms, as
proposed.101
As noted in the ESIMs NPRM, rules
were adopted in the 2005 ESV Order to
protect FS and FSS providers in the Cband while providing maximum
flexibility to ESV operators.102
Specifically, Section 25.221(a)(11)
stated that ESVs while in motion do not
receive interference protection from
either terrestrial licensees or satellites.
The Commission proposed to limit this
provision only to terrestrial licensees.
This updated provision is moved to
§ 25.228(h)(4). No commenters object to
the proposal, which we adopt, to amend
the second sentence of Non-Federal
Government footnote NG180 of § 2.106
consistent with this change. As noted
above, this amended footnote is
combined with NG181 and moved to
NG457A for better organization and
consistency.103
Ku-Band ESAA Specific
Requirements. Section 25.227(a)(13)
contains specific requirements for Kuband ESAA providers operating in
international airspace within line-ofsight of the territory of a foreign
administration.104 These requirements
are moved to § 25.228(i), with nonsubstantive word changes to harmonize
the language to that of § 25.228.
Technical and Operational
Requirements for Ka-band ESIMs
The Commission did not propose any
specific technical or operational
requirements for ESVs, VMESs, or
ESAAs operating in the conventional
Ka-band. The Commission stated that
such ESIMs would be authorized subject
to the requirements in § 25.115(n),
which includes the requirement to
comply with the earth station off-axis
EIRP density limits in new § 25.218(i),
unless the ESIM operations are
coordinated under § 25.220.105 This is
similar to the blanket-licensing
provisions for conventional Ka-band
the 3700–4200 MHz portion of the C-band. See

Commission proposed that conventional
Ka-band ESVs would be required to
comply with the requirements in new
§ 25.228(e), conventional Ka-band
VMESs would be required to comply
with the requirement in new § 25.228(f),
and conventional Ka-band ESAAs
would be required to comply with the
requirements in new § 25.228(g). The
Commission sought comment on any
additional provisions that should be
adopted for the operation of ESVs,
VMESs, or ESAAs in the conventional
Ka-band, such as minimum separation
distances to protect the fixed and
mobile services from ESV emissions,
and/or power flux-density limits to
protect the fixed and mobile services
from ESAA emissions.106
The Commission also proposed to
amend an existing footnote to the Table
of Allocations to recognize the operation
of ESIMs as an application of the FSS
with primary status in the conventional
Ka-band.107 The Commission sought
comment on its belief that ESIMs
operating in the conventional Ka-band
in accordance with its proposed rules
would not pose more of a risk of
interference to, nor require more
interference protection from, other
radiocommunication systems than other
earth stations operating in the frequency
band on a primary basis today.108 The
Commission has taken similar steps to
clarify the primary status of C-band and
Ku-band ESIMs.109 Specifically, the
Commission proposed to amend
footnote NG55, which authorizes ESV,
VMES, and ESAA use in the Ku-band,
to include a portion of the Ka-band and
to use the term ‘‘ESIMs.’’ 110 With the

Commission not to authorize ESIMs
operations in the 29.25–29.3 GHz band

addition of ESIM operations with GSO
FSS space stations in this band segment
‘‘would create an impractically complex

MSS feeder link operations.113 Iridium
also argues that the satellite industry
has not developed a method for
determining appropriate exclusion
zones around Iridium feeder-link earth

operations in the band segment will not
cause harmful interference to Iridium
satellite reception of feeder link uplink

GHz band, Inmarsat and ViaSat
provided technical analyses of ESIM
interference into Iridium feeder links
that propose other approaches ESIM
operators could take to coexist with
Iridium in the subject band.116 These
analyses are designed to demonstrate
how ESIMs transmitting in the 29.25–
29.3 GHz band would not exceed the
Iridium feeder link interference
protection criteria even while operating
in the vicinity of Iridium feeder link
earth stations. ViaSat’s analysis
considers six ESAAs operating at
distances of 0 and 100 kilometers from
an Iridium feeder link earth station, and
claims that the carrier-to-interference
ratio of the Iridium feeder link signal is
more than 30 dB for all but 0.0001
percent of the time.117 Inmarsat’s
analysis computes an exclusion zone
around an Iridium feeder link earth
station within which ESIMs would not
be allowed to operate in the 29.25–29.3
GHz band in order to avoid causing
unacceptable interference to Iridium’s
feeder links.118 Iridium challenged the
analyses conducted by ViaSat and
Inmarsat, claiming that some of the
underlying assumptions are incorrect,
and insisted that ESIM operation in the
29.25–29.3 GHz frequency band should
not be allowed.119 In response, ViaSat
refined its analysis referred to in the
Inmarsat and ViaSat Nov. 6 Ex Parte
Letter, and claimed that, even under
more conservative assumptions, no
unacceptable interference would be
caused to Iridium feeder links.120
Similarly, Inmarsat opposed Iridium’s
arguments and insisted that its previous
analysis was valid and even
conservative.121
Subsequently, Iridium argued that the
50 megahertz under discussion between
29.25–29.3 GHz corresponded only to
5% of the total 2,000 megahertz of the
conventional Ka-band spectrum where
ESIM operation would be allowed and

repeated its argument ‘‘that the satellite
industry has been unable to develop a
method for coordinating NGSO feederlinks and ESIMs.’’ 122 In response,
ViaSat argued that channels commonly
used to provide broadband service to
aircraft have bandwidths of 80, 160 or
320 megahertz, and that a prohibition
on using the 50 megahertz in 29.25–29.3
GHz would therefore have a
disproportionate impact on the capacity
of the satellite network.123 In other
words, according to ViaSat, decreasing
the amount of spectrum available from
750 megahertz (in a 29.25–30 GHz band)
to 700 megahertz (in a 29.3–30 GHz
band) would preclude deployment of,
for instance, a network that relies on
two 320 megahertz channels and one 80
megahertz channel. Thus, ViaSat argues,
the impact of not being able to use the
band 29.25–29.3 GHz could be greater
than simply reducing available
spectrum by 50 megahertz, but could
actually prevent providers from making
full use of the conventional Ka-band.
Later filings from Iridium and ViaSat

arguments.124
As an initial matter, coordination is

facility can share with uplinks to GSO

is committed to being as spectrally

that NGSO MSS uplink applicants must
demonstrate that coordination with GSO
FSS operation in the 29.25–29.3 GHz
band is feasible, as required by
paragraph (c) of § 25.258.127 Based on
the record before us, we do not believe
that it is necessary to establish
exclusion zones in order to protect
Iridium space station feeder link
reception. Iridium has previously
acknowledged that the 29.25–29.3 GHz
band is shared with GSO FSS
networks.128 Moreover, in a subsequent
grant modifying Iridium’s license, the
International Bureau clearly restated
Iridium’s co-primary status with respect
to GSO FSS networks.129 Iridium
questions the feasibility of
implementing exclusion zones in which
ESIMs must not operate in the 29.25–
29.3 GHz band as a method of protecting
Iridium feeder links. Instead, we
observe that the current coordination
provisions of § 25.258(a) of our rules
would require ESIM operations in
29.25–29.3 GHz, like those of any other
GSO FSS earth stations operating in the
band, to engage in coordination with
Iridium.130

sufficient interference protection. For
example, ESIMs may seek to protect
Iridium feeder link reception by not
transmitting in the 29.25–29.3 GHz band
when the transmission from the ESIM
would pass through the region in space
in which an Iridium satellite could be
present at an elevation angle of five
degrees or higher 131 as viewed from any
Iridium feeder link earth station
transmitting in the band,132 and such
transmission would exceed the
interference protection criteria of the
Iridium space station feeder link
receiver. An ESIM could calculate when
this would occur if it was programmed
with the location of all of the Iridium
feeder link earth stations in the band.133
More specifically, with this information
programmed into an ESIM, along with
the information and skills that an ESIM
operator already possesses in order to
correctly point its antenna (i.e., its own
location, the location of the target GSO
FSS space station, and the requisite
computing ability), the ESIM operator
could determine with sufficient
precision when to cut off transmissions
in order to comply with these
interference protection criteria.134
131 We choose that elevation angle to be five
degrees or higher as viewed from any Iridium feeder
link earth station transmitting in the band noting
that the Iridium feeder link earth stations in the
29.25–29.3 GHz band are authorized to
communicate with Iridium space stations only
when the Iridium satellites are at an elevation angle
of five degrees or more above the local horizontal
plane, as viewed from the earth station. See, e.g.
Iridium Satellite LLC, IBFS File No. SES–MOD–
20060907–01680 (granted Mar. 29, 2007).
132 The region in space in which an Iridium
satellite could be present at an elevation angle of
five degrees or higher as viewed from a particular
Iridium feeder link earth station is a segment of the
surface of a sphere, or ‘‘cap,’’ at the altitude of the
Iridium satellites, which is approximately 780
kilometers. The size of this cap is such that the arc
length from the point directly above the Iridium
feeder link earth station to the edge of the cap is
approximately 2800 kilometers. The interference
threshold is calculated assuming a worst-case
situation in which the Iridium space station
receiving antenna has maximum gain towards the
ESIM location.
133 This information could be programmed into
the ESIM software and updated as necessary by the
ESIM’s Network Control and Monitoring Center
(NCMC).
134 The calculations could take place in two steps.
The first step would be to identify the point (point
A) at which the direction of an ESIM transmission
capable of causing interference intersects a sphere
that is centered on the center of the Earth and
having a radius equal to the radius of the Earth plus
the altitude of the Iridium satellites. The second
step would be to determine whether the distance
from point A to the point on the same sphere (point
B) that is directly over the Iridium feeder link earth
station is less than approximately 2800 kilometers
in arc length. As mentioned supra, 2800 kilometers
is the arc length from point B to the boundary on
the sphere beyond which the Iridium satellites are
below five degrees elevation angle as viewed from
the feeder link earth station. If the distance between
points A and B is less than 2800 kilometers, the

Moreover, this mechanism responds to
a worst-case Iridium protection
scenario. In a less than worst case
scenario, an ESIM would only need to
avoid transmitting in the 29.25–29.3
GHz band when its transmitted signal
would exceed the Iridium satellite
interference protection criteria at the
actual location of any Iridium satellite
that is within the region in space
described above, which presents more
limited circumstances. If the ESIM
could calculate the precise locations of
the Iridium satellites in real time, rather
than simply the region in space where
the Iridium satellite could be present, it
would only need to avoid transmitting
in the band when its antenna beam
would pass sufficiently near the specific
Iridium satellite location as to interfere
with Iridium satellite reception.135
While this is a more burdensome
calculation for the ESIM to perform and
requires the transmission of information
about the Iridium satellite orbits, it
would afford the ESIM more
opportunities to transmit in the 29.25–
29.3 GHz band than the worst-case
approach described above, if the ESIM
licensee chose to implement it. While
the Commission acknowledges these
potential methods for accomplishing
coordination as plausible options, the
Commission does not specifically
endorse either method, and ESIMs
operators and Iridium are free to explore
other coordination mechanisms.136 If
either ESIM operators or Iridium have
concerns that coordination is not
proceeding in good faith, or fail to come
to an agreement, the matter can be
brought to the attention of the
Commission.
We recognize that coordination
between ESIMs and NGSO space
stations is more complex than
coordination in static situations.
However, as described in the paragraph
above, we are of the view that
coordination is feasible. In addition, any
concerns about aggregate effect for
ESIM emission could interfere with reception of the
Iridium feeder uplink by an Iridium satellite located
at point A.
135 The ESIM operator’s Network Control and
Monitoring Center (NCMC) could periodically
transmit the ephemeris data of the Iridium satellites
to the ESIMs in the network to enable each ESIM
to accurately calculate the locations of the Iridium
satellites. Alternatively, it could transmit other data
describing the Iridium satellite orbits that would
reduce the computational load on the ESIMs.
136 Iridium recommends that the Commission
require ESIMs to comply with this specific
coordination mechanism. Iridium Sept. 12 Ex Parte

interference generated by large numbers
of ESIMs can be addressed during
coordination.137 Finally, we encourage
the parties to act in good faith,
consistent with our overall goal of
promoting efficient use of spectrum.
Iridium asserts that ‘‘coordination
with blanket-licensed fixed terminals
has hardly been common, has been
challenging to the limited extent that it
has occurred, becomes increasingly
complex with each additional system,
and would make sharing with ESIMs
even more difficult.’’ 138 However, the
Commission has already granted blanket
licenses for over five million earth
stations to operate in the 29.25–29.3
GHz band, each of which was required,
pursuant to § 25.258 of our rules, to
coordinate with Iridium.139 These earth
stations are not individually licensed
and can be ubiquitously deployed. We
are not persuaded that the relatively
small increase in total number of earth
stations licensed in the band that we
expect will result from authorizing
ESIM operations will lead to a
significant increase in the use of the
29.25–29.3 GHz band, or will make
coordination exceedingly difficult.140
Moreover, while interference into the
Iridium feeder link receivers depends in
part upon the number of simultaneously
transmitting earth stations in the band,
this number is determined primarily by
the number of uplink spot beams on
each GSO FSS satellite, not by the
number of authorized earth stations.
Thus, we will permit ESIMs to operate
within the FSS in the 29.25–29.3 GHz
band on a co-primary basis, and without
protection zones for MSS feeder link
operations.141
137 With respect to long term interference, only
one ESIM will be transmitting to a satellite receive
beam in the same frequency band and polarization
at any given time. With respect to short term
interference, no ‘‘time aggregation’’ occurs if no
ESIM is allowed to ever exceed the acceptable
interference level associated with small percentages
of time. See also ViaSat Aug. 29 Ex Parte Letter.

140 Compared to the small consumer earth
stations with fixed antennas sold for satellite
broadband access by companies such as Hughes
Network Systems and ViaSat, ESIMs are several
times more expensive, because they need a tracking
antenna, and are therefore unlikely to be deployed
in quantities remotely approaching the quantities in
which those consumer earth stations have been and
will continue to be deployed.
141 Iridium also questions whether ESIMs should
be recognized as an application of the FSS in the
29.25–29.3 GHz band. Iridium Sept. 12 Ex Parte

applications of the FSS (see NG55, NG180, NG 181)
and have been able to do so maintaining the same

With respect to the conditions for
authorizing operations in this band, SES
Americom and its affiliate O3b, ViaSat
and Inmarsat ‘‘recommend that the
Commission adopt a policy statement
acknowledging that it can license ESIM
operations . . . where an ESIM
applicant demonstrates that its
operations will not have a significant
impact on Iridium’s licensed and actual
feeder link operations.’’ 142 We decline
to adopt such an approach, as the
coordination requirement that currently
applies to the operation of fixed earth
stations is also applicable to ESIM
operations. Therefore, as provided
above, ESIM operations in 29.25–29.3
GHz will be subject to coordination with
Iridium, under § 25.258(a) of our rules,
just like those of any other GSO FSS
earth stations operating in the band.143
Because GSO FSS uplinks are coprimary with NGSO MSS feeder link
uplinks in the 29.25–29.3 GHz band, we
expect both Iridium and the licensees of
ESIM operations to coordinate with
each other in good faith.
ESIMs in the 28.35–28.6 GHz Band. In
the NPRM, the Commission also asked
for comment on any possible effects that
these proposed rules may have on
existing or future services in adjacent
frequency bands, such as the UMFUS
operations in the 27.5–28.35 GHz
bands.144 CTIA asserts that the
Commission needs to ensure that
adjacent terrestrial systems are
protected from interference and that we
confirm that ESIM out of band emission
limits are governed by § 25.202(f).145

transmissions in the 28.35–28.6 GHz
band into mobile service (MS) receivers
operating below 28.35 GHz. GSA
analyzed potential interference from
ESIMs into MS receivers for all three
types of ESIMs (VMES, ESV, and ESAA)
for scenarios in which the ESIM is
stationary and in motion, at various
separation distances.146 GSA
acknowledged that some of its
assumptions result in worst-case
interference scenarios.147 GSA
computed both the interference-to-noise
ratio at the MS receivers and the
combined frequency dependent
interference environment created by the operation
of fixed earth stations. Operation of ESIMs in the
band 29.25–29.3 GHz is not any different than the
operation in these other frequency bands.

rejection required by the combined
ESIM transmitters and MS receivers to
mitigate the interference. GSA states its
calculations show that adjacent band
interference above the limits it deems
acceptable would occur in many of the
scenarios it analyzed. In a later
submission, GSA questioned the
modeling used in the ViaSat analysis.148
ViaSat characterized GSA’s analysis
as ‘‘a static analysis that was based on
unrealistic worst-case assumptions and
modeling’’ and claimed that it would be
preferable to rely on ‘‘a statistical
approach including Monte Carlo
simulations and dynamic movement of
stations, both 5G and ESIM, as well as
realistic emission mask data for the
ESIM.’’ 149 According to ViaSat’s
analysis, ‘‘an earth station in motion
(ESIM) operating at the lower end of the
28.35–28.6 GHz band with emissions
complying with the FCC’s 25.202(f) outof-band emissions (OOBE) mask does
not cause unacceptable interference to
5G systems operating at the upper edge
of the adjacent 27.5–28.35 GHz band.’’
ViaSat further states that ‘‘GSA’s
reliance on a deterministic method,
rather than dynamic scenarios, is
contrary to the approach supported by
its own members.’’ 150
We do not express a view here about
the relative merits of a deterministic and
a dynamic approach. However, as noted
above, the Commission has already
blanket-licensed over five million fixed
earth stations in the 28.35–28.6 GHz
band, which can be ubiquitously
deployed at unspecified locations
anywhere within the United States.
ESIMs in this band, like these existing
fixed earth stations will be subject to the
same out-of-band emission limits in
§ 25.202(f) of our rules.151 Despite the
large number of operating fixed earth
stations, no commenter has challenged
the adequacy of these OOBE limits to
protect mobile services from
interference from fixed earth stations.
The number of ESIMs we expect to be
deployed in the 28.35–28.6 GHz band is
a smaller than the number of consumer
earth stations with fixed antennas.
Moreover, as noted above, a single ESIM
will be transmitting to a satellite receive
beam in the same frequency band and

polarization at any given time and
therefore the number of interference
sources that might cause aggregation is
also limited by this fact. GSA has not
made any concrete proposals for out-ofband emission limits specific to ESIMs.
Nor did the Commission propose such
limits. We therefore decline to adopt
any out-of-band emission limits that
would be specifically applicable to
ESIMs at this time. ESIMs must comply
with the out-of-band emission limits
specified in § 25.202(f).
18.6–18.8 GHz Bands. The National
Academy of Sciences, through its
Committee on Radio Frequencies
(CORF), expresses concern that ESIMs
operating in the 18.6–18.8 GHz band
could cause harmful interference to
earth exploration satellite service (EESS)
systems operating around 18.7 GHz.152
CORF suggests that ESIMs might cause
interference to EESS satellite receivers
by transmitting upward toward EESS
satellites in that range.153 CORF also
suggests that the introduction of ESIMs
could lead to increased use of the 18.6–
18.8 GHz band by FSS networks for
downlink transmissions to ESIM
terminals, potentially resulting in
increased reflections of satellite signals
off the surface of the Earth and into
EESS satellite receivers.154 In its reply
comments, Boeing states that it reached
out to CORF representatives to discuss
possible misunderstandings regarding
the nature of operations in the 18.6–18.8
GHz band.155 Specifically, Boeing notes
that given the fact that the 18.3–18.8
GHz band is authorized for downlink
transmissions from FSS satellites, there
is no potential for ESIMs to transmit in
an upward direction in this frequency
segment.156 Second, Boeing pointed out,
that the introduction of ESIMs in the
18.3–18.8 GHz band would not result in
additional satellite downlink
transmissions in this spectrum, it would
just increase the number of fixed and
mobile earth stations that would receive
those signals on Earth.157 Further, as
Boeing states, ‘‘[t]he total number of FSS
networks operating in the Ka-band using
geostationary satellites has been
governed primarily by the number of
space stations that can successfully
operate in a two-degree spacing
environment, not any limits on end user
demand for such capacity.’’ 158 We agree
and will continue to be mindful of the
need to protect the interests of the

passive scientific users of the radio
spectrum, including users of the Radio
Astronomy Service (RAS) and EESS
bands, as observed by CORF.159
CORF further suggests that the
Commission should clarify the proper
meaning of ‘‘radio line of sight.’’ 160
Specifically, CORF states it is
particularly important to note that in
general, the radio and geometric
horizons are different because of
atmospheric refraction.161 Thus, for an
atmosphere having a standard
refractivity gradient, the effective radius
of Earth is about four-thirds that of the
actual radius, which corresponds to
approximately 8,500 km.162 This
increases the radio horizon by about 15
percent compared to the geometric
horizon.163 Although we do not
incorporate a definition of ‘‘radio line of
sight’’ in the rules we adopt here, we
note that CORF’s interpretation of radio
line of sight is widely accepted.
Stratospheric Platforms. The Elefante
Group asks the Commission to ensure
that its stratospheric platforms would be
considered ESAA to enable GSO
satellite communications with its
platforms.164 We note that our ESAA
definition does not set an upper limit on
the altitude of the aircraft
communicating with a geostationary
satellite. In addition, setting such a limit
was not proposed or addressed in this
proceeding. We therefore decline to
generally state that stratospheric
platforms are included in the definition
of ESAA. Proposals for using FSS
frequencies for communications
between such platforms and
geostationary satellites will be examined
taking into consideration their specific
characteristics.
Having addressed the concerns raised
in the record regarding the expansion of
ESIMs to the conventional Ka-band
frequency bands, we find it in the
public interest to adopt rule changes as
proposed in the ESIM NPRM.
Accordingly, we combine footnote
NG55 with the relevant portion of NG52
into NG527A, and state: ‘‘In the bands
11.7–12.2 GHz (space-to-Earth), 14.0–
14.5 GHz (Earth-to-space), 18.3–18.8
GHz (space-to-Earth), 19.7–20.2 GHz
(space-to-Earth), 28.35–28.6 GHz (Earthto-space), and 29.25–30.0 GHz (Earth-tospace), ESIMs may be authorized to

communicate with geostationary
satellites in the fixed-satellite service on
a primary basis.’’ We also amend
§ 25.202(a)(8), (a)(10), and (a)(11)
consistent with these changes to reflect
all frequency bands.165
ESIMs Application Requirements
In the ESIMs NPRM, the Commission
proposed significant reorganization of
the part 25 rules governing all types of
ESIMs. As explained in the ESIMs
NPRM, application requirements for
FSS earth station authorizations at fixed
and temporary-fixed locations are in
§ 25.115. However, the earth station
license application requirements for
ESVs, VMESs, and ESAAs are contained
in paragraph (b) of §§ 25.221, 25.222,
25.226, and 25.227. The Commission
proposed to move the ESIM application
requirements into § 25.115 for better
integration of the rules, and we adopt
this proposal. Specifically, the
application requirements for a particular
frequency band for all types of ESIM
platforms will be contained in
paragraphs (l) (for C-band), (m) (for Kuband), and (n) (for Ka-band) of Section
25.115. This restructuring is globally
supported by the commenters.166
Overview of Earth Station Licensing
Rules. As explained in detail in the
ESIMs NPRM, the part 25 licensing rules
for FSS earth stations transmitting
digital emissions to GSO FSS space
stations provide two main options for
obtaining a license for an earth station
at a fixed location. The first option for
obtaining such a license is to
demonstrate compliance (in one of two
ways) with default limits on emissions
in directions other than toward the
target satellite, which are referred to as
off-axis EIRP density limits.167 These
limits were developed to implement the
Commission’s GSO FSS space station
two-degree orbital spacing policy. They
ensure earth station compatibility with
networks using adjacent satellites in a
two-degree orbital spacing environment
by controlling the level of emissions
from an earth station that can be
transmitted toward adjacent satellite
orbital locations. Under this option,
there are, as indicated, two ways to
show compliance. One alternative is to
demonstrate that the earth station
antenna gain pattern comports with the
off-axis gain limits in § 25.209, and that
the antenna input power density
comports with limits in § 25.212. The

Commission proposed to extend this
option to ESIM applications. The other
alternative, already available to ESIM
applicants, is to demonstrate that the
off-axis EIRP density of the earth station
emissions comports with the applicable
off-axis EIRP density limits in our ESIM
rules.168 The second option to obtain a
license is to demonstrate that the
operations of the earth stations in the
satellite network have been coordinated
with operators of networks using
adjacent satellites that would be affected
by emissions of the earth stations that
exceed the default off-axis EIRP density
limits, under the coordination
requirements of § 25.220.
Commenters support the proposals
that both of these licensing mechanisms
be available to ESIM operators.169
Regarding the alternative of certifying
compliance with the antenna pattern
specifications in § 25.209 and the
antenna input power density
requirements in § 25.212, in addition to
the current option of showing that the
§ 25.218 off-axis EIRP density limits are
met, AC BidCo states that there is
consensus in favor of the Commission’s
plan to give ESIM applicants this
flexibility.170 As explained in more
detail below, we adopt the plan to
continue to make both options for
obtaining a license available for ESIMs
and revise our rules to allow ESIM
applicants to use both alternatives for
showing compliance under the first
option.171 As discussed above,172 we are
eliminating antenna pointing accuracy
requirements for ESIMs. Therefore, the
showings regarding antenna pointing
accuracy in paragraphs (b)(1) of
§§ 25.221, 25.222, 25.226, and 25.227
will no longer be required. Similarly,
the ESIM application showing required
for applicants proposing to meet the 0.2
degree antenna pointing accuracy
requirement in paragraphs (b)(1)(iii) of
§§ 25.221, 25.222, 25.226, and 25.227 is
no longer relevant. Again, because we
are eliminating the antenna pointing
accuracy requirement, the requirement
in the existing ESIM rules that an
applicant proposing to operate with a
maximum pointing error greater than

(b)(1) of §§ 25.221, 25.222, 25.226, and 25.227.

0.2 degrees must declare its maximum
pointing error and show that at the
maximum mispointing, the EIRP density
limits are still met, is no longer
necessary. Once our new rules go into
effect, applicants will have two options
to qualify for a license: Either comply
with the off-axis EIRP density limits,
and provide the information required by
§§ 25.115(l)–(n)(1), or coordinate, and
provide the information required by
§§ 25.115(l)–(n)(2). Additionally, we
eliminate the pointing accuracy
certification requirements of
§§ 25.221(b)(1)(iii), 25.222(b)(1)(iii),
25.226(b)(1)(iii), and 25.227(b)(1)(iii),
subparagraphs (A) and (B). We also
eliminate the maximum mispointing
declaration requirements that were in
paragraphs (b)(1)(iv)(A) and the
cessation of transmissions upon
mispointing demonstration
requirements in paragraphs (b)(1)(iv)(B)
in §§ 25.221, 25.222, 25.226, and 25.227.
We adopt, without commenter
objection, the proposal to retain the
requirement to provide the off-axis EIRP
density showing required by
§§ 25.115(g)(1), and the coordination
certifications required by § 25.220(d),
for applicants that will not meet the offaxis EIRP density limits. Paragraphs
(b)(2), (b)(2)(i) and (b)(2)(ii) of §§ 25.221,
25.222, 25.226, and 25.227 apply to an
applicant proposing to operate with offaxis EIRP density in excess of the levels
in paragraph (a)(1)(i) or (a)(3)(i) of these
sections. Such an applicant will apply
under the provisions in subparagraphs
(a)(2) of § 25.115(l)–(n), which contain
substantially the same requirements for
exhibits to its earth station application.
The Commission further proposed to
allow ESIM applicants the option of
certifying compliance with the antenna
pattern requirements of § 25.209 and the
antenna input power density
requirements of § 25.212, in lieu of the
off-axis EIRP density limits in
§ 25.218.173 This is not a substantive
change, because the off-axis EIRP
density limits in § 25.218, and those
resulting from the summing of the
antenna input power density limits in
§ 25.212 and the antenna off-axis gain
limits in § 25.209 are the same as the
off-axis EIRP density limits in the
individual ESIM §§ 25.221, 25.222,
25.226, and 25.227.174 No commenters

disagree with this proposal.175 For
example, the Joint Commenters note
that giving applicants the option of how
to certify off-axis performance provides
regulatory flexibility without sacrificing
protection from harmful interference.176
Paragraphs (b)(2)(iii) and (b)(2)(iv) of
§§ 25.221, 25.222, 25.226, and 25.227
require detailed showings that each
ESAA transmitter in the system will
automatically cease or reduce emissions
within 100 milliseconds after generating
EIRP density exceeding the applicable
limits. In the rules proposed in the
ESIMs NPRM in § 25.115(l)–(n)(3)(i), the
applicant would have been required to
show how the transmitter will detect
exceedance of the off-axis EIRP density
mask and reduce the power of or shut
down one or more transmitters within
100 milliseconds of receiving a
command to do so from the system’s
network control and monitoring center,
if the aggregate off-axis EIRP spectraldensities of the transmitter or
transmitters exceed the relevant off-axis
EIRP spectral-density limits.
Many commenters argue against the
demonstration requirement in our
proposal. For example, Inmarsat argues
that such demonstration at the
application phase that would produce
the necessary ‘‘detailed showings’’
would be impractical and
burdensome.177 Inmarsat submits that
applicants should be able to certify
compliance in their applications, just
like the requirements of § 25.227.178
Similarly, the Joint Commenters state
they cannot support the proposal, as
written, to include a requirement to
demonstrate how the cessation
requirement will be met.179 Boeing also
states that it concurs with Intelsat and
Inmarsat’s explanation that it would be
appropriate for the Commission to
permit ESIMs applicants to certify that
their earth station terminals will comply
with the Commission’s shut down
requirements to ensure compliance with
the off-axis power spectral density
limits, rather than require a
‘‘demonstration’’ of such compliance.180
Such a certification requirement would
be consistent with the Commission’s
existing rules regarding antenna
pointing and cessation requirements
and therefore should be adopted.181

certification rather than
demonstration.182
After further consideration, we agree
with commenters that a certification is
sufficient for the purposes of this
application requirement. We have used
a certification process elsewhere in our
rules and it has proven effective at
ensuring that licensees satisfy the
technical requirements of our rules.183
Thus, Sections 25.115(l)–(n)(3)(i) will
require all applicants to: ‘‘provide a
certification that the ESIM system is
capable of detecting and automatically
ceasing emissions when an individual
ESIM transmitter exceeds the relevant
off-axis EIRP spectral density limits
specified in § 25.218, or the limits
provided to the target satellite operator
for operation under § 25.220.’’
The certification for a C-band ESV
system in § 25.221(b)(3)(v) regarding
compliance with the power limits in
§ 25.204(h) is eliminated as no longer
necessary. However, we retain a
technical and operational requirement
to meet the power limits in § 25.204(h)
in redesignated § 25.228(h)(7).
As proposed, we note that the
requirements that were in paragraphs
(b)(5) of §§ 25.226 and 25.227 that any
VMES or ESAA applicant filing for a
terminal or system and planning to use
a contention protocol must include in
its application a certification that its
contention protocol use will be
reasonable is substantially the same as
the requirement in § 25.115(i), which we
construe as applying to applications for
ESIMs.184 Therefore, we will not
duplicate the language from
§§ 25.226(b)(5) and 25.227(b)(5) in the
ESIM rules brought into § 25.115.
Further, as proposed, we delete the
requirements that were in paragraphs
(b)(8) of §§ 25.226 and 25.227 that
VMES and ESAA applicants must
submit a radio frequency hazard
analysis determining via calculation,
simulation, or field measurement,
whether ESAA terminals, or classes of
terminals, will produce power densities
that will exceed the Commission’s radio
frequency exposure criteria as
duplicative of § 1.1307(b) of the
Commission’s rules.185 Similarly, we
delete paragraphs (b)(7) of §§ 25.221 and
25.222 and § 25.226(b)(9) as duplicative
of 25.115(k)(1), which we construe as
applicable to ESIM applications.186

Paragraphs (b)(7) of §§ 25.226 and
25.227 require that any VMES or ESAA
applicant must include in its
application a certification that it will
comply with the requirements of
paragraphs (a)(6) of those sections, and
paragraphs (a)(9), (a)(10), and (a)(11) of
§ 25.227. The Commission invited
comment as to whether the certification
requirement serves a useful purpose, or
whether the Commission should
eliminate it, because Commission
licensees are required to comply with
all applicable Commission rules. AC
BidCo comments that ‘‘eliminating this
certification requirement will have no
effect on the substantive technical and
operational standards that an ESIM
operator must meet.’’ 187 Because
licensees will be required to comply
with these provisions even without the
certification requirement, we agree, and
will no longer require such a
certification.
We proposed to remove § 25.226(b)(8),
which states, in part, that all VMES
applicants must demonstrate that their
VMES terminals are capable of
automatically ceasing transmissions
upon the loss of synchronization or
within 5 seconds upon loss of reception
of the satellite downlink signal,
whichever is the shorter timeframe. This
is redundant with § 25.271(g), which
applies by its terms to all transmitting
earth stations. It is not necessary to
duplicate the provisions in § 25.271(g)
in a rule intended specifically for
ESIMs. Additionally, the requirement
for radiation hazard mitigation that had
been included in § 25.226(b)(8) is
incorporated into § 25.228(d), as
explained above.
Finally, as proposed, we retain the
requirements in paragraphs (b)(4) of
§§ 25.221, 25.222, 25.222, 25.226, and

changes to § 25.130(b) are brought into
§ 25.115(a)(6)(i)–(iv), and the Note to
paragraph (g) is now incorporated as a
Note to (a)(10). Further, the Note is
revised to eliminate cross-references to
the individual ESIM §§ 25.221, 25.222,
25.226, and 25.227, and is revised to
cross-reference the appropriate
paragraphs of § 25.115.
Further, the last sentence of
§ 25.130(a) previously stated that
‘‘applicants that are not required to
submit applications on Form 312EZ’’
must submit the information in
subparagraphs (1)–(5) of § 25.130(a) as
an attachment to their applications. The
use of Form 312EZ is not mandatory,
but rather, use is an option available to
applicants under some circumstances.
Therefore, as proposed, we change the
word ‘‘required’’ to ‘‘permitted’’. We
reserve § 25.130. Cross-references to this
section are redirected to the appropriate
paragraphs in § 25.115.
Similarly, we move all requirements
regarding receive-only earth stations,
with minor revisions, from § 25.131 into
§ 25.115(b).192 We reserve § 25.131, and
redirect any cross-references to this
section to the appropriate paragraphs in
§ 25.115.
Other Miscellaneous Changes to
§ 25.115
We adopt the proposals to reorganize
and remove sections that are redundant
or better included elsewhere in the
reorganized sections.193 Specifically, we
incorporate the language regarding
instructions for electronically filing
from § 25.115(a)(4), into § 25.115(a)(1).
We revise the cross-references in
§ 25.115(k)(1) to §§ 25.221, 25.226, and
25.227 to refer instead to the proposed
paragraphs (l)–(n) of § 25.115, consistent
with the unifying of the application
requirements into § 25.115. Similarly,
we adopt non-substantive changes to
§ 25.115(k)(2). The proposed changes to
25.115(c)(1) discussed in the ESIMs
NPRM were previously adopted in the
NGSO FSS Report and Order.194

Federal Register / Vol. 84, No. 195 / Tuesday, October 8, 2019 / Rules and Regulations
Changes Required in Additional
Sections of the Commission’s Rules:
§§ 25.129, 25.133, 25.140, 25.202,
25.204, 25.209, and 25.258 and Notes to
the Table of Frequency Allocations
The Commission proposed several
additional changes in other sections of
part 25 to harmonize the various rule
sections involving ESIMs. We are
updating cross-references to sections
which are being eliminated or
reorganized accordingly. Specifically,
we eliminate references to §§ 25.221,
25.222, 25.226 and 25.227 in
§§ 25.202(a)(8) and 25.140(d)(1). Section
25.140(d)(1) also has an updated
reference to § 25.218. Additionally, we
update the cross-reference to § 25.138(a)
in § 25.140(a)(3)(iii) to point to
§ 25.218(i), which will contain the offaxis EIRP density limits contained in
§ 25.138(a). Similarly, we revise the
cross-reference to § 25.138(a) in
§ 25.258(b) regarding operation of
ubiquitously deployed GSO FSS earth
stations in the 29.25–29.5 GHz
frequency band to point to § 25.218(i).
We are also eliminating cross-references
to §§ 25.221, 25.222, 25.226, and 25.227
in §§ 25.115(g)(1)(iv) and (vii). Further,
we are eliminating cross-references to
§ 25.138, e.g. from §§ 25.115(c)(3)(i)(B),
(c)(3)(ii), and 25.132(d). In § 25.133(d),
the reference to § 25.131 is updated to
reflect the requirement being
reorganized into § 25.115(b).
Because § 25.138 is being removed
and reserved, we remove the reference
to it in § 25.129(c).195 For the same
reasons, we remove references to
§ 25.221 in § 25.140(a)(3)(i), and to
§§ 25.222, 25.226, and 25.227 in
§ 25.140(a)(3)(ii).196 For completeness,
we also note that we eliminate similar
obsolete cross-references in § 25.220(a).
We revise the cross-references to
§§ 25.130 and 25.131 in § 25.209(c)(1) to
reflect the move of the particular
requirements to §§ 25.115(b)(2) and
(b)(4). Similarly, we revise § 25.209(f) to
eliminate the reference to §§ 25.138,
25.221, 25.222, 25.226, and 25.227, and
to refer instead to § 25.218, as well as
other clarifying changes. These changes
are necessary to reflect the changes to
requirements for demonstrations for a
non-conforming antenna. We also

consolidate the requirements in
paragraphs (i)–(k) of § 25.204 into
§ 25.228(j)(2).197
In addition to moving the ESIMrelated sentence of footnote NG52 of the
Table of Frequency Allocations into
NG527A 198 that language in footnote
NG52 is also revised to refer to ESIMs
rather than ESVs, VMESs, and ESAAs to
be consistent with the terminology
adopted in this Report and Order.199
Finally, footnote US133 of the Table of
Frequency Allocation contained crossreferences to sub-paragraphs of
§§ 25.226 and 25.227 that are updated to
point to the appropriate sub-paragraphs
of § 25.228.200

Act, see 5 U.S.C. 801(a)(1)(A).
Procedural Matters
In this document, we have assessed
the effects of reducing the application
burdens of GSO FSS ESIM applicants,
and find that doing so will serve the
public interest and is unlikely to
directly affect businesses with fewer
than 25 employees.

§ 25.228 Operating and coordination
requirements for earth stations in motion
(ESIMs).
(a) ESIM transmissions must comport
with the applicable EIRP density limits
in § 25.218, unless coordinated pursuant
to the requirements in § 25.220.
(b) Each ESIM must be selfmonitoring and, should a condition
occur that would cause the ESIM to
exceed its authorized off-axis EIRP
density limits, the ESIM must
automatically cease transmissions
within 100 milliseconds, and not
resume transmissions until the
condition that caused the ESIM to
exceed those limits is corrected.
(c) Each ESIM must be monitored and
controlled by a network control and
monitoring center (NCMC) or equivalent
facility. Each ESIM must comply with a
‘‘disable transmission’’ command from
the NCMC within 100 milliseconds of
receiving the command. In addition, the
NCMC must monitor the operation of
each ESIM in its network, and transmit
a ‘‘disable transmission’’ command to
any ESIM that operates in such a way
as to exceed the authorized off-axis EIRP
density limit for that ESIM or for all
ESIMs that simultaneously transmit on
the same frequency to the same target
satellite receiving beam. The NCMC
must not allow the ESIM(s) under its
control to resume transmissions until
the condition that caused the ESIM(s) to
exceed the authorized EIRP density
limits is corrected.
(d) ESIM licensees must ensure
installation of ESIM terminals on
vehicles by qualified installers who
have an understanding of the antenna’s
radiation environment and the measures
best suited to maximize protection of
the general public and persons
operating the vehicle and equipment.
An ESIM terminal exhibiting radiation
exposure levels exceeding 1.0 mW/cm2
in accessible areas, such as at the
exterior surface of the radome, must
have a label attached to the surface of
the terminal warning about the radiation
hazard and must include thereon a
diagram showing the regions around the
terminal where the radiation levels
could exceed the maximum radiation
exposure limit specified in 47 CFR
1.1310 Table 1.
(e) The following requirements govern
all ESV operations:
(1) ESV operators must control all
ESVs by a NCMC located in the United
States, except that an ESV on U.S.registered vessels may operate under
control of a NCMC location outside the
United States provided the ESV operator
maintains a point of contact within the
United States that will have the
capability and authority to cause an ESV
VerDate Sep<11>2014

Jkt 250001
on a U.S.-registered vessel to cease
transmitting if necessary.
(2) There must be a point of contact
in the United States, with phone
number and address, available 24 hours
a day, seven days a week, with authority
and ability to cease all emissions from
the ESVs, either directly or through the
facilities of a U.S. NCMC or a NCMC
located in another country with which
the United States has a bilateral
agreement that enables such cessation of
emissions.
(3) ESV NCMC operators
communicating with ESVs on vessels of
foreign registry must maintain detailed
information on each such vessel’s
country of registry and a point of
contact for the relevant administration
responsible for licensing those ESVs.
(f) For all VMES operations, there
must be a point of contact in the United
States, with phone number and address,
available 24 hours a day, seven days a
week, with authority and ability to cease
all emissions from the VMESs.
(g) The following requirements govern
all ESAA operations:
(1) There must be a point of contact
in the United States, with phone
number and address, available 24 hours
a day, seven days a week, with authority
and ability to cease all emissions from
the ESAAs.
(2) All ESAA terminals operated in
U.S. airspace, whether on U.S.registered civil aircraft or non-U.S.registered civil aircraft, must be licensed
by the Commission. All ESAA terminals
on U.S.-registered civil aircraft
operating outside of U.S. airspace must
be licensed by the Commission, except
as provided by section 303(t) of the
Communications Act.
(3) Prior to operations within a foreign
nation’s airspace, the ESAA operator
must ascertain whether the relevant
administration has operations that could
be affected by ESAA terminals, and
must determine whether that
administration has adopted specific
requirements concerning ESAA
operations. When the aircraft enters
foreign airspace, the ESAA terminal
must operate under the Commission’s
rules, or those of the foreign
administration, whichever is more
constraining. To the extent that all
relevant administrations have identified
geographic areas from which ESAA
operations would not affect their radio
operations, ESAA operators may operate
within those identified areas without
further action. To the extent that the
foreign administration has not adopted
requirements regarding ESAA
operations, ESAA operators must
coordinate their operations with any
potentially affected operations.

(h) The following requirements
govern all operations in the 3700–4200
MHz (space-to-Earth) and 5925–6425
MHz (Earth-to-space) frequency bands
of ESVs receiving from or transmitting
to GSO satellites in the Fixed-Satellite
Service:
(1) ESVs must not operate in the
5925–6425 MHz (Earth-to-space) and
3700–4200 MHz (space-to-Earth)
frequency bands on vessels smaller than
300 gross tons.
(2) ESV operators transmitting in the
5925–6425 MHz (Earth-to-space)
frequency band to GSO satellites in the
Fixed-Satellite Service (FSS) must not
seek to coordinate, in any geographic
location, more than 36 megahertz of
uplink bandwidth on each of no more
than two GSO FSS satellites.
(3) ESVs, operating while docked, for
which coordination with terrestrial
stations in the 3700–4200 MHz band is
completed in accordance with § 25.251,
will receive protection from such
terrestrial stations in accordance with
the coordination agreements, for 180
days, renewable for 180 days.
(4) ESVs in motion must not claim
protection from harmful interference
from any authorized terrestrial stations
to which frequencies are already
assigned, or any authorized terrestrial
station to which frequencies may be
assigned in the future in the 3700–4200
MHz (space-to-Earth) frequency band.
(5) ESVs operating within 200 km
from the baseline of the United States,
or within 200 km from a U.S.-licensed
fixed service offshore installation, must
complete coordination with potentially
affected U.S.-licensed fixed service
operators prior to operation. The
coordination method and the
interference criteria objective will be
determined by the frequency
coordinator. The details of the
coordination must be maintained and
available at the frequency coordinator,
and must be filed with the Commission
electronically via the International
Bureau Filing System (https://
licensing.fcc.gov/myibfs/) to be placed
on public notice. The coordination
notifications must be filed in the form
of a statement referencing the relevant
call signs and file numbers. Operation of
each individual ESV may commence
immediately after the public notice that
identifies the notification sent to the
Commission is released. Continuance of
operation of that ESV for the duration of
the coordination term must be
dependent upon successful completion
of the normal public notice process. If,
prior to the end of the 30-day comment
period of the public notice, any
objections are received from U.S.licensed Fixed Service operators that
E:\FR\FM\08OCR1.SGM
08OCR1
53658
Federal Register / Vol. 84, No. 195 / Tuesday, October 8, 2019 / Rules and Regulations
have been excluded from coordination,
the ESV licensee must immediately
cease operation of that particular station
on frequencies used by the affected
U.S.-licensed Fixed Service station until
the coordination dispute is resolved and
the ESV licensee informs the
Commission of the resolution. As used
in this section, ‘‘baseline’’ means the
line from which maritime zones are
measured. The baseline is a
combination of the low-water line and
closing lines across the mouths of
inland water bodies and is defined by a
series of baseline points that include
islands and ‘‘low-water elevations,’’ as
determined by the U.S. Department of
State’s Baseline Committee.
(6) An ESV must automatically cease
transmission if the ESV operates in
violation of the terms of its coordination
agreement, including, but not limited to,
conditions related to speed of the vessel
or if the ESV travels outside the
coordinated area, if within 200 km from
the baseline of the United States, or
within 200 km from a U.S.-licensed
fixed service offshore installation.
Transmissions may be controlled by the
ESV network control and monitoring
center. The frequency coordinator may
decide whether ESV operators should
automatically cease transmissions if the
vessel falls below a prescribed speed
within a prescribed geographic area.
(7) ESV transmissions in the 5925–
6425 MHz (Earth-to-space) band shall
not exceed an EIRP spectral density
towards the radio-horizon of 17 dBW/
MHz, and shall not exceed an EIRP

Where: q is the angle of arrival of the
radio-frequency wave (degrees above the
horizontal) and the aforementioned
limits relate to the pfd under free-space
propagation conditions.
(j) The following requirements govern
all ESIMs transmitting to GSO satellites
in the Fixed-Satellite Service in the
14.0–14.5 GHz band:
(1) Operations of ESIMs in the 14.0–
14.2 GHz (Earth-to-space) frequency
band within 125 km (for ESVs and
VMESs) or within radio line of sight (for
ESAAs) of the NASA TDRSS facilities

New Mexico (latitude 32°20′59″ N,
longitude 106°36′31″ W and latitude
32°32′40″ N, longitude 106°36′48″ W),
or Blossom Point, Maryland (latitude
38°25′44″ N, longitude 77°05′02″ W) are
subject to coordination with the
National Aeronautics and Space
Administration (NASA) through the
National Telecommunications and
Information Administration (NTIA)
Interdepartment Radio Advisory
Committee (IRAC). Licensees must
notify the International Bureau once
they have completed coordination.
Upon receipt of such notification from
a licensee, the International Bureau will
issue a public notice stating that the
licensee may commence operations
within the coordination zone in 30 days
towards the radio-horizon of 20.8 dBW.
The ESV network shall shut-off the ESV
transmitter if either the EIRP spectral
density towards the radio-horizon or the
EIRP towards the radio-horizon is
exceeded.
(i) For ESAA transmissions in the
14.0–14.5 GHz band from international
airspace within line-of-sight of the
territory of a foreign administration
where fixed service networks have
primary allocation in this band, the
maximum power flux density (pfd)
produced at the surface of the Earth by
emissions from a single aircraft carrying
an ESAA terminal must not exceed the
following values unless the foreign
Administration has imposed other
conditions for protecting its fixed
service stations:
dB(W/(m2 · MHz)) ......................................................
dB(W/(m2 · MHz)) ......................................................
if no party has opposed the operations.
When NTIA seeks to provide similar
protection to future TDRSS sites that
have been coordinated through the
IRAC Frequency Assignment
Subcommittee process, NTIA will notify
the Commission’s International Bureau
that the site is nearing operational
status. Upon public notice from the
International Bureau, all Ku-band ESIM
licensees must cease operations in the
14.0–14.2 GHz band within 125 km (for
ESVs and VMESs) or within radio line
of sight (for ESAAs) of the new TDRSS
site until the licensees complete
coordination with NTIA/IRAC for the
new TDRSS facility. Licensees must
notify the International Bureau once
they have completed coordination for
the new TDRSS site. Upon receipt of
such notification from a licensee, the
International Bureau will issue a public
notice stating that the licensee may
commence operations within the
coordination zone in 30 days if no party
has opposed the operations. The ESIM
licensee then will be permitted to
commence operations in the 14.0–14.2
GHz band within 125 km (for ESVs and
VMESs) or within radio line of sight (for
ESAAs) of the new TDRSS site, subject
to any operational constraints
developed in the coordination process.

must submit the coordination agreement
to the Commission. Upon receipt of
such notification from a licensee, the
International Bureau will issue a public

commence operations within the
coordination zone in 30 days if no party
opposed the operations. The ESIMs
licensee then will be permitted to
commence operations in the 14.47–14.5
GHz band within the relevant
coordination distance around the new
RAS site, subject to any operational
constraints developed in the
coordination process.

Paperwork Reduction Act
This document contains new and modified information collection
requirements. The Commission has received approval from the Office of
Management and Budget (OMB) for the information collection requirements
contained in this document, as required by the Paperwork Reduction Act
of 1995, Public Law 104-13. OMB approval was received on July 17, 2019
for OMB control number 3060-0678. In addition, we previously sought
comments from the public on how the Commission might further reduce the
information collection burden for small business concerns with fewer
than 25 employees pursuant to the Small Business Paperwork Relief Act
of 2002, Public Law 107-198, see 44 U.S.C. 3506(c)(4).
Synopsis
In this Report and Order (R&O), the Commission simplifies its rules
to facilitate the continued deployment of Earth Stations in Motion
(ESIMs) and reduce the regulatory burdens on ESIMs. First, we
reorganize and consolidate the sections in part 25 of the Commission's
rules, including technical and operational as well as application
rules, for the three types of Fixed-Satellite Service (FSS) earth
stations that the Commission authorizes to transmit while in motion:
Earth Stations on Vessels (ESVs), Vehicle-Mounted Earth Stations
(VMESs), and Earth Stations Aboard Aircraft (ESAAs), collectively known
as ESIMs. Second, we amend our rules to allow the operation of ESIMs in
the conventional Ka-band. Specifically, our rules apply to ESIMs
communicating with geostationary-orbit (GSO) FSS space stations
operating in 18.3-18.8 GHz and 19.7-20.2 GHz (space-to-Earth), and
28.35-28.6 GHz and 29.25-30.0 GHz (Earth-to-space) frequency bands. The
new rules create regulatory equity by adopting a regulatory regime for
ESIM operations in the conventional Ka-band similar to that which
currently exists in the conventional C-band, the conventional Ku-band,
and in portions of the extended Ku-band.\1\
---------------------------------------------------------------------------
\1\ The ``conventional C-band'' refers to the 3700-4200 MHz
(space-to-Earth) and 5925-6425 MHz (Earth-to-space) FSS frequency
bands. See 47 CFR 25.103. The ``conventional Ku-band'' refers to the
11.7-12.2 GHz (space-to-Earth) and 14.0-14.5 GHz (Earth-to-space)
FSS frequency bands, and the ``extended Ku-band'' refers to the
10.95-11.2 GHz, 11.45-11.7 GHz, and 13.75-14.0 GHz bands.
---------------------------------------------------------------------------
Report and Order
Commenters generally applaud the Commission for its decision to
consolidate ESIMs regulations into a single rule section.\2\ AC BidCo
urges the Commission to implement these revisions to eliminate
redundancy in its rules and provide a unified framework
[[Page 53631]]
for all ESIM operations.\3\ Many commenters also support the proposed
technical and operational changes. Several parties support extending
the routine licensing of ESIMs into the Ka-band.\4\ Iridium, however,
expresses concerns with this proposal,\5\ which are addressed below. As
discussed in this decision, we generally adopt many of the changes
proposed in the ESIMS NPRM.
---------------------------------------------------------------------------
\2\ See, e.g., Boeing Comments at 1; Inmarsat Comments at 8;
Joint Commenters of Kymeta Corporation and Intelsat License LLC
(Joint Comments) at 1; and ViaSat Comments at 1.
\3\ AC BidCo Comments at 2. AC BidCo holds an ESAA license that
is used by its affiliate Gogo Inc to provide inflight connectivity
and wireless entertainment services for commercial and business
fleets around the world. Id. at 1-2.
\4\ See, e.g., Inmarsat Reply Comments at 1.
\5\ Iridium Comments at 12.
---------------------------------------------------------------------------
We proposed to bring all the technical, operational and
coordination requirements for blanket licensed-ESV, VMES and ESAA earth
stations that are linked to GSO FSS space stations under one umbrella
rule section, Sec. 25.228, applicable to ESIMs generally. We grouped
ESIM requirements into the following categories: (1) Core rules (i.e.
those applicable to all ESIMs); (2) vehicle-type specific \6\ rules
that apply across multiple frequency bands; (3) frequency-band specific
status and coordination rules; and (4) vehicle-type specific rules that
apply to a single frequency band. In this Order, we adopt changes
within all of these subparts to accomplish our goal of simplifying and
streamlining the ESIMs rules.
---------------------------------------------------------------------------
\6\ ``Vehicle-type specific'' means applicable only to ESAA, to
ESV, or to VMES.
---------------------------------------------------------------------------
Following the structure of the ESIMs NPRM, we first address
proposals involving changes in more than one rule section and then
address proposed changes in the remaining rules in the order in which
they appear in part 25.
Definitions
As proposed in the ESIMs NPRM, we amend several current definitions
and add new definitions to our rules to provide greater clarity
regarding the operation of earth stations in motion with GSO FSS space
stations.\7\ In response to the proposed changes to the definitions in
the NPRM, commenters uniformly support the changes discussed below.
---------------------------------------------------------------------------
\7\ See NPRM, 32 FCC Rcd at 4242-43, paras. 8-14.
---------------------------------------------------------------------------
Definition of ESIMs. We adopt a definition for ESIMs in Sec.
25.103.\8\ ESIM is defined to mean a term that collectively designates
ESVs, VMESs and ESAAs, which are already defined in Sec. 25.103.\9\
---------------------------------------------------------------------------
\8\ 47 CFR 25.103.
\9\ Id.
---------------------------------------------------------------------------
Revised Definition of Blanket License. We adopt the proposal to
change the definition of Blanket License in Sec. 25.103 to refer to
the type of satellite service in which the earth station operates,
i.e., FSS or MSS rather than the type of earth station, i.e., fixed or
mobile.\10\ Changing the earth-station categorization in this
definition to FSS and MSS better reflects the types of stations that
can be licensed to operate anywhere in a geographic area specified in
the license. Additionally, we adopt other minor rewording for clarity.
---------------------------------------------------------------------------
\10\ NPRM, 32 FCC Rcd at 4242-43, para. 10.
---------------------------------------------------------------------------
Definition of Network Control and Monitoring Center (NCMC). We also
adopt the proposed definition of Network Control and Monitoring Center
in Sec. 25.103.\11\ An NCMC, as used in the part 25 rules, is a
facility that has the capability to remotely control earth stations
operating as part of a satellite network or system.\12\
---------------------------------------------------------------------------
\11\ Id. at 4243, para. 11.
\12\ As such, an NCMC would constitute a ``remote control
point'' as that term is used in the part 25 rules (see, e.g., 47 CFR
25.271(b), 25.272(d)(1)).
---------------------------------------------------------------------------
Eliminating Cross-References in Revised Definitions. We revise the
definitions of VMES and ESAA to eliminate cross-references to rule
sections (Sec. Sec. 25.226 and 25.227 respectively) that we are
deleting in this Report and Order.\13\ Similarly, any cross-references
to those deleted sections elsewhere in the rules are deleted as
well.\14\ Furthermore, we revise the definitions of routine processing
and a two-degree compliant space station in Sec. 25.103 to remove a
cross-reference to Sec. 25.138(a), because we are consolidating Sec.
25.138(a) into Sec. 25.218(i), as explained below.
---------------------------------------------------------------------------
\13\ The technical and operational rules in Sec. Sec. 25.226
and 25.227 are being consolidated in Sec. 25.228, and the
application rules are being consolidated in Sec. 25.115. See paras.
0-0 and 67-0 infra.
\14\ While we also moved the Sec. Sec. 25.221 and 25.222
operating requirements for ESVs under the same umbrella that covers
VMESs and ESAAs (i.e., the umbrella of the proposed Sec. 25.228 for
ESIMs), the Sec. 25.103 definition of ESVs does not need to be
revised to eliminate any outdated cross-references because it does
not now contain any cross-references.
---------------------------------------------------------------------------
Incorporating Sec. 25.138 Into Sec. 25.218, and Extending the
Applicability of Sec. 25.218 to the Conventional Ka-Band and ESIMs
In the ESIMs NPRM, the Commission proposed moving the conventional
Ka-band provisions from Sec. 25.138 into similar paragraphs of Sec.
25.218.\15\ The Commission also proposed applying Sec. 25.218 to all
applications for fixed and temporary-fixed FSS earth stations
transmitting to geostationary space stations in the conventional or
extended C-band or Ku-band, or the conventional Ka-band, and to all
applications for ESIMs in the conventional C-, Ku-, or Ka-band,\16\
except for applications proposing transmission of analog command
signals at a band edge with bandwidths greater than 1 MHz or
transmission of any other type of analog signals with bandwidths
greater than 200 kHz.\17\ Section 25.218 contains off-axis equivalent
isotropically radiated power (EIRP) density envelopes for FSS earth
stations transmitting to GSO FSS space stations in the conventional C-
band, extended C-band, conventional Ku-band, or extended Ku-band.\18\
Earth stations in these frequency bands that comply with these
envelopes are considered ``two-degree-spacing compliant,'' and the
operators of their target space stations are not required to coordinate
the operation of these earth stations with operators of nearby space
stations. As proposed in the NPRM,\19\ we merge the off-axis EIRP
density provisions of Sec. 25.138 into Sec. 25.218, thus extending
the applicability of Sec. 25.218 to conventional Ka-band GSO FSS earth
stations.\20\ Commenters support adoption of a consolidated rule that
eliminates duplicative references to the off-axis EIRP spectral density
limits and that would apply a single set of limits across all types of
FSS earth station, including those on mobile platforms.\21\
---------------------------------------------------------------------------
\15\ NPRM, 32 FCC Rcd at 4243-44, para. 15.
\16\ See 47 CFR 25.103. The ``extended C-band'' refers to the
600-3700 MHz (space-to-Earth), 5850-5925 MHz (Earth-to-space), and
6425-6725 MHz (Earth-to-space) FSS frequency bands, and the
``conventional Ka-band'' refers to the 18.3-18.8 GHz (space-to-
Earth), 19.7-20.2 GHz (space-to-Earth), 28.35-28.6 GHz (Earth-to-
space), and 29.25-30.0 GHz (Earth-to-space) frequency bands, which
the Commission has designated as primary for GSO FSS operation. Id.
\17\ Id. at para. 18.
\18\ We note that the rules do not currently provide for ESIM
operations in the extended C- band.
\19\ NPRM, 32 FCC Rcd at 4243-44, para. 15.
\20\ See 47 CFR 25.218(i). This consolidation of rules does not
involve any change to existing off-axis EIRP spectral density
limits.
\21\ See, e.g., Boeing Comments at 3; Inmarsat Comments at 3;
and ViaSat Comments at 5-6.
---------------------------------------------------------------------------
Similarly, for organizational coherence, the Commission proposed
making the conventional Ka-band requirements in Sec. 25.138(f), which
hold blanket licensees responsible for operations of transceivers
operating under their license, applicable to earth station licensees in
all frequency bands.\22\ We will place this requirement in new Sec.
25.290,\23\ and eliminate the
[[Page 53632]]
cross-reference to Sec. 25.138.\24\ The Commission proposed that Sec.
25.290 would also include the rule contained in Sec. 25.287(d), which
imposes the same requirement on licensees of mobile transmitters or
transceivers operating in some Mobile-Satellite Service frequencies,
allowing that that Sec. 25.287(d) be removed.\25\ Commenters broadly
support these streamlining reorganizational moves which we adopt.\26\
---------------------------------------------------------------------------
\22\ NPRM, 32 FCC Rcd at 4244, para. 17.
\23\ In the NPRM, we proposed placing the requirements in new
Sec. 25.289. See NPRM, 32 FCC Rcd at 4244 para. 17. Because the
Commission subsequently used Sec. 25.289 to adopt rules governing
the protection of GSO networks by NGSO systems, we instead adopt
these requirements as part of new Sec. 25.290.
\24\ 47 CFR 25.290.
\25\ We also proposed to retain the exception for analog video
earth station applications.
\26\ See, e.g., Inmarsat Comments at 3.
---------------------------------------------------------------------------
Reorganizing and Streamlining the Technical, Operational and
Coordination Requirements
Core ESIM Rules
In the ESIMs NPRM, the Commission sought comment on combining the
core ESIMs rules that were essentially the same for each type of
ESIM.\27\ As both Boeing and the Joint Commenters note, the ``core''
rules governing ESVs, VMESs, and ESAAs are nearly but not quite
identical, which creates unnecessary confusion for applicants and
operators.\28\ The Commission proposed to amend the core rules, where
necessary, to create uniformity. Specifically, for rules related to the
Commission's GSO FSS two-degree orbital spacing policy, control of
operating ESIMs, operational reports, and electromagnetic radiation
safety, the Commission proposed substantive changes in some cases to
eliminate unnecessary variations across types of ESIMs.\29\ As proposed
in the NPRM, we also eliminate unnecessary duplication of rules across
different rule sections.\30\ These changes are widely applauded by
commenters.\31\ In the discussion to follow, we explain the substantive
changes to the following areas of our ESIM rules: (1) Antenna pointing
accuracy requirements, (2) EIRP density limits, (3) the self-monitoring
(self-diagnostics) requirement, (4) the network control and monitoring
center requirement, (5) logging requirements, and (6) the installation
requirements related to radiation safety.

---------------------------------------------------------------------------
Antenna Pointing Accuracy Requirement. As explained in the ESIMs
NPRM, the definition of theta as revised by the 2015 Second Report and
Order obviates the need for an antenna pointing accuracy requirement,
because the limit on off-axis EIRP density toward adjacent satellites
is fixed regardless of the direction in which the earth station antenna
is pointed.\32\ Therefore, the Commission proposed to eliminate the
antenna pointing accuracy requirement contained in the individual ESV,
VMES, and ESAA rules in Sec. Sec. 25.221, 25.222, 25.226, and
25.227.\33\ Most commenters support eliminating this requirement.\34\
ViaSat notes that it is now well-established in the industry and in the
Commission's precedent that GSO FSS spectrum resources can be used for
service to mobile platforms without adversely changing the operating
environment created by a traditional FSS earth station.\35\ ViaSat
further states that ``commercially available pointing mechanisms enable
transmissions from these earth stations to remain focused on the
desired GSO FSS space station even while the earth station is mounted
on a moving platform. These technologies have been proven to be
reliable through almost two decades of successful coexistence.'' \36\
---------------------------------------------------------------------------
\32\ NPRM, 32 FCC Rcd at 4246, para. 22 (referencing
Comprehensive Review of Licensing and Operating Rules for Satellite
Services, IB Docket No. 12-267, Second Report and Order, 30 FCC Rcd
14713, 14755, para. 115 (2015) (2015 Second Report and Order)). This
is the same as the approach taken by the ITU in Resolution 156 (WRC-
15), which prescribes the operating conditions for ESIMs
communicating with FSS space stations in the 19.7-20.2 GHz and 29.5-
30 GHz frequency bands. In that resolution, the off-axis angle theta
is defined as the angle ``from the vector from the earth station
antenna to the associated satellite.'' See Final Acts of WRC-15 at
248. Resolution 156 does not contain any antenna pointing accuracy
requirements, because its off-axis EIRP density limits, like those
in Sec. 25.218 of the Commission's rules, are independent of the
direction the ESIM antenna is pointed. See id. at 4246, fn. 33.
\33\ NPRM, 32 FCC Rcd at 4246, para. 22. As noted in the NPRM,
the definition of theta was revised by the 2015 Second Report and
Order. The definition in Sec. Sec. 25.221, 25.222, 25.226, and
25.227 paragraph (a)(1)(i)(A) formerly read ``theta ([thgr]) is the
angle in degrees from the line connecting the focal point of the
antenna to the orbital location of the target satellite.'' The minor
rewording of the definition takes into account the fact that not all
earth stations use feedhorn-reflector type antennas with focal
points, and the fact that earth station antennas pointed toward GSO
FSS satellites are usually pointed to the assigned location of the
satellite, and do not track the actual position of the target
satellite at any given time. The same definition of theta is now
used in Sec. 25.209, 47 CFR 25.209. See id. at 4246, fn. 32.

---------------------------------------------------------------------------
We adopt the proposal to eliminate the antenna pointing
requirement. ESIM transmissions must remain within our off-axis EIRP
density limits under all operating conditions. As discussed above,\37\
these limits are specified at off-axis angles measured with respect to
a vector from the earth station to the target satellite, not with
respect to the direction the antenna is pointed. Thus, it is
unnecessary for the Commission to prescribe limits on ESIM antenna
pointing accuracy. By eliminating the antenna pointing accuracy
requirement but maintaining the off-axis EIRP density limits, we give
ESIM operators more flexibility in anomalous situations, because they
can meet the off-axis EIRP density limits either by maintaining
accurate antenna pointing or by reducing EIRP density when the antenna
is mispointed, while continuing to protect adjacent-band
operations.\38\
---------------------------------------------------------------------------
\37\ See para. 0 and n.9 supra.
\38\ Joint Commenters Comments at 4.
---------------------------------------------------------------------------
Off-Axis EIRP Density Limits. In the ESIMs NPRM, the Commission
noted that the off-axis EIRP density limits rule, Sec. 25.218, applied
to applications for GSO FSS earth stations at fixed locations, but
specifically excepted applications for ESVs, VMESs, and ESAAs.\39\
However, the numerical EIRP density limits over each specified angular
range and the definition of [thgr] in Sec. 25.218 are the same as
those for the same frequency bands in the individual ESIM Sec. Sec.
25.221, 25.222, 25.226, and 25.227. Thus, to streamline the ESIMs
rules, we cross-reference the off-axis EIRP density limits that already
exist in Sec. 25.218. And because the conventional Ka-band off-axis
EIRP density limits currently in Sec. 25.138 are merged into Sec.
25.218, we only need to cross-reference Sec. 25.218 to cover all of
the frequency bands in which our rules provide for ESIM operations.
Most commenters are in favor of these changes.\40\

---------------------------------------------------------------------------
One commenter, CTIA, expresses concern that relaxing the off-axis
EIRP density limits may unintentionally limit the ability for FSS and
Upper Microwave Flexible Use Service (UMFUS) to coexist.\41\ CTIA
asserts that knowledge of the precise off-axis EIRP density from an FSS
earth station is a key component in determining the interference margin
between ESIMs in the presence of terrestrial operations in the adjacent
spectrum bands.\42\ CTIA's concerns, however, are misplaced since the
Commission is not relaxing the off-axis EIRP density limits for ESIMs.

Shutdown Requirements. The shutdown requirements contained in the
individual ESIM sections require
[[Page 53633]]
cessation of emissions for ESV, VMES, and ESAA transmitters based on
detection of antenna mispointing.\43\ Consistent with the proposed
changes regarding antenna mispointing, the Commission proposed to
replace the shutdown requirements with provisions in paragraphs (b) and
(c) of Sec. 25.228 requiring cessation or reduction of emissions in
the event that the ESIM or its associated network control and
monitoring system detects that the ESIM has exceeded or is about to
exceed the off-axis EIRP density limits.\44\ Commenters generally
support this proposal, which we adopt.\45\

Contention Protocols. The Commission proposed that Sec. 25.228
would not include the requirement in paragraphs (a)(4) of Sec. Sec.
25.226 and 25.227 that VMES and ESAA applicants that plan to use a
contention protocol in the uplink transmissions of their ESIMs certify
that their use of the contention protocol is reasonable.\46\ This
requirement is already contained in Sec. 25.115(i), and applies by its
terms to applications for ESIMs.\47\ No commenters object to this
revision, which is adopted.\48\

Point of Contact in the United States. The Commission proposed to
consolidate the requirement that there be a point of contact in the
United States with the authority and ability to cease all emissions
into the platform-specific rules for ESVs, VMESs, and ESAAs in Sec.
25.228.\49\ No commenters take exception to this proposal, which we
adopt.\50\

---------------------------------------------------------------------------
Data Logging Requirement. The Commission proposed to eliminate the
data logging requirements that are in paragraphs (a)(5) of Sec. Sec.
25.221 and 25.222 for C- and Ku-band ESV operators and in paragraphs
(a)(6) of Sec. Sec. 25.226 and 25.227 for Ku-band VMES and ESAA
operators.\51\ The Commission has never requested the logs for the
vehicle location, transmit frequency, channel bandwidth, and target
satellite of ESIM transmissions from an ESIM operator. Commenters
almost uniformly report never having been asked for this data and were
consistent in their support for eliminating the requirement.\52\ For
example, Hughes comments that the Commission should find that the data
logging requirements imposed on ESIM operators are onerous and
unnecessary and, accordingly, should be eliminated.\53\ In its reply
comments, ViaSat notes that HNS, Gogo, Inmarsat, Kymeta, Intelsat and
Boeing confirm ViaSat's experience and understanding that ESIM location
information has been unnecessary because there does not appear to have
been any suspected cases of interference.\54\ However, SES and O3b
state in reply comments that it had used this data to resolve
interference events, without providing specifics.\55\ SES and O3b
requests that if the Commission chooses to eliminate the requirement,
we should remind ESIM operators that they must cooperate fully to
resolve instances of harmful interference.\56\ Section 25.274(g) of the
Commission's rules already imposes this requirement for all
operators.\57\ Given the experience with several years of ESIM
operations, we find that the logging requirement is no longer
necessary.

Remote Monitoring and Control Requirement. The Commission proposed
to incorporate a remote monitoring and control requirement in our
proposed Sec. 25.228(c), and make it applicable to all types of
ESIMs.\58\ The Commission proposed that each remote terminal must be
(1) monitored and controlled by a network control and monitoring center
(NCMC) or equivalent facility, (2) that each remote terminal must
comply with ``disable transmission'' commands from the NCMC, and (3)
that the NCMC must monitor the operation of each ESIM terminal in its
network, and transmit a ``disable transmission'' command to a remote
terminal that malfunctions in such a way as to cause unacceptable
interference to another radiocommunication station. These requirements
are spread throughout the existing rule sections.\59\ While the
Commission did not include the 100 millisecond response time for
complying with a ``disable transmission'' command in the text of the
proposed rules, the Commission did pose the question as to whether it
should be maintained.\60\ Commenters support the proposal to harmonize
the requirements and maintain the 100 millisecond response time.\61\
For example, ViaSat notes that the capability of NCMCs to command
individual ESIMs to cease or reduce emissions within 100 milliseconds
if the aggregate off-axis EIRP density limits are being exceeded is
already required in the separate service rules for each type of ESIM
and has not been a barrier to ESIM deployment.\62\ Thus, ViaSat says
incorporating a requirement into the consolidated rule to monitor the
aggregate power density levels of all ESIMs in the network would not
increase regulatory burdens or otherwise impede future deployment of
ESIMs.\63\ To the contrary, ViaSat points out that this requirement is
necessary to ensure that ESIM networks that use variable power control
are capable of complying with the off-axis EIRP density limits in the
aggregate, and thus ensuring that adjacent satellite networks are
adequately protected.\64\
---------------------------------------------------------------------------
\58\ NPRM, 32 FCC Rcd at 4248-49, para. 31.
\59\ The monitoring and control requirements were in paragraphs
(a)(2)(iii) and (a)(3)(iii) of Sec. Sec. 25.221, 25.222, 25.226,
and 25.227; and 25.227(a)(10).

---------------------------------------------------------------------------
In contrast, Telesat asserts that specific NCMC capability
requirements regarding aggregate off-axis EIRP spectral density limits
are unnecessary and suggests that one possible approach for network
operators to ensure compliance with aggregate off-axis EIRP spectral
density limits is through the methodology in ITU Resolution 156.\65\
Telesat argues that network designers and operators should decide
whether to monitor aggregate off-axis spectral density limits, but
should not be required to do so.\66\
---------------------------------------------------------------------------
\65\ Telesat Comments at 7. Telesat states that under this
methodology, compliance with the aggregate limit would be maintained
by limiting the power density of each individual earth station by 10
log(N) dB, where N is the ``number of earth stations in motion that
are in the receive satellite beam of the associated satellite and
that are expected to transmit simultaneously on the same
frequency.'' Id.
\66\ Id.
---------------------------------------------------------------------------
[[Page 53634]]
ViaSat asserts that Telesat's proposal is flawed due to the fact
that Resolution 156 is premised on a requirement that an NCMC notify
individual terminals to cease operations through ``disable
transmission'' commands, and that means individual earth stations must
be controlled by an NCMC in any event.\67\ According to ViaSat, the
mechanism for controlling individual earth stations to manage aggregate
off-axis EIRP density still is necessary under Resolution 156, both to
calculate the apportioned power levels based on the number of operating
terminals and to monitor the aggregate of the apportioned values, and
command earth stations to adjust their levels or cease transmitting as
required.'' \68\ We agree with ViaSat and further note that Note 4 of
Annex 1 to ITU Resolution 156 explicitly addresses the need of
controlling potential aggregate interference. ViaSat also states that
the 10 log(N) approach, considered in Note 3 of Annex 1 to ITU
Resolution 156 and not requiring controlling aggregate off-axis EIRP
density is inappropriate for ESIMs using advanced modulation and coding
techniques. We agree with ViaSat on this point. These techniques are
intended to cope with propagation impairments specific to the location
of each ESIM or for other network efficiency considerations. As a
result, such ESIMs may intentionally transmit with different EIRP
density levels.\69\ For those reasons, we do not agree with Telesat's
proposal to eliminate the need for monitoring the aggregate off-axis
EIRP density.

We also agree with ViaSat, Hughes and others that retaining the
monitoring and control requirements, consolidating them into the ESIM
section and harmonizing them for all types of ESIMs does not increase
the regulatory burden. We also agree with commenters that the
capabilities provided by the NCMC per these requirements are essential
for effective spectrum sharing. We therefore adopt the proposed
incorporation of the requirements, including the 100 millisecond
response time, into Sec. 25.228 and the application of those
requirements to all types of ESIMs.
Self-Monitoring Requirement. Section 25.227(a)(11) requires that
ESAA terminals be self-monitoring and capable of automatically ceasing
transmission. Sec. 25.227 paragraphs (a)(1)(iii), (a)(2)(ii), and
(a)(3)(ii), and corresponding paragraphs in Sec. Sec. 25.221, 25.222,
and 25.226 contain similar self-monitoring requirements. The Commission
proposed to make this requirement generally applicable to all types of
ESIMs and to codify it in Sec. 25.228(b).\70\ Commenters are also
supportive of extending this requirement to all ESIMs in the unified
ESIM rule.\71\ We adopt the proposal to codify the self-monitoring
requirement in Sec. 25.228(b).

Cessation of Uplink Transmissions Upon Loss of Downlink Signal.
Sections 25.226(a)(9) and 25.227(a)(9) state that each VMES or ESAA
terminal must automatically cease transmitting within 5 seconds or 100
milliseconds, respectively, upon loss of reception of the satellite
downlink signal or when it detects that unintended satellite tracking
has happened or is about to happen. In the ESIMs NPRM, the Commission
proposed to eliminate these rules as redundant \72\ because Sec.
25.271(g) applies by its terms to all types of ESIMs, and its provision
with regard to loss of synchronization to signals from the target
satellite is general enough to cover all situations of interest. Boeing
and other commenters support this proposal.\73\ Specifically, Boeing
states that the ``Commission's recent adoption of Sec. 25.271(g)
adequately addresses this requirement for all earth stations operating
with FSS networks without imposing a potentially arbitrary time limit
(i.e., five [seconds] or a tenth of a second) for meeting the
requirement.'' \74\ We affirm that Sec. 25.271(g) stands in the place
of these vehicle-specific requirements, and delete Sec. Sec.
25.226(a)(9) and 25.227(a)(9).

ESIM Installation Requirement for Radiation Hazard Mitigation. Our
rules require that all VMES and ESAA licensees ensure installation of
VMES or ESAA terminals on vehicles by qualified installers who have an
understanding of the antenna's radiation environment and use those
measures best suited to maximize protection of the general public and
persons operating the vehicle and equipment.\75\ The Commission
proposed extending this requirement to ESVs operating in the C-, Ku-
and Ka-bands, because the same basic rationale for the VMES and ESAA
requirement appears to apply equally to ESVs--i.e., to ensure
protection of members of the public (including those manning the
vessels and operating the equipment), who may be exposed to hazardous
radiation environments on vessels as well as on or in the vicinity of
land vehicles and aircraft.\76\ Accordingly, the Commission proposed to
consolidate the requirement into paragraph (d) of the proposed Sec.
25.228.\77\ The Commission also proposed cross-referencing Sec. 1.1310
Table 1 of the Commission's rules, rather than specifying the maximum
permitted radiation exposure level in Sec. 25.228(d).\78\ As with
other organizational changes, commenters are supportive.\79\ We
therefore adopt these proposals.
---------------------------------------------------------------------------
\75\ The rules also require that a VMES or ESAA terminal
exhibiting radiation exposure levels exceeding 1.0 mW/cm\2\ in
accessible areas, such as at the exterior surface of the radome,
must have a label attached to the surface of the terminal warning
about the radiation hazard and must include thereon a diagram
showing the regions around the terminal where the radiation levels
could exceed 1.0 mW/cm\2\.

Reorganizing and Streamlining Footnotes to the Table of Frequency
Allocations
In the ESIMs NPRM, we proposed to reorganize and consolidate the
sections in part 25 of the Commission's rules, including technical and
operational as well as application rules, for the three types of ESIMs.
This reorganization included updates to the Commission's Table of
Frequency Allocations as necessary to reflect the changes we adopt in
this Order. We find that this reorganization can better be accomplished
with a few additional, non-substantive organizational changes in the
non-Federal Government (NG) Footnotes to the Table of Frequency
Allocations.\80\
---------------------------------------------------------------------------
\80\ 47 CFR 2.106. We note that these revisions are in addition
to the changes proposed in the NPRM, such as to US133, and are
adopted herein.
---------------------------------------------------------------------------
Specifically, we combined the text of footnote NG55 with part of
the text from footnote NG52 which addresses ESIM sub-bands. Based on
the number of the international footnote for ESIMs, 5.527A, the
resulting footnote is numbered as NG527A.\81\ As a result of combining
ESIM-related substantive issues in the new NG527A, we additionally move
some text in NG52 to new footnote NG527A. Additionally, we combine the
text of revised footnote NG180 with the existing text of NG181, and
numbered the resulting footnote as NG457A.\82\ Finally, based on these
revisions, we remove footnotes NG55, NG180, and NG181. The substantive
[[Page 53635]]
content in those footnotes is fully covered by the other revisions. We
note below where these changes impact other revisions.
---------------------------------------------------------------------------
\81\ See Appendix B--Final Rules.
\82\ As with the new ESIM footnote, NG527A, the numbering for
the ESV footnote, NG457A, is based on the number of the
international footnote for ESVs in the 5925-6425 MHz band, 5.457A.
---------------------------------------------------------------------------
Vehicle-Type Specific Rules Applicable Across Multiple Frequency Bands
ESV Requirements. As explained in the ESIMs NPRM, there are two
rule sections that address specific requirements for ESV operators that
were adopted to codify section 306 of the Communications Act.\83\
Specifically, paragraphs (a)(6) and (a)(7) of Sec. Sec. 25.221 and
25.222 require ESV operators, licensed by the FCC that are
communicating with ESVs on vessels registered outside the United States
to maintain detailed information on each vessel's country of registry
and a point of contact within the foreign administration responsible
for licensing the ESV, and to control ESVs using a hub earth station
located in the United States. However, a U.S.-licensed ESV may operate
under control of a hub earth station located outside the United States,
provided that the ESV operator maintains a point of contact in the
United States that can make the ESV cease transmitting if necessary.
Because paragraphs (a)(6) and (a)(7) of Sec. Sec. 25.221 and 25.222
are statutorily based, we retain these requirements in paragraph (e)(3)
and paragraph (e)(1), respectively, of Sec. 25.228.
---------------------------------------------------------------------------
\83\ NPRM, 32 FCC Rcd at 4250, para. 36. See also 47 U.S.C. 306.
---------------------------------------------------------------------------
We also discontinued our use of the term ``ESV hub operators'' and
``hub earth stations'' for greater clarity. In their place, in our
revised rules, we use the term ``network control and monitoring
center'' (NCMC) \84\ to better reflect the nature of the functions
performed by such facilities. Commenters generally offer approval of
this ministerial change.\85\
---------------------------------------------------------------------------
\84\ As noted in paragraph 0 supra, we adopt the definition of
network control and monitoring center (NCMC) in Sec. 25.103.
\85\ Inmarsat Comments at 6.
---------------------------------------------------------------------------
VMES Requirements. As the Commission noted in the ESIMs NPRM, there
are currently no rules in part 25 of the Commission's rules that apply
to VMES terminals in more than one frequency band,\86\ because VMES
rules in part 25 only apply to Ku-band VMESs. In keeping with our goal
to streamline rules for all ESIM operators, we did not propose in the
NPRM, and do not adopt here, any VMES-specific rules that would apply
across all frequency bands.
---------------------------------------------------------------------------
\86\ NPRM, 32 FCC Rcd at 4250, para. 39.
---------------------------------------------------------------------------
ESAA Requirements. There are four sections of Sec. 25.227 that are
specific to ESAA operators in the Ku-band. There are no objections to
our proposal to reorganize these ESAA requirements, either by
eliminating redundant sections or incorporating them into Sec.
25.228.\87\
---------------------------------------------------------------------------
\87\ Our decision to extend the requirements for ESAA operations
to the conventional Ka-band is discussed further in the section on
Ka-band ESIM rules.
---------------------------------------------------------------------------
First, Sec. 25.227(a)(12) provides that ESAA applicants that
comply with the established off-axis EIRP spectral-density limits may
request Permitted List authority. We adopt the proposal to eliminate
this rule section because this flexibility is already provided to
applicants by Sec. 25.115(k)(1).\88\
---------------------------------------------------------------------------
\88\ NPRM, 32 FCC Rcd at 4250, para. 40.
---------------------------------------------------------------------------
Next, we adopt the proposal to keep the requirement that is
currently in Sec. 25.227(a)(14) and move it into Sec.
25.228(g)(2).\89\ This requirement states that all ESAA terminals
operating in U.S. airspace, whether on U.S.-registered civil aircraft
or non-U.S.-registered civil aircraft, must be licensed by the
Commission. It further states that all ESAA terminals on U.S.-
registered civil aircraft operating outside of U.S. airspace must be
licensed by the Commission, except as provided by section 303(t) of the
Communications Act.\90\ We also adopt the proposal to extend this
requirement to apply to all Ka-band ESAA terminals.
---------------------------------------------------------------------------
\89\ NPRM, 32 FCC Rcd at 4250-51, para. 41.
\90\ 47 U.S.C. 303(t).
---------------------------------------------------------------------------
Section 25.227(a)(15) states that for ESAA systems operating over
international waters, ESAA operators will certify that their target
space station operators have confirmed that proposed ESAA operations
are within coordinated parameters for adjacent satellites up to 6
degrees away on the geostationary arc. In the ESIMs NPRM, the
Commission pointed out that the provisions of Sec. Sec. 25.140 and
25.220, which apply to U.S. satellites and earth stations, and Sec.
25.137, which also applies to foreign-licensed points of communication,
make Sec. 25.227(a)(15) redundant.\91\ As such, we eliminate this
redundancy deleting this section and not bringing this requirement into
the ESIM rule section.
---------------------------------------------------------------------------
\91\ NPRM, 32 FCC Rcd at 4251, para. 42.
---------------------------------------------------------------------------
Finally, we adopt the proposal to move the requirements of Sec.
25.227(a)(16) to new Sec. 25.228(g)(3), with a minor revision to make
the requirement clearly imperative.\92\ Specifically, the provision
requires that prior to operations within the foreign nation's airspace,
the ESAA operator must ascertain whether the relevant administration
has operations that could be affected by ESAA terminals, and must
determine whether that administration has adopted specific requirements
concerning ESAA operations. Further, in moving these requirements to
Sec. 25.228(g)(3), we extend the existing requirement to apply to Ka-
band ESAA operators. Inmarsat argues that the provision in paragraph
(g) of Sec. 25.228 that states that an ESAA terminal in foreign
airspace must operate under the Commission's rules or those of the
foreign operator, whichever are more constraining, should be
eliminated.\93\ We disagree. The Commission's rules are designed, inter
alia, to protect adjacent satellites spaced two degrees apart from
interference from earth stations communicating with other satellites.
In some cases, the satellites protected from interference by these
rules are U.S.-licensed satellites serving foreign territory, where the
relevant administrations may not have comparable rules.

---------------------------------------------------------------------------
Frequency-Band Specific Status and Coordination Rules
As proposed in the NPRM and described in detail below, while moving
the ESIM technical and operational requirements into a unified rule
section, we eliminate redundancies and harmonize language whenever
possible. In the separate ESIM sections, there are frequency-band
specific rules for ESVs, VMESs and ESAAs in the conventional and
extended Ku-bands.\94\ The Commission proposed to eliminate some of
these requirements, which were redundant with other provisions in part
25.\95\ The specific changes are explained below. We retain the
provisions in paragraphs (c) and (d) of Sec. Sec. 25.222, 25.226, and
25.227 which were not redundant and are now included in Sec. 25.228.
---------------------------------------------------------------------------
\94\ Under the adopted Sec. 25.228, there are Commission rules
for ESIMs operation in four bands: The conventional C-band and the
conventional and extended Ku-bands and conventional Ka-band.
\95\ NPRM, 32 FCC Rcd at 4251, para. 44.
---------------------------------------------------------------------------
Specifically, we eliminate the provision included in both
Sec. Sec. 25.226(a)(8) and 25.227(a)(8), because this provision is
redundant with the one in Sec. 25.209(c)(1). This requirement provides
that in the relevant bands,\96\ VMES and ESAA terminals receive
protection from interference caused by space stations other than the
target space station only to the degree to which harmful interference
would not be expected to be caused to a hypothetical earth station
employing an
[[Page 53636]]
antenna conforming to the reference patterns defined in Sec. 25.209(a)
and (b) and stationary at the location at which any interference
occurred.
---------------------------------------------------------------------------
\96\ Specifically, VMES terminal receiving in the 10.95-11.2 GHz
(space-to-Earth), 11.45-11.7 GHz (space-to-Earth) and 11.7-12.2 GHz
(space-to-Earth) bands, and ESAA terminal receiving in the 11.7-12.2
GHz (space-to-Earth) bands do not receive protection from
interference.
---------------------------------------------------------------------------
Similarly, we eliminate the provision in Sec. Sec. 25.222(a)(8),
25.226(a)(7) and 25.227(a)(7), which are redundant with new footnote
NG527A to Sec. 2.106 of the Commission's rules.\97\ This footnote
states that in the 10.95-11.2 GHz (space-to-Earth) and 11.45-11.7 GHz
(space-to-Earth) frequency bands ESVs, VMESs and ESAAs must not claim
protection from transmissions of non-Federal stations in the fixed
service.
---------------------------------------------------------------------------
\97\ As noted above, we are moving the relevant text to NG527A
from NG52 for organizational purposes.
---------------------------------------------------------------------------
Finally, the Commission noted in the ESIMs NPRM that there are two
sets of coordination requirements for Ku-band ESIMs, which are
contained in paragraphs (c) and (d) of Sec. Sec. 25.222, 25.226 and
25.227.\98\ Paragraphs (c) in these rule sections address the
coordination requirements related to the protection of the NASA
Tracking and Data Relay Satellite System (TDRSS) in the 14.0-14.2 GHz
frequency band. Paragraphs (d) address coordination requirements
designed to protect the Radio Astronomy Service (RAS) in the 14.47-14.5
GHz frequency band. Paragraphs (c), as well as paragraphs (d), in
different rule sections, while covering the same frequency bands and
coordination requirements to protect TDRSS or RAS operations, as
applicable, are worded slightly differently in each rule section. We
move these requirements to Sec. 25.228(j), with non-substantive word
changes to harmonize the language for the requirements.\99\

---------------------------------------------------------------------------
Vehicle-Type Specific Rules Applicable to a Single Frequency Band
Part 25 includes rules that are particular to the type of ESIM in a
specific frequency band. For example, C-band ESVs and Ku-band ESAAs
have requirements that are unique to the combination of type of earth
station and the particular frequency band in which it operates. The
Commission has never licensed C-band VMES and ESAA terminals, and did
not propose to adopt rules for these terminals in this proceeding.
C-band ESV Specific Requirements. The Commission proposed to retain
and move several requirements that are unique to ESVs operating in the
C-band to Sec. 25.228(h).\100\ Specifically, this proposal covered the
provisions in paragraphs (a)(8), (a)(9), (a)(10), (a)(12), and (a)(13)
of Sec. 25.221 as written. No commenter addressed this proposal, and
we have relocated these provisions to Sec. 25.228 without changing the
terms, as proposed.\101\
---------------------------------------------------------------------------
\100\ NPRM, 32 FCC Rcd at 4252-53, para. 49-50. The Commission
has an open proceeding exploring additional uses of ``mid-band
spectrum,'' including the 3700-4200 MHz portion of the C-band. See
Expanding Flexible Use in Mid-Band Spectrum Between 3.7 and 24 GHz,
Notice of Inquiry, 32 FCC Rcd 6373 (2017); Expanding Flexible Use of
the 3.7-4.2 GHz Band, Order and Notice of Proposed Rulemaking, FCC
18-91 (rel. July 13, 2018) (Mid-band Proceeding). Operation of ESIMs
will be subject to any changes to the Commission's rules made as a
result of Commission action in the Mid-Band Proceeding.
\101\ Section 25.228(h).
---------------------------------------------------------------------------
As noted in the ESIMs NPRM, rules were adopted in the 2005 ESV
Order to protect FS and FSS providers in the C-band while providing
maximum flexibility to ESV operators.\102\ Specifically, Section
25.221(a)(11) stated that ESVs while in motion do not receive
interference protection from either terrestrial licensees or
satellites. The Commission proposed to limit this provision only to
terrestrial licensees. This updated provision is moved to Sec.
25.228(h)(4). No commenters object to the proposal, which we adopt, to
amend the second sentence of Non-Federal Government footnote NG180 of
Sec. 2.106 consistent with this change. As noted above, this amended
footnote is combined with NG181 and moved to NG457A for better

Technical and Operational Requirements for Ka-band ESIMs
The Commission did not propose any specific technical or
operational requirements for ESVs, VMESs, or ESAAs operating in the
conventional Ka-band. The Commission stated that such ESIMs would be
authorized subject to the requirements in Sec. 25.115(n), which
includes the requirement to comply with the earth station off-axis EIRP
density limits in new Sec. 25.218(i), unless the ESIM operations are
coordinated under Sec. 25.220.\105\ This is similar to the blanket-
licensing provisions for conventional Ka-band earth stations in Sec.
25.138. The Commission proposed that conventional Ka-band ESVs would be
required to comply with the requirements in new Sec. 25.228(e),
conventional Ka-band VMESs would be required to comply with the
requirement in new Sec. 25.228(f), and conventional Ka-band ESAAs
would be required to comply with the requirements in new Sec.
25.228(g). The Commission sought comment on any additional provisions
that should be adopted for the operation of ESVs, VMESs, or ESAAs in
the conventional Ka-band, such as minimum separation distances to
protect the fixed and mobile services from ESV emissions, and/or power
flux-density limits to protect the fixed and mobile services from ESAA
emissions.\106\

The Commission also proposed to amend an existing footnote to the
Table of Allocations to recognize the operation of ESIMs as an
application of the FSS with primary status in the conventional Ka-
band.\107\ The Commission sought comment on its belief that ESIMs
operating in the conventional Ka-band in accordance with its proposed
rules would not pose more of a risk of interference to, nor require
more interference protection from, other radiocommunication systems
than other earth stations operating in the frequency band on a primary
basis today.\108\ The Commission has taken similar steps to clarify the
primary status of C-band and Ku-band ESIMs.\109\ Specifically, the
Commission proposed to amend footnote NG55, which authorizes ESV, VMES,
and ESAA use in the Ku-band, to include a portion of the Ka-band and to
use the term ``ESIMs.'' \110\ With the exception of the areas discussed
below in the bands, 18.6-18.8 GHz, 29.25-29.3 GHz and 28.35-28.6,
commenters generally supported these proposed changes.
---------------------------------------------------------------------------
\107\ NPRM, 32 FCC Rcd at 4253, para. 53.
\108\ As stated in the NPRM, the Commission already blanket
licenses ubiquitously-deployed fixed earth stations in the
conventional Ka-band under Sec. 25.138; under the proposed rules
ESIMs would have to comply with regulations designed to ensure that
they do not cause more interference than fixed earth stations. Id.

29.25-29.3 GHz Band. In the 29.25-29.5 GHz band, GSO FSS operations
and feeder links for the NGSO Mobile Satellite Service (MSS systems)
are designated for co-primary usage. Iridium operates feeder links for
its NGSO MSS system in the 29.1-29.3
[[Page 53637]]
GHz band.\111\ Iridium urges the Commission not to authorize ESIMs
operations in the 29.25-29.3 GHz band that is shared with Iridium
feeder links.\112\ Iridium claims that the addition of ESIM operations
with GSO FSS space stations in this band segment ``would create an
impractically complex sharing environment'' with its NGSO-MSS feeder
link operations.\113\ Iridium also argues that the satellite industry
has not developed a method for determining appropriate exclusion zones
around Iridium feeder-link earth stations, outside of which ESIM
operations in the band segment will not cause harmful interference to
Iridium satellite reception of feeder link uplink transmissions.\114\
Iridium has three such feeder-link earth stations in the United States
that are currently authorized to operate in the 29.25-29.3 GHz band:
One in Tempe, Arizona; one in Fairbanks, Alaska; and one in Wahiawa,
Hawaii.\115\

In response to Iridium's proposal to bar ESIM operations in the
29.25-29.3 GHz band, Inmarsat and ViaSat provided technical analyses of
ESIM interference into Iridium feeder links that propose other
approaches ESIM operators could take to coexist with Iridium in the
subject band.\116\ These analyses are designed to demonstrate how ESIMs
transmitting in the 29.25-29.3 GHz band would not exceed the Iridium
feeder link interference protection criteria even while operating in
the vicinity of Iridium feeder link earth stations. ViaSat's analysis
considers six ESAAs operating at distances of 0 and 100 kilometers from
an Iridium feeder link earth station, and claims that the carrier-to-
interference ratio of the Iridium feeder link signal is more than 30 dB
for all but 0.0001 percent of the time.\117\ Inmarsat's analysis
computes an exclusion zone around an Iridium feeder link earth station
within which ESIMs would not be allowed to operate in the 29.25-29.3
GHz band in order to avoid causing unacceptable interference to
Iridium's feeder links.\118\ Iridium challenged the analyses conducted
by ViaSat and Inmarsat, claiming that some of the underlying
assumptions are incorrect, and insisted that ESIM operation in the
29.25-29.3 GHz frequency band should not be allowed.\119\ In response,
ViaSat refined its analysis referred to in the Inmarsat and ViaSat Nov.
6 Ex Parte Letter, and claimed that, even under more conservative
assumptions, no unacceptable interference would be caused to Iridium
feeder links.\120\ Similarly, Inmarsat opposed Iridium's arguments and
insisted that its previous analysis was valid and even
conservative.\121\

Subsequently, Iridium argued that the 50 megahertz under discussion
between 29.25-29.3 GHz corresponded only to 5% of the total 2,000
megahertz of the conventional Ka-band spectrum where ESIM operation
would be allowed and repeated its argument ``that the satellite
industry has been unable to develop a method for coordinating NGSO
feeder-links and ESIMs.'' \122\ In response, ViaSat argued that
channels commonly used to provide broadband service to aircraft have
bandwidths of 80, 160 or 320 megahertz, and that a prohibition on using
the 50 megahertz in 29.25-29.3 GHz would therefore have a
disproportionate impact on the capacity of the satellite network.\123\
In other words, according to ViaSat, decreasing the amount of spectrum
available from 750 megahertz (in a 29.25-30 GHz band) to 700 megahertz
(in a 29.3-30 GHz band) would preclude deployment of, for instance, a
network that relies on two 320 megahertz channels and one 80 megahertz
channel. Thus, ViaSat argues, the impact of not being able to use the
band 29.25-29.3 GHz could be greater than simply reducing available
spectrum by 50 megahertz, but could actually prevent providers from
making full use of the conventional Ka-band. Later filings from Iridium
and ViaSat further elaborated on their prior arguments.\124\

---------------------------------------------------------------------------
As an initial matter, coordination is required between GSO FSS and
feeder links to MSS space stations that have co-primary status in the
frequency band 29.25-29.3 GHz.\125\ The Commission has previously
stated that NGSO MSS applicants bear the burden of showing
[[Page 53638]]
that a new NGSO MSS feeder-link facility can share with uplinks to GSO
FSS space stations.\126\ The Commission is committed to being as
spectrally efficient as possible, and has stressed that NGSO MSS uplink
applicants must demonstrate that coordination with GSO FSS operation in
the 29.25-29.3 GHz band is feasible, as required by paragraph (c) of
Sec. 25.258.\127\ Based on the record before us, we do not believe
that it is necessary to establish exclusion zones in order to protect
Iridium space station feeder link reception. Iridium has previously
acknowledged that the 29.25-29.3 GHz band is shared with GSO FSS
networks.\128\ Moreover, in a subsequent grant modifying Iridium's
license, the International Bureau clearly restated Iridium's co-primary
status with respect to GSO FSS networks.\129\ Iridium questions the
feasibility of implementing exclusion zones in which ESIMs must not
operate in the 29.25-29.3 GHz band as a method of protecting Iridium
feeder links. Instead, we observe that the current coordination
provisions of Sec. 25.258(a) of our rules would require ESIM
operations in 29.25-29.3 GHz, like those of any other GSO FSS earth
stations operating in the band, to engage in coordination with
Iridium.\130\
---------------------------------------------------------------------------
\125\ While allocation of a given frequency band to a particular
service on a ``primary'' basis entitles that service to protection
against harmful interference from stations of a ``secondary''
service, ``co-primary'' services such as the NGSO MSS and GSO FSS in
the 29.25-29.5 GHz band share that band on an equal basis and may
not cause harmful interference to each other. See 47 CFR 2.104(d),
2.105(c).

\130\ See also 47 CFR 25.203(h).
---------------------------------------------------------------------------
We find that coordination under Sec. 25.258(a) will provide
Iridium with sufficient interference protection. For example, ESIMs may
seek to protect Iridium feeder link reception by not transmitting in
the 29.25-29.3 GHz band when the transmission from the ESIM would pass
through the region in space in which an Iridium satellite could be
present at an elevation angle of five degrees or higher \131\ as viewed
from any Iridium feeder link earth station transmitting in the
band,\132\ and such transmission would exceed the interference
protection criteria of the Iridium space station feeder link receiver.
An ESIM could calculate when this would occur if it was programmed with
the location of all of the Iridium feeder link earth stations in the
band.\133\ More specifically, with this information programmed into an
ESIM, along with the information and skills that an ESIM operator
already possesses in order to correctly point its antenna (i.e., its
own location, the location of the target GSO FSS space station, and the
requisite computing ability), the ESIM operator could determine with
sufficient precision when to cut off transmissions in order to comply
with these interference protection criteria.\134\ Moreover, this
mechanism responds to a worst-case Iridium protection scenario. In a
less than worst case scenario, an ESIM would only need to avoid
transmitting in the 29.25-29.3 GHz band when its transmitted signal
would exceed the Iridium satellite interference protection criteria at
the actual location of any Iridium satellite that is within the region
in space described above, which presents more limited circumstances. If
the ESIM could calculate the precise locations of the Iridium
satellites in real time, rather than simply the region in space where
the Iridium satellite could be present, it would only need to avoid
transmitting in the band when its antenna beam would pass sufficiently
near the specific Iridium satellite location as to interfere with
Iridium satellite reception.\135\ While this is a more burdensome
calculation for the ESIM to perform and requires the transmission of
information about the Iridium satellite orbits, it would afford the
ESIM more opportunities to transmit in the 29.25-29.3 GHz band than the
worst-case approach described above, if the ESIM licensee chose to
implement it. While the Commission acknowledges these potential methods
for accomplishing coordination as plausible options, the Commission
does not specifically endorse either method, and ESIMs operators and
Iridium are free to explore other coordination mechanisms.\136\ If
either ESIM operators or Iridium have concerns that coordination is not
proceeding in good faith, or fail to come to an agreement, the matter
can be brought to the attention of the Commission.
---------------------------------------------------------------------------
\131\ We choose that elevation angle to be five degrees or
higher as viewed from any Iridium feeder link earth station
transmitting in the band noting that the Iridium feeder link earth
stations in the 29.25-29.3 GHz band are authorized to communicate
with Iridium space stations only when the Iridium satellites are at
an elevation angle of five degrees or more above the local
horizontal plane, as viewed from the earth station. See, e.g.
Iridium Satellite LLC, IBFS File No. SES-MOD-20060907-01680 (granted
Mar. 29, 2007).
\132\ The region in space in which an Iridium satellite could be
present at an elevation angle of five degrees or higher as viewed
from a particular Iridium feeder link earth station is a segment of
the surface of a sphere, or ``cap,'' at the altitude of the Iridium
satellites, which is approximately 780 kilometers. The size of this
cap is such that the arc length from the point directly above the
Iridium feeder link earth station to the edge of the cap is
approximately 2800 kilometers. The interference threshold is
calculated assuming a worst-case situation in which the Iridium
space station receiving antenna has maximum gain towards the ESIM
location.
\133\ This information could be programmed into the ESIM
software and updated as necessary by the ESIM's Network Control and
Monitoring Center (NCMC).
\134\ The calculations could take place in two steps. The first
step would be to identify the point (point A) at which the direction
of an ESIM transmission capable of causing interference intersects a
sphere that is centered on the center of the Earth and having a
radius equal to the radius of the Earth plus the altitude of the
Iridium satellites. The second step would be to determine whether
the distance from point A to the point on the same sphere (point B)
that is directly over the Iridium feeder link earth station is less
than approximately 2800 kilometers in arc length. As mentioned
supra, 2800 kilometers is the arc length from point B to the
boundary on the sphere beyond which the Iridium satellites are below
five degrees elevation angle as viewed from the feeder link earth
station. If the distance between points A and B is less than 2800
kilometers, the ESIM emission could interfere with reception of the
Iridium feeder uplink by an Iridium satellite located at point A.
\135\ The ESIM operator's Network Control and Monitoring Center
(NCMC) could periodically transmit the ephemeris data of the Iridium
satellites to the ESIMs in the network to enable each ESIM to
accurately calculate the locations of the Iridium satellites.
Alternatively, it could transmit other data describing the Iridium
satellite orbits that would reduce the computational load on the
ESIMs.
\136\ Iridium recommends that the Commission require ESIMs to
comply with this specific coordination mechanism. Iridium Sept. 12
Ex Parte Letters at 2; Sept. 18 Javed Ex Parte Letter at 2, and
Iridium Sept. 20 Bender Ex Parte Letter at 2. While Inmarsat, ViaSat
and SES, urge the Commission to maintain flexibility with respect to
possible coordination mechanisms. ESIM Operators Sept. 18 Joint Ex
Parte Letter at 3. See also ViaSat Sept. 21 Ex Parte Letter.
---------------------------------------------------------------------------
We recognize that coordination between ESIMs and NGSO space
stations is more complex than coordination in static situations.
However, as described in the paragraph above, we are of the view that
coordination is feasible. In addition, any concerns about aggregate
effect for
[[Page 53639]]
interference generated by large numbers of ESIMs can be addressed
during coordination.\137\ Finally, we encourage the parties to act in
good faith, consistent with our overall goal of promoting efficient use
of spectrum.
---------------------------------------------------------------------------
\137\ With respect to long term interference, only one ESIM will
be transmitting to a satellite receive beam in the same frequency
band and polarization at any given time. With respect to short term
interference, no ``time aggregation'' occurs if no ESIM is allowed
to ever exceed the acceptable interference level associated with
small percentages of time. See also ViaSat Aug. 29 Ex Parte Letter.
---------------------------------------------------------------------------
Iridium asserts that ``coordination with blanket-licensed fixed
terminals has hardly been common, has been challenging to the limited
extent that it has occurred, becomes increasingly complex with each
additional system, and would make sharing with ESIMs even more
difficult.'' \138\ However, the Commission has already granted blanket
licenses for over five million earth stations to operate in the 29.25-
29.3 GHz band, each of which was required, pursuant to Sec. 25.258 of
our rules, to coordinate with Iridium.\139\ These earth stations are
not individually licensed and can be ubiquitously deployed. We are not
persuaded that the relatively small increase in total number of earth
stations licensed in the band that we expect will result from
authorizing ESIM operations will lead to a significant increase in the
use of the 29.25-29.3 GHz band, or will make coordination exceedingly
difficult.\140\ Moreover, while interference into the Iridium feeder
link receivers depends in part upon the number of simultaneously
transmitting earth stations in the band, this number is determined
primarily by the number of uplink spot beams on each GSO FSS satellite,
not by the number of authorized earth stations. Thus, we will permit
ESIMs to operate within the FSS in the 29.25-29.3 GHz band on a co-
primary basis, and without protection zones for MSS feeder link
operations.\141\

\138\ Iridium Sept. 25, 2017 Ex Parte Letter at 2.
\139\ See, e.g., HNS License Sub, LLC, Satellite Policy Branch
Information: Action Taken, Public Notice, Report No. SAT-00905 (rel.
Feb. 28, 2007) (IBFS File No. SES-LIC-20061226-02232).
\140\ Compared to the small consumer earth stations with fixed
antennas sold for satellite broadband access by companies such as
Hughes Network Systems and ViaSat, ESIMs are several times more
expensive, because they need a tracking antenna, and are therefore
unlikely to be deployed in quantities remotely approaching the
quantities in which those consumer earth stations have been and will
continue to be deployed.
\141\ Iridium also questions whether ESIMs should be recognized
as an application of the FSS in the 29.25-29.3 GHz band. Iridium
Sept. 12 Ex Parte Letter at 3 and Iridium Sept. 12 Bender Ex Parte
Letter at 3. ESIMs are currently operating in several frequency
bands where they have been treated as applications of the FSS (see
NG55, NG180, NG 181) and have been able to do so maintaining the
same interference environment created by the operation of fixed
earth stations. Operation of ESIMs in the band 29.25-29.3 GHz is not
any different than the operation in these other frequency bands.
---------------------------------------------------------------------------
With respect to the conditions for authorizing operations in this
band, SES Americom and its affiliate O3b, ViaSat and Inmarsat
``recommend that the Commission adopt a policy statement acknowledging
that it can license ESIM operations . . . where an ESIM applicant
demonstrates that its operations will not have a significant impact on
Iridium's licensed and actual feeder link operations.'' \142\ We
decline to adopt such an approach, as the coordination requirement that
currently applies to the operation of fixed earth stations is also
applicable to ESIM operations. Therefore, as provided above, ESIM
operations in 29.25-29.3 GHz will be subject to coordination with
Iridium, under Sec. 25.258(a) of our rules, just like those of any
other GSO FSS earth stations operating in the band.\143\ Because GSO
FSS uplinks are co-primary with NGSO MSS feeder link uplinks in the
29.25-29.3 GHz band, we expect both Iridium and the licensees of ESIM
operations to coordinate with each other in good faith.

ESIMs in the 28.35-28.6 GHz Band. In the NPRM, the Commission also
asked for comment on any possible effects that these proposed rules may
have on existing or future services in adjacent frequency bands, such
as the UMFUS operations in the 27.5-28.35 GHz bands.\144\ CTIA asserts
that the Commission needs to ensure that adjacent terrestrial systems
are protected from interference and that we confirm that ESIM out of
band emission limits are governed by Sec. 25.202(f).\145\ The Global
Mobile Suppliers Association (GSA) presented an analyses of
interference caused by ESIM transmissions in the 28.35-28.6 GHz band
into mobile service (MS) receivers operating below 28.35 GHz. GSA
analyzed potential interference from ESIMs into MS receivers for all
three types of ESIMs (VMES, ESV, and ESAA) for scenarios in which the
ESIM is stationary and in motion, at various separation distances.\146\
GSA acknowledged that some of its assumptions result in worst-case
interference scenarios.\147\ GSA computed both the interference-to-
noise ratio at the MS receivers and the combined frequency dependent
rejection required by the combined ESIM transmitters and MS receivers
to mitigate the interference. GSA states its calculations show that
adjacent band interference above the limits it deems acceptable would
occur in many of the scenarios it analyzed. In a later submission, GSA
questioned the modeling used in the ViaSat analysis.\148\

ViaSat characterized GSA's analysis as ``a static analysis that was
based on unrealistic worst-case assumptions and modeling'' and claimed
that it would be preferable to rely on ``a statistical approach
including Monte Carlo simulations and dynamic movement of stations,
both 5G and ESIM, as well as realistic emission mask data for the
ESIM.'' \149\ According to ViaSat's analysis, ``an earth station in
motion (ESIM) operating at the lower end of the 28.35-28.6 GHz band
with emissions complying with the FCC's 25.202(f) out-of-band emissions
(OOBE) mask does not cause unacceptable interference to 5G systems
operating at the upper edge of the adjacent 27.5-28.35 GHz band.''
ViaSat further states that ``GSA's reliance on a deterministic method,
rather than dynamic scenarios, is contrary to the approach supported by
its own members.'' \150\

---------------------------------------------------------------------------
We do not express a view here about the relative merits of a
deterministic and a dynamic approach. However, as noted above, the
Commission has already blanket-licensed over five million fixed earth
stations in the 28.35-28.6 GHz band, which can be ubiquitously deployed
at unspecified locations anywhere within the United States. ESIMs in
this band, like these existing fixed earth stations will be subject to
the same out-of-band emission limits in Sec. 25.202(f) of our
rules.\151\ Despite the large number of operating fixed earth stations,
no commenter has challenged the adequacy of these OOBE limits to
protect mobile services from interference from fixed earth stations.
The number of ESIMs we expect to be deployed in the 28.35-28.6 GHz band
is a smaller than the number of consumer earth stations with fixed
antennas. Moreover, as noted above, a single ESIM will be transmitting
to a satellite receive beam in the same frequency band and
[[Page 53640]]
polarization at any given time and therefore the number of interference
sources that might cause aggregation is also limited by this fact. GSA
has not made any concrete proposals for out-of-band emission limits
specific to ESIMs. Nor did the Commission propose such limits. We
therefore decline to adopt any out-of-band emission limits that would
be specifically applicable to ESIMs at this time. ESIMs must comply
with the out-of-band emission limits specified in Sec. 25.202(f).
---------------------------------------------------------------------------

18.6-18.8 GHz Bands. The National Academy of Sciences, through its
Committee on Radio Frequencies (CORF), expresses concern that ESIMs
operating in the 18.6-18.8 GHz band could cause harmful interference to
earth exploration satellite service (EESS) systems operating around
18.7 GHz.\152\ CORF suggests that ESIMs might cause interference to
EESS satellite receivers by transmitting upward toward EESS satellites
in that range.\153\ CORF also suggests that the introduction of ESIMs
could lead to increased use of the 18.6-18.8 GHz band by FSS networks
for downlink transmissions to ESIM terminals, potentially resulting in
increased reflections of satellite signals off the surface of the Earth
and into EESS satellite receivers.\154\ In its reply comments, Boeing
states that it reached out to CORF representatives to discuss possible
misunderstandings regarding the nature of operations in the 18.6-18.8
GHz band.\155\ Specifically, Boeing notes that given the fact that the
18.3-18.8 GHz band is authorized for downlink transmissions from FSS
satellites, there is no potential for ESIMs to transmit in an upward
direction in this frequency segment.\156\ Second, Boeing pointed out,
that the introduction of ESIMs in the 18.3-18.8 GHz band would not
result in additional satellite downlink transmissions in this spectrum,
it would just increase the number of fixed and mobile earth stations
that would receive those signals on Earth.\157\ Further, as Boeing
states, ``[t]he total number of FSS networks operating in the Ka-band
using geostationary satellites has been governed primarily by the
number of space stations that can successfully operate in a two-degree
spacing environment, not any limits on end user demand for such
capacity.'' \158\ We agree and will continue to be mindful of the need
to protect the interests of the passive scientific users of the radio
spectrum, including users of the Radio Astronomy Service (RAS) and EESS
bands, as observed by CORF.\159\

CORF further suggests that the Commission should clarify the proper
meaning of ``radio line of sight.'' \160\ Specifically, CORF states it
is particularly important to note that in general, the radio and
geometric horizons are different because of atmospheric
refraction.\161\ Thus, for an atmosphere having a standard refractivity
gradient, the effective radius of Earth is about four-thirds that of
the actual radius, which corresponds to approximately 8,500 km.\162\
This increases the radio horizon by about 15 percent compared to the
geometric horizon.\163\ Although we do not incorporate a definition of
``radio line of sight'' in the rules we adopt here, we note that CORF's
interpretation of radio line of sight is widely accepted.

Stratospheric Platforms. The Elefante Group asks the Commission to
ensure that its stratospheric platforms would be considered ESAA to
enable GSO satellite communications with its platforms.\164\ We note
that our ESAA definition does not set an upper limit on the altitude of
the aircraft communicating with a geostationary satellite. In addition,
setting such a limit was not proposed or addressed in this proceeding.
We therefore decline to generally state that stratospheric platforms
are included in the definition of ESAA. Proposals for using FSS
frequencies for communications between such platforms and geostationary
satellites will be examined taking into consideration their specific
characteristics.
---------------------------------------------------------------------------
\164\ Elefante Group Comments at 3. We also decline Elefante
Group's request that the term ``aircraft'' as used within the
definition of ESAA be interpreted broadly to include stratospheric
platforms. Id. at 5.
---------------------------------------------------------------------------
Having addressed the concerns raised in the record regarding the
expansion of ESIMs to the conventional Ka-band frequency bands, we find
it in the public interest to adopt rule changes as proposed in the ESIM
NPRM. Accordingly, we combine footnote NG55 with the relevant portion
of NG52 into NG527A, and state: ``In the bands 11.7-12.2 GHz (space-to-
Earth), 14.0-14.5 GHz (Earth-to-space), 18.3-18.8 GHz (space-to-Earth),
19.7-20.2 GHz (space-to-Earth), 28.35-28.6 GHz (Earth-to-space), and
29.25-30.0 GHz (Earth-to-space), ESIMs may be authorized to communicate
with geostationary satellites in the fixed-satellite service on a
primary basis.'' We also amend Sec. 25.202(a)(8), (a)(10), and (a)(11)
consistent with these changes to reflect all frequency bands.\165\
---------------------------------------------------------------------------
\165\ See Appendix B.
---------------------------------------------------------------------------
ESIMs Application Requirements
In the ESIMs NPRM, the Commission proposed significant
reorganization of the part 25 rules governing all types of ESIMs. As
explained in the ESIMs NPRM, application requirements for FSS earth
station authorizations at fixed and temporary-fixed locations are in
Sec. 25.115. However, the earth station license application
requirements for ESVs, VMESs, and ESAAs are contained in paragraph (b)
of Sec. Sec. 25.221, 25.222, 25.226, and 25.227. The Commission
proposed to move the ESIM application requirements into Sec. 25.115
for better integration of the rules, and we adopt this proposal.
Specifically, the application requirements for a particular frequency
band for all types of ESIM platforms will be contained in paragraphs
(l) (for C-band), (m) (for Ku-band), and (n) (for Ka-band) of Section
25.115. This restructuring is globally supported by the
commenters.\166\

Overview of Earth Station Licensing Rules. As explained in detail
in the ESIMs NPRM, the part 25 licensing rules for FSS earth stations
transmitting digital emissions to GSO FSS space stations provide two
main options for obtaining a license for an earth station at a fixed
location. The first option for obtaining such a license is to
demonstrate compliance (in one of two ways) with default limits on
emissions in directions other than toward the target satellite, which
are referred to as off-axis EIRP density limits.\167\ These limits were
developed to implement the Commission's GSO FSS space station two-
degree orbital spacing policy. They ensure earth station compatibility
with networks using adjacent satellites in a two-degree orbital spacing
environment by controlling the level of emissions from an earth station
that can be transmitted toward adjacent satellite orbital locations.
Under this option, there are, as indicated, two ways to show
compliance. One alternative is to demonstrate that the earth station
antenna gain pattern comports with the off-axis gain limits in Sec.
25.209, and that the antenna input power density comports with limits
in Sec. 25.212. The
[[Page 53641]]
Commission proposed to extend this option to ESIM applications. The
other alternative, already available to ESIM applicants, is to
demonstrate that the off-axis EIRP density of the earth station
emissions comports with the applicable off-axis EIRP density limits in
our ESIM rules.\168\ The second option to obtain a license is to
demonstrate that the operations of the earth stations in the satellite
network have been coordinated with operators of networks using adjacent
satellites that would be affected by emissions of the earth stations
that exceed the default off-axis EIRP density limits, under the
coordination requirements of Sec. 25.220.
---------------------------------------------------------------------------
\167\ The off-axis EIRP density limits are set forth in 47 CFR
25.218 for the C- and Ku-bands and in 47 CFR 25.138 for the Ka-band.
\168\ These provisions are set forth in paragraphs (b)(1) of
Sec. Sec. 25.221, 25.222, 25.226, and 25.227.
---------------------------------------------------------------------------
Commenters support the proposals that both of these licensing
mechanisms be available to ESIM operators.\169\ Regarding the
alternative of certifying compliance with the antenna pattern
specifications in Sec. 25.209 and the antenna input power density
requirements in Sec. 25.212, in addition to the current option of
showing that the Sec. 25.218 off-axis EIRP density limits are met, AC
BidCo states that there is consensus in favor of the Commission's plan
to give ESIM applicants this flexibility.\170\ As explained in more
detail below, we adopt the plan to continue to make both options for
obtaining a license available for ESIMs and revise our rules to allow
ESIM applicants to use both alternatives for showing compliance under
the first option.\171\ As discussed above,\172\ we are eliminating
antenna pointing accuracy requirements for ESIMs. Therefore, the
showings regarding antenna pointing accuracy in paragraphs (b)(1) of
Sec. Sec. 25.221, 25.222, 25.226, and 25.227 will no longer be
required. Similarly, the ESIM application showing required for
applicants proposing to meet the 0.2 degree antenna pointing accuracy
requirement in paragraphs (b)(1)(iii) of Sec. Sec. 25.221, 25.222,
25.226, and 25.227 is no longer relevant. Again, because we are
eliminating the antenna pointing accuracy requirement, the requirement
in the existing ESIM rules that an applicant proposing to operate with
a maximum pointing error greater than 0.2 degrees must declare its
maximum pointing error and show that at the maximum mispointing, the
EIRP density limits are still met, is no longer necessary. Once our new
rules go into effect, applicants will have two options to qualify for a
license: Either comply with the off-axis EIRP density limits, and
provide the information required by Sec. Sec. 25.115(l)-(n)(1), or
coordinate, and provide the information required by Sec. Sec.
25.115(l)-(n)(2). Additionally, we eliminate the pointing accuracy
certification requirements of Sec. Sec. 25.221(b)(1)(iii),
25.222(b)(1)(iii), 25.226(b)(1)(iii), and 25.227(b)(1)(iii),
subparagraphs (A) and (B). We also eliminate the maximum mispointing
declaration requirements that were in paragraphs (b)(1)(iv)(A) and the
cessation of transmissions upon mispointing demonstration requirements
in paragraphs (b)(1)(iv)(B) in Sec. Sec. 25.221, 25.222, 25.226, and
25.227.

\170\ AC BidCo Reply Comments at 4.
\171\ The Joint Commenters support the proposal to permit
applicants to demonstrate technical compliance by either certifying
compliance with (1) the off-axis antenna gain limits in Sec. 25.209
and the antenna input power density limits in Sec. 25.212 or (2)
the off-axis EIRP density limits set forth in Sec. 25.218. Joint
Commenters at 3. See also AC BidCo at 3.
\172\ See para. 0 supra.
---------------------------------------------------------------------------
We adopt, without commenter objection, the proposal to retain the
requirement to provide the off-axis EIRP density showing required by
Sec. Sec. 25.115(g)(1), and the coordination certifications required
by Sec. 25.220(d), for applicants that will not meet the off-axis EIRP
density limits. Paragraphs (b)(2), (b)(2)(i) and (b)(2)(ii) of
Sec. Sec. 25.221, 25.222, 25.226, and 25.227 apply to an applicant
proposing to operate with off-axis EIRP density in excess of the levels
in paragraph (a)(1)(i) or (a)(3)(i) of these sections. Such an
applicant will apply under the provisions in subparagraphs (a)(2) of
Sec. 25.115(l)-(n), which contain substantially the same requirements
for exhibits to its earth station application.
The Commission further proposed to allow ESIM applicants the option
of certifying compliance with the antenna pattern requirements of Sec.
25.209 and the antenna input power density requirements of Sec.
25.212, in lieu of the off-axis EIRP density limits in Sec.
25.218.\173\ This is not a substantive change, because the off-axis
EIRP density limits in Sec. 25.218, and those resulting from the
summing of the antenna input power density limits in Sec. 25.212 and
the antenna off-axis gain limits in Sec. 25.209 are the same as the
off-axis EIRP density limits in the individual ESIM Sec. Sec. 25.221,
25.222, 25.226, and 25.227.\174\ No commenters disagree with this
proposal.\175\ For example, the Joint Commenters note that giving
applicants the option of how to certify off-axis performance provides
regulatory flexibility without sacrificing protection from harmful
interference.\176\

\173\ NPRM, 32 FCC Rcd at 4254, para. 58. For completeness, we
note that cross-references in Sec. 25.212 are revised to reflect

25.227.

Paragraphs (b)(2)(iii) and (b)(2)(iv) of Sec. Sec. 25.221, 25.222,
25.226, and 25.227 require detailed showings that each ESAA transmitter
in the system will automatically cease or reduce emissions within 100
milliseconds after generating EIRP density exceeding the applicable
limits. In the rules proposed in the ESIMs NPRM in Sec. 25.115(l)-
(n)(3)(i), the applicant would have been required to show how the
transmitter will detect exceedance of the off-axis EIRP density mask
and reduce the power of or shut down one or more transmitters within
100 milliseconds of receiving a command to do so from the system's
network control and monitoring center, if the aggregate off-axis EIRP
spectral-densities of the transmitter or transmitters exceed the
relevant off-axis EIRP spectral-density limits.
Many commenters argue against the demonstration requirement in our
proposal. For example, Inmarsat argues that such demonstration at the
application phase that would produce the necessary ``detailed
showings'' would be impractical and burdensome.\177\ Inmarsat submits
that applicants should be able to certify compliance in their
applications, just like the requirements of Sec. 25.227.\178\
Similarly, the Joint Commenters state they cannot support the proposal,
as written, to include a requirement to demonstrate how the cessation
requirement will be met.\179\ Boeing also states that it concurs with
Intelsat and Inmarsat's explanation that it would be appropriate for
the Commission to permit ESIMs applicants to certify that their earth
station terminals will comply with the Commission's shut down
requirements to ensure compliance with the off-axis power spectral
density limits, rather than require a ``demonstration'' of such
compliance.\180\ Such a certification requirement would be consistent
with the Commission's existing rules regarding antenna pointing and
cessation requirements and therefore should be adopted.\181\ Hughes
provides suggested text for
[[Page 53642]]
certification rather than demonstration.\182\

---------------------------------------------------------------------------
After further consideration, we agree with commenters that a
certification is sufficient for the purposes of this application
requirement. We have used a certification process elsewhere in our
rules and it has proven effective at ensuring that licensees satisfy
the technical requirements of our rules.\183\ Thus, Sections 25.115(l)-
(n)(3)(i) will require all applicants to: ``provide a certification
that the ESIM system is capable of detecting and automatically ceasing
emissions when an individual ESIM transmitter exceeds the relevant off-
axis EIRP spectral density limits specified in Sec. 25.218, or the
limits provided to the target satellite operator for operation under
Sec. 25.220.''
---------------------------------------------------------------------------
\183\ See e.g., 47 CFR 25.140(a) (requiring GSO FSS space
station applications to contain certifications of compliance with
certain technical requirements, without submission of any backup
evidence or demonstrations).
---------------------------------------------------------------------------
The certification for a C-band ESV system in Sec. 25.221(b)(3)(v)
regarding compliance with the power limits in Sec. 25.204(h) is
eliminated as no longer necessary. However, we retain a technical and
operational requirement to meet the power limits in Sec. 25.204(h) in
redesignated Sec. 25.228(h)(7).
As proposed, we note that the requirements that were in paragraphs
(b)(5) of Sec. Sec. 25.226 and 25.227 that any VMES or ESAA applicant
filing for a terminal or system and planning to use a contention
protocol must include in its application a certification that its
contention protocol use will be reasonable is substantially the same as
the requirement in Sec. 25.115(i), which we construe as applying to
applications for ESIMs.\184\ Therefore, we will not duplicate the
language from Sec. Sec. 25.226(b)(5) and 25.227(b)(5) in the ESIM
rules brought into Sec. 25.115.
---------------------------------------------------------------------------
\184\ NPRM, 32 FCC Rcd at 4356, para. 65.
---------------------------------------------------------------------------
Further, as proposed, we delete the requirements that were in
paragraphs (b)(8) of Sec. Sec. 25.226 and 25.227 that VMES and ESAA
applicants must submit a radio frequency hazard analysis determining
via calculation, simulation, or field measurement, whether ESAA
terminals, or classes of terminals, will produce power densities that
will exceed the Commission's radio frequency exposure criteria as
duplicative of Sec. 1.1307(b) of the Commission's rules.\185\
Similarly, we delete paragraphs (b)(7) of Sec. Sec. 25.221 and 25.222
and Sec. 25.226(b)(9) as duplicative of 25.115(k)(1), which we
construe as applicable to ESIM applications.\186\
---------------------------------------------------------------------------
\185\ 47 CFR 1.1307(b).
\186\ NPRM, 32 FCC Rcd at 4256, para. 66.
---------------------------------------------------------------------------
Paragraphs (b)(7) of Sec. Sec. 25.226 and 25.227 require that any
VMES or ESAA applicant must include in its application a certification
that it will comply with the requirements of paragraphs (a)(6) of those
sections, and paragraphs (a)(9), (a)(10), and (a)(11) of Sec. 25.227.
The Commission invited comment as to whether the certification
requirement serves a useful purpose, or whether the Commission should
eliminate it, because Commission licensees are required to comply with
all applicable Commission rules. AC BidCo comments that ``eliminating
this certification requirement will have no effect on the substantive
technical and operational standards that an ESIM operator must meet.''
\187\ Because licensees will be required to comply with these
provisions even without the certification requirement, we agree, and
will no longer require such a certification.
---------------------------------------------------------------------------
\187\ AC BidCo Comments at 4.
---------------------------------------------------------------------------
We proposed to remove Sec. 25.226(b)(8), which states, in part,
that all VMES applicants must demonstrate that their VMES terminals are
capable of automatically ceasing transmissions upon the loss of
synchronization or within 5 seconds upon loss of reception of the
satellite downlink signal, whichever is the shorter timeframe. This is
redundant with Sec. 25.271(g), which applies by its terms to all
transmitting earth stations. It is not necessary to duplicate the
provisions in Sec. 25.271(g) in a rule intended specifically for
ESIMs. Additionally, the requirement for radiation hazard mitigation
that had been included in Sec. 25.226(b)(8) is incorporated into Sec.
25.228(d), as explained above.
Finally, as proposed, we retain the requirements in paragraphs
(b)(4) of Sec. Sec. 25.221, 25.222, 25.222, 25.226, and 25.227, in
paragraphs (b)(5) of Sec. Sec. 25.221 and 25.222 and (b)(6) of
Sec. Sec. 25.226 and 25.227, and in paragraphs (b)(6) of Sec. Sec.
25.221 and 25.222 and (b)(8) of Sec. Sec. 25.226 and 25.227, and move
those requirements into paragraphs (l)-(n) of Sec. 25.115.\188\
Inmarsat supports this proposal as promoting uniformity and
efficiency.\189\

Merging Sec. Sec. 25.130 and 25.131 Into Sec. 25.115
We adopt the Commission's proposals to move the requirements in
Sec. 25.130 into Sec. 25.115(a)(5)-(10).\190\ We note that there is a
difference between what the Commission proposed in the ESIMs NPRM and
the version that we adopt in this Report and Order because Sec. 25.130
was updated by the Spectrum Frontiers Second Report and Order.\191\ The
changes to Sec. 25.130(b) are brought into Sec. 25.115(a)(6)(i)-(iv),
and the Note to paragraph (g) is now incorporated as a Note to (a)(10).
Further, the Note is revised to eliminate cross-references to the
individual ESIM Sec. Sec. 25.221, 25.222, 25.226, and 25.227, and is
revised to cross-reference the appropriate paragraphs of Sec. 25.115.
---------------------------------------------------------------------------
\190\ A list of the existing paragraphs in Sec. 25.130 and the
corresponding proposed paragraphs in Sec. 25.115 appears in Table 1

---------------------------------------------------------------------------
Further, the last sentence of Sec. 25.130(a) previously stated
that ``applicants that are not required to submit applications on Form
312EZ'' must submit the information in subparagraphs (1)-(5) of Sec.
25.130(a) as an attachment to their applications. The use of Form 312EZ
is not mandatory, but rather, use is an option available to applicants
under some circumstances. Therefore, as proposed, we change the word
``required'' to ``permitted''. We reserve Sec. 25.130. Cross-
references to this section are redirected to the appropriate paragraphs
in Sec. 25.115.
Similarly, we move all requirements regarding receive-only earth
stations, with minor revisions, from Sec. 25.131 into Sec.
25.115(b).\192\ We reserve Sec. 25.131, and redirect any cross-

Other Miscellaneous Changes to Sec. 25.115
We adopt the proposals to reorganize and remove sections that are
redundant or better included elsewhere in the reorganized
sections.\193\ Specifically, we incorporate the language regarding
instructions for electronically filing from Sec. 25.115(a)(4), into
Sec. 25.115(a)(1). We revise the cross-references in Sec.
25.115(k)(1) to Sec. Sec. 25.221, 25.226, and 25.227 to refer instead
to the proposed paragraphs (l)-(n) of Sec. 25.115, consistent with the
unifying of the application requirements into Sec. 25.115. Similarly,
we adopt non-substantive changes to Sec. 25.115(k)(2). The proposed
changes to 25.115(c)(1) discussed in the ESIMs NPRM were previously
adopted in the NGSO FSS Report and Order.\194\

Changes Required in Additional Sections of the Commission's Rules:
Sec. Sec. 25.129, 25.133, 25.140, 25.202, 25.204, 25.209, and 25.258
and Notes to the Table of Frequency Allocations
The Commission proposed several additional changes in other
sections of part 25 to harmonize the various rule sections involving
ESIMs. We are updating cross-references to sections which are being
eliminated or reorganized accordingly. Specifically, we eliminate
references to Sec. Sec. 25.221, 25.222, 25.226 and 25.227 in
Sec. Sec. 25.202(a)(8) and 25.140(d)(1). Section 25.140(d)(1) also has
an updated reference to Sec. 25.218. Additionally, we update the
cross-reference to Sec. 25.138(a) in Sec. 25.140(a)(3)(iii) to point
to Sec. 25.218(i), which will contain the off-axis EIRP density limits
contained in Sec. 25.138(a). Similarly, we revise the cross-reference
to Sec. 25.138(a) in Sec. 25.258(b) regarding operation of
ubiquitously deployed GSO FSS earth stations in the 29.25-29.5 GHz
frequency band to point to Sec. 25.218(i). We are also eliminating
cross-references to Sec. Sec. 25.221, 25.222, 25.226, and 25.227 in
Sec. Sec. 25.115(g)(1)(iv) and (vii). Further, we are eliminating
cross-references to Sec. 25.138, e.g. from Sec. Sec.
25.115(c)(3)(i)(B), (c)(3)(ii), and 25.132(d). In Sec. 25.133(d), the
reference to Sec. 25.131 is updated to reflect the requirement being
reorganized into Sec. 25.115(b).
Because Sec. 25.138 is being removed and reserved, we remove the
reference to it in Sec. 25.129(c).\195\ For the same reasons, we
remove references to Sec. 25.221 in Sec. 25.140(a)(3)(i), and to
Sec. Sec. 25.222, 25.226, and 25.227 in Sec. 25.140(a)(3)(ii).\196\
For completeness, we also note that we eliminate similar obsolete
cross-references in Sec. 25.220(a).
---------------------------------------------------------------------------
\195\ See Appendix B.
\196\ Id.
---------------------------------------------------------------------------
We revise the cross-references to Sec. Sec. 25.130 and 25.131 in
Sec. 25.209(c)(1) to reflect the move of the particular requirements
to Sec. Sec. 25.115(b)(2) and (b)(4). Similarly, we revise Sec.
25.209(f) to eliminate the reference to Sec. Sec. 25.138, 25.221,
25.222, 25.226, and 25.227, and to refer instead to Sec. 25.218, as
well as other clarifying changes. These changes are necessary to
reflect the changes to requirements for demonstrations for a non-
conforming antenna. We also consolidate the requirements in paragraphs
(i)-(k) of Sec. 25.204 into Sec. 25.228(j)(2).\197\
---------------------------------------------------------------------------
\197\ A list of the existing paragraphs in Sec. 25.204 and the
corresponding proposed paragraphs in Sec. 25.228 appears in Table 6
of Appendix C.
---------------------------------------------------------------------------
In addition to moving the ESIM-related sentence of footnote NG52 of
the Table of Frequency Allocations into NG527A \198\ that language in
footnote NG52 is also revised to refer to ESIMs rather than ESVs,
VMESs, and ESAAs to be consistent with the terminology adopted in this
Report and Order.\199\ Finally, footnote US133 of the Table of
Frequency Allocation contained cross-references to sub-paragraphs of
Sec. Sec. 25.226 and 25.227 that are updated to point to the
appropriate sub-paragraphs of Sec. 25.228.\200\
---------------------------------------------------------------------------
\198\ 47 CFR 2.106.
\199\ See Appendix B--Final Rules.
\200\ We also adopt the proposal to add footnotes 5.484B and
5.527A, which relate to ESIM use and were adopted in WRC-15, to the
International Table.

Procedural Matters
In this document, we have assessed the effects of reducing the
application burdens of GSO FSS ESIM applicants, and find that doing so
will serve the public interest and is unlikely to directly affect
businesses with fewer than 25 employees.

Sec. 25.228 Operating and coordination requirements for earth
stations in motion (ESIMs).
(a) ESIM transmissions must comport with the applicable EIRP
density limits in Sec. 25.218, unless coordinated pursuant to the
requirements in Sec. 25.220.
(b) Each ESIM must be self-monitoring and, should a condition occur
that would cause the ESIM to exceed its authorized off-axis EIRP
density limits, the ESIM must automatically cease transmissions within
100 milliseconds, and not resume transmissions until the condition that
caused the ESIM to exceed those limits is corrected.
(c) Each ESIM must be monitored and controlled by a network control
and monitoring center (NCMC) or equivalent facility. Each ESIM must
comply with a ``disable transmission'' command from the NCMC within 100
milliseconds of receiving the command. In addition, the NCMC must
monitor the operation of each ESIM in its network, and transmit a
``disable transmission'' command to any ESIM that operates in such a
way as to exceed the authorized off-axis EIRP density limit for that
ESIM or for all ESIMs that simultaneously transmit on the same
frequency to the same target satellite receiving beam. The NCMC must
not allow the ESIM(s) under its control to resume transmissions until
the condition that caused the ESIM(s) to exceed the authorized EIRP
density limits is corrected.
(d) ESIM licensees must ensure installation of ESIM terminals on
vehicles by qualified installers who have an understanding of the
antenna's radiation environment and the measures best suited to
maximize protection of the general public and persons operating the
vehicle and equipment. An ESIM terminal exhibiting radiation exposure
levels exceeding 1.0 mW/cm\2\ in accessible areas, such as at the
exterior surface of the radome, must have a label attached to the
surface of the terminal warning about the radiation hazard and must
include thereon a diagram showing the regions around the terminal where
the radiation levels could exceed the maximum radiation exposure limit
specified in 47 CFR 1.1310 Table 1.
(e) The following requirements govern all ESV operations:
(1) ESV operators must control all ESVs by a NCMC located in the
United States, except that an ESV on U.S.-registered vessels may
operate under control of a NCMC location outside the United States
provided the ESV operator maintains a point of contact within the
United States that will have the capability and authority to cause an
ESV on a U.S.-registered vessel to cease transmitting if necessary.
(2) There must be a point of contact in the United States, with
phone number and address, available 24 hours a day, seven days a week,
with authority and ability to cease all emissions from the ESVs, either
directly or through the facilities of a U.S. NCMC or a NCMC located in
another country with which the United States has a bilateral agreement
that enables such cessation of emissions.
(3) ESV NCMC operators communicating with ESVs on vessels of
foreign registry must maintain detailed information on each such
vessel's country of registry and a point of contact for the relevant
administration responsible for licensing those ESVs.
(f) For all VMES operations, there must be a point of contact in
the United States, with phone number and address, available 24 hours a
day, seven days a week, with authority and ability to cease all
emissions from the VMESs.
(g) The following requirements govern all ESAA operations:
(1) There must be a point of contact in the United States, with
phone number and address, available 24 hours a day, seven days a week,
with authority and ability to cease all emissions from the ESAAs.
(2) All ESAA terminals operated in U.S. airspace, whether on U.S.-
registered civil aircraft or non-U.S.-registered civil aircraft, must
be licensed by the Commission. All ESAA terminals on U.S.-registered
civil aircraft operating outside of U.S. airspace must be licensed by
the Commission, except as provided by section 303(t) of the
Communications Act.
(3) Prior to operations within a foreign nation's airspace, the
ESAA operator must ascertain whether the relevant administration has
operations that could be affected by ESAA terminals, and must determine
whether that administration has adopted specific requirements
concerning ESAA operations. When the aircraft enters foreign airspace,
the ESAA terminal must operate under the Commission's rules, or those
of the foreign administration, whichever is more constraining. To the
extent that all relevant administrations have identified geographic
areas from which ESAA operations would not affect their radio
operations, ESAA operators may operate within those identified areas
without further action. To the extent that the foreign administration
has not adopted requirements regarding ESAA operations, ESAA operators
must coordinate their operations with any potentially affected
operations.
(h) The following requirements govern all operations in the 3700-
4200 MHz (space-to-Earth) and 5925-6425 MHz (Earth-to-space) frequency
bands of ESVs receiving from or transmitting to GSO satellites in the
Fixed-Satellite Service:
(1) ESVs must not operate in the 5925-6425 MHz (Earth-to-space) and
3700-4200 MHz (space-to-Earth) frequency bands on vessels smaller than
300 gross tons.
(2) ESV operators transmitting in the 5925-6425 MHz (Earth-to-
space) frequency band to GSO satellites in the Fixed-Satellite Service
(FSS) must not seek to coordinate, in any geographic location, more
than 36 megahertz of uplink bandwidth on each of no more than two GSO
FSS satellites.
(3) ESVs, operating while docked, for which coordination with
terrestrial stations in the 3700-4200 MHz band is completed in
accordance with Sec. 25.251, will receive protection from such
terrestrial stations in accordance with the coordination agreements,
for 180 days, renewable for 180 days.
(4) ESVs in motion must not claim protection from harmful
interference from any authorized terrestrial stations to which
frequencies are already assigned, or any authorized terrestrial station
to which frequencies may be assigned in the future in the 3700-4200 MHz
(space-to-Earth) frequency band.
(5) ESVs operating within 200 km from the baseline of the United
States, or within 200 km from a U.S.-licensed fixed service offshore
installation, must complete coordination with potentially affected
U.S.-licensed fixed service operators prior to operation. The
coordination method and the interference criteria objective will be
determined by the frequency coordinator. The details of the
coordination must be maintained and available at the frequency
coordinator, and must be filed with the Commission electronically via
the International Bureau Filing System (https://licensing.fcc.gov/myibfs/) to be placed on public notice. The coordination notifications
must be filed in the form of a statement referencing the relevant call
signs and file numbers. Operation of each individual ESV may commence
immediately after the public notice that identifies the notification
sent to the Commission is released. Continuance of operation of that
ESV for the duration of the coordination term must be dependent upon
successful completion of the normal public notice process. If, prior to
the end of the 30-day comment period of the public notice, any
objections are received from U.S.-licensed Fixed Service operators that
[[Page 53658]]
have been excluded from coordination, the ESV licensee must immediately
cease operation of that particular station on frequencies used by the
affected U.S.-licensed Fixed Service station until the coordination
dispute is resolved and the ESV licensee informs the Commission of the
resolution. As used in this section, ``baseline'' means the line from
which maritime zones are measured. The baseline is a combination of the
low-water line and closing lines across the mouths of inland water
bodies and is defined by a series of baseline points that include
islands and ``low-water elevations,'' as determined by the U.S.
Department of State's Baseline Committee.
(6) An ESV must automatically cease transmission if the ESV
operates in violation of the terms of its coordination agreement,
including, but not limited to, conditions related to speed of the
vessel or if the ESV travels outside the coordinated area, if within
200 km from the baseline of the United States, or within 200 km from a
U.S.-licensed fixed service offshore installation. Transmissions may be
controlled by the ESV network control and monitoring center. The
frequency coordinator may decide whether ESV operators should
automatically cease transmissions if the vessel falls below a
prescribed speed within a prescribed geographic area.
(7) ESV transmissions in the 5925-6425 MHz (Earth-to-space) band
shall not exceed an EIRP spectral density towards the radio-horizon of
17 dBW/MHz, and shall not exceed an EIRP towards the radio-horizon of
20.8 dBW. The ESV network shall shut-off the ESV transmitter if either
the EIRP spectral density towards the radio-horizon or the EIRP towards
the radio-horizon is exceeded.
(i) For ESAA transmissions in the 14.0-14.5 GHz band from
international airspace within line-of-sight of the territory of a
foreign administration where fixed service networks have primary
allocation in this band, the maximum power flux density (pfd) produced
at the surface of the Earth by emissions from a single aircraft
carrying an ESAA terminal must not exceed the following values unless
the foreign Administration has imposed other conditions for protecting
its fixed service stations:
----------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------------
-132 + 0.5 [middot] [thgr]........ dB(W/(m\2\ [middot] For....................... [thgr] <= 40[deg].
MHz)).
-112.............................. dB(W/(m\2\ [middot] For....................... 40[deg] <[thgr]
MHz)). <=90[deg].
----------------------------------------------------------------------------------------------------------------
Where: [thgr] is the angle of arrival of the radio-frequency wave
(degrees above the horizontal) and the aforementioned limits relate to
the pfd under free-space propagation conditions.
(j) The following requirements govern all ESIMs transmitting to GSO
satellites in the Fixed-Satellite Service in the 14.0-14.5 GHz band:
(1) Operations of ESIMs in the 14.0-14.2 GHz (Earth-to-space)
frequency band within 125 km (for ESVs and VMESs) or within radio line
of sight (for ESAAs) of the NASA TDRSS facilities on Guam (latitude
13[deg]36'55'' N, longitude 144[deg]51'22'' E), White Sands, New Mexico
(latitude 32[deg]20'59'' N, longitude 106[deg]36'31'' W and latitude
32[deg]32'40'' N, longitude 106[deg]36'48'' W), or Blossom Point,
Maryland (latitude 38[deg]25'44'' N, longitude 77[deg]05'02'' W) are
subject to coordination with the National Aeronautics and Space
Administration (NASA) through the National Telecommunications and
Information Administration (NTIA) Interdepartment Radio Advisory
Committee (IRAC). Licensees must notify the International Bureau once
they have completed coordination. Upon receipt of such notification
from a licensee, the International Bureau will issue a public notice
stating that the licensee may commence operations within the
coordination zone in 30 days if no party has opposed the operations.
When NTIA seeks to provide similar protection to future TDRSS sites
that have been coordinated through the IRAC Frequency Assignment
Subcommittee process, NTIA will notify the Commission's International
Bureau that the site is nearing operational status. Upon public notice
from the International Bureau, all Ku-band ESIM licensees must cease
operations in the 14.0-14.2 GHz band within 125 km (for ESVs and VMESs)
or within radio line of sight (for ESAAs) of the new TDRSS site until
the licensees complete coordination with NTIA/IRAC for the new TDRSS
facility. Licensees must notify the International Bureau once they have
completed coordination for the new TDRSS site. Upon receipt of such
notification from a licensee, the International Bureau will issue a
public notice stating that the licensee may commence operations within
the coordination zone in 30 days if no party has opposed the
operations. The ESIM licensee then will be permitted to commence
operations in the 14.0-14.2 GHz band within 125 km (for ESVs and VMESs)
or within radio line of sight (for ESAAs) of the new TDRSS site,
subject to any operational constraints developed in the coordination
process.
(2) Within 125 km (for ESVs and VMESs) or within radio line of
sight (for ESAAs) of the NASA TDRSS facilities identified in paragraph
(j)(1) of this section, ESIM transmissions in the 14.0-14.2 GHz (Earth-
to-space) band shall not exceed an EIRP spectral density towards the
horizon of 12.5 dBW/MHz, and shall not exceed an EIRP towards the
horizon of 16.3 dBW.
(3) Operations of ESIMs in the 14.47-14.5 GHz (Earth-to-space)
frequency band in the vicinity (for ESVs and VMESs) or within radio
line of sight (for ESAAs) of radio astronomy service (RAS)
observatories observing in the 14.47-14.5 GHz band are subject to
coordination with the National Science Foundation (NSF). The
appropriate NSF contact point to initiate coordination is
Electromagnetic Spectrum Management Unit, NSF, Division of Astronomical
Sciences, 2415 Eisenhower Avenue, Arlington VA 22314; Email:
[email protected]. Licensees must notify the International Bureau once they
have completed coordination. Upon receipt of the coordination agreement
from a licensee, the International Bureau will issue a public notice
stating that the licensee may commence operations within the
coordination zone in 30 days if no party has opposed the operations.

(4) When NTIA seeks to provide similar protection to future RAS
sites that have been coordinated through the IRAC Frequency Assignment
Subcommittee process, NTIA will notify the Commission's International
Bureau that the site is nearing operational status. Upon public notice
from the International Bureau, all Ku-band ESIMs licensees must cease
operations in the 14.47-14.5 GHz band within the relevant geographic
zone (160 kms for single-dish radio observatories and Very Large Array
antenna systems and 50 kms for Very Long Baseline Array antenna systems
for ESVs and VMESs, radio line of sight for ESAAs) of the new RAS site
until the licensees complete coordination for the new RAS facility.
Licensees must notify the International Bureau once they have completed
coordination for the new RAS site and must submit the coordination
agreement to the Commission. Upon receipt of such notification from a
licensee, the International Bureau will issue a public notice stating
that the licensee may commence operations within the coordination zone
in 30 days if no party opposed the operations. The ESIMs licensee then
will be permitted to commence operations in the 14.47-14.5 GHz band
within the relevant coordination distance around the new RAS site,
subject to any operational constraints developed in the coordination
process.
(5) ESIMs licensees must use Global Positioning Satellite-related
or other similar position location technology to ensure compliance with
the provisions of subparagraphs 1-3 of this paragraph.
