ACTION: Notice; request for public comments. AGENCY: The purpose of this notice is to seek comment from the public and industry regarding plans by the United States Air Force to broadcast preoperational L2C and L5 civil navigation (CNAV) messages from certain Global Positioning System (GPS) satellites beginning in April 2014. These messages will be formatted in accordance with Interface Specifications IS–GPS–200G and IS–GPS–705C, each dated 31 Jan 2013. However, a preoperational signal means the availability and other characteristics of the broadcast signal may not comply with all requirements of the relevant Interface Specifications and should be employed at the users’ own risk. The Department of Transportation seeks comments on: (a) The benefits, risks, or issues to users from this plan, including comments on the appropriate timeline for broadcasting preoperational CNAV messages. Comments are requested from industry on: (b) the receiver development benefits and other intended uses of pre-operational signals, and (c) the benefits and potential impacts to users of continuous preoperational CNAV messages with L2C and L5 signals set healthy. DATES: Submit comments on or before April 4, 2014.

SUPPLEMENTARY INFORMATION: Background and Purpose The United States Government is currently adding new civil signals to the GPS constellation, including L2C and L5. The Commander of the United States Air Force Space Command directed that, beginning in April 2014, GPS satellites will broadcast navigation messages on the L2C and L5 signals to facilitate development of compatible user equipment and CNAV operational procedures. This extended preoperational continuous broadcast is the next phase of development of a new capability based on the testing done in June 2013, per 78 Federal Register Notice 17185, March 20, 2013. This broadcast message capability is to be implemented using current GPS ground control capabilities in advance of more automated capabilities to become operational with the Next Generation GPS Operational Control System, called OCX.

Currently, seven GPS IIR–M satellites broadcast L2C and four GPS IIF satellites broadcast L2C and L5. On average, users may expect at least one L2C-broadcasting satellite to be in view at all times. The CNAV message content will include Broadcast Message Types (MT) 10, 11, 30, and 33 (as defined in IS–GPS–200G and IS– GPS–705C, see https://www.gps.gov/ technical/icwg/) in lieu of the currently transmitted MT–0. The Air Force intends to broadcast L2C and L5 messages with the health bits set healthy, as was the case during the June 2013 test. The CNAV data uploads will be integrated into current operations, but initially the uploads to each appropriate satellite will occur only twice per week. In December 2014, CNAV uploads are planned to be at the normal rate of once per day for each appropriate satellite. Consequently, users should expect L2C and L5 signals with CNAV messages to provide increased user range error compared to legacy civil signals between April and December 2014. After December 2014, the accuracy of the L2C and L5 signals with CNAV messages is expected to meet or exceed that of legacy signals. Future tests and implementation of the remaining CNAV message types will be announced under separate Federal Register Notices. The pre-operational CNAV messages are being made available for user familiarization and for equipment development. They should not be considered operational pending availability of OCX monitoring and control capabilities, and therefore they should not be used for safety-of-life or other critical purposes. Caveats indicating ‘‘Developmental Signal-inSpace, non-operational’’ will be included in Notice Advisory to NAVSTAR Users (NANUs). The Department of Transportation seeks comments on benefits, risks, or issues to users from this plan, including comments on the appropriate timeline for implementing the plan. Comments are requested from industry on the receiver development benefits and other intended uses of pre-operational signals. Comments are also requested on the benefits and potential impacts to users of continuous pre-operational CNAV broadcast with signals set healthy.
