Office of the Secretary of Transportation May 3, 2019 – Federal Register Recent Federal Regulation Documents

The U.S. Department of Transportation (DOT) is planning to conduct a field demonstration of technologies with a Technology Readiness Level (TRL) of six or higher, as described in the Federal Highway Administration Technology Readiness Level Guidebook,\1\ that are capable of providing backup positioning, navigation, and/or timing services to critical infrastructure (CI) in the event of a temporary disruption to GPS. This demonstration effort also is expected to encompass technologies capable of providing complementary PNT functions to GPS by either expanding PNT capabilities, including cross checks, or extending them to GPS or Global Navigation Satellite System (GNSS)- denied or degraded user environments. DOT is issuing this Request for Information (RFI) to seek levels of interest and additional information from PNT technology vendors on participation in the demonstration. The information requested can be found in the supplemental information section of this RFI.
