DOT Report: L-band, UHF, LF and Fibre PNT Needed to Protect US
In a report issued on Jan. 14, the Department of Transportation (DOT) outlined the results of its GPS Backup Technology Demonstration project. As officials had previously projected, it called for a system-of-systems approach using multiple complementary technologies. The report called for an architecture that included signals from space in the L-band, terrestrial broadcasts in the ultra high frequency (UHF) and low frequency (LF) spectra, and a fibre backbone to synchronise and feed precise time to terrestrial transmitters.
The demonstration project and report were mandated by Congress in legislation passed in late 2017 and funded in early 2018. Delays within the administration resulted in the project beginning in early 2019. Of 21 firms that offered to demonstrate their wares, 11 were selected.
