Resilient LEO PNT Act

HR 4344, the Resilient LEO PNT Act, directs the Air Force to fund a demonstration project with U.S.-based commercial satellite companies to develop a backup system for GPS. The bill requires this system to operate without GPS, work with existing civilian GPS equipment, resist jamming/spoofing better than current GPS, and deliver high-precision timing (under 10 nanoseconds) and positioning (under 30 centimeters). It specifically targets commercial providers meeting U.S. office and service criteria, aiming to create a resilient low-Earth orbit satellite capability. The demonstration must be completed within 18 months, with potential follow-on contracts for successful providers to move toward operational use.
