This bill mandates the Secretary of the Air Force to carry out a capability demonstration project, known as the Commercial Low Earth Orbit Resilient Positioning, Navigation, and Timing Capability Demonstration . The primary goal is to obtain resilient PNT capabilities by leveraging commercial LEO satellite systems. The Secretary is directed to identify and contract with at least one U.S.-based commercial service provider to conduct this demonstration within 18 months of the contract award. The demonstrated system must possess several key technical capabilities, including the ability to operate without Global Positioning System (GPS) services and be compatible with existing civilian GPS L1 or L5 user equipment without hardware modifications. It must also exhibit greater resistance to jamming and spoofing threats than current GPS services, provide timing accuracy under 10 nanoseconds, and position accuracy under 30 centimeters. Furthermore, the system needs to demonstrate rapid service restoration if satellites are disabled. The Secretary will evaluate providers based on factors such as a demonstrated commercial business case, technological readiness of space and ground networks, user equipment readiness, manufacturing feasibility, and Federal Communications Commission authorization. Following a successful demonstration, the Secretary may award a follow-on production contract for operational deployment. Within two years of enactment, the Secretary must brief Congress on the project's results, provider assessments, and a strategy for operational scaling.
