National Positioning, Navigation, and Timing Resilience and Security Act of 2015

National Positioning, Navigation, and Timing Resilience and Security Act of 2015

Directs the Department of Defense to provide for the establishment of a reliable land-based positioning, navigation, and timing system to complement and back up the global positioning system (GPS) to ensure the availability of uncorrupted or non-degraded signals for military and civilian users if GPS signals are corrupted, degraded, unreliable, or otherwise unavailable.

Requires the system to: (1) be wireless, terrestrial, and wide-area; (2) provide a precise, high-power 100 kilohertz signal; (3) be able to penetrate underground and inside buildings; (4) take advantage of existing, unused government long-range navigation system (LORAN) infrastructure and work in concert with enhanced long-range navigation systems (eLORAN); and (5) incorporate private sector expertise.
