GPS Resiliency Report Act

S 2277, the GPS Resiliency Report Act, requires the Secretary of Defense to submit a report to Congress within one year of the bill's enactment. The report must assess risks to U.S. and allied access to GPS during conflicts or attacks, evaluate competitor nations' capabilities to disrupt GPS (including China, Russia, Iran, and North Korea), and review current efforts to develop backup navigation systems (like space-based and quantum sensing technologies). It also mandates a framework for a terrestrial-based GPS redundancy system operational within 15 years. The bill directly affects the Department of Defense (as the preparer) and Congress (as the recipient), focusing solely on requiring this analysis without changing existing policies.
