Strengthening Resilience of Positioning, Navigation, and Timing Services
summary
U.S. critical infrastructure is highly dependent on GPS and GNSS and a complete loss can cost $1 billion a day; weak open signals are trivially jammed with a $30 jammer or spoofed with a $200 software defined radio plus GitHub software. The 2019 GPS week rollover grounds airliners for 7–10 days in some cases. NIST publishes NISTIR 8323, a CSF-based PNT profile produced with ~75–80 collaborators, and recommends: inventory PNT-dependent assets (3 months), identify sources and alternatives (time-over-fiber, dual sources), and implement procedures and risk management (6 months).
