Resilient PNT with fault-tolerant authoritative time sourcing across processors counters unauthorised system-clock biasing for evasion.
Resilient PNT with GNSS authentication and trusted-source verification defeats GPS-ephemeris biasing of the on-board position estimate.
Resilient PNT including GNSS authentication mechanisms and fault-tolerant time sourcing is the named defense against geofence-conditional malware that triggers on PNT inputs.
Resilient PNT including fault-tolerant authoritative time sourcing is the named defense against unauthorised system-clock modifications.
Resilient PNT with GNSS authentication and fault-tolerant time sourcing across SpaceWire to ~1 µs is the named defense against time spoofing.
