What is the recommended action regarding restarting GPS systems after spoofing is suspected?

When GPS spoofing is suspected, the goal is to protect the integrity of navigation data and avoid reintroducing potentially false information. Restarting the GPS receiver can cause it to re-acquire signals and may again lock onto the spoofed transmitter, leaving the vessel with misleading position and time data. Since the spoofing source may still be broadcasting, a reboot doesn’t clear the threat; it can simply reestablish the same false solution and confuse the bridge, autopilot, or navigator. The safer course is to refrain from restarting the GPS, isolate or disable the GPS input as directed by your spoofing response procedures, and rely on independent navigation sources (dead reckoning, inertial navigation, radar, ECDIS cross-checks, celestial navigation if possible) while alerting appropriate authorities and following ship’s contingency steps. This approach maintains navigation safety until the spoofing threat is resolved or cleared.
