I'd assume/hope Navy crew would be trained in and regularly drill non GPS navigation techniques. Even in the civilian/recreational sailing world you do (or at least did when I took my exam 15 years ago) blind pilotage where you have to sit below deck and navigate the boat through a harbour, without use of GPS, as a standard part of yachtmaster exams. Celestial navigation and use of a sextant was required for ocean yachtmaster.
- toss1 3y agoThis is so critical, especially in warfare — retaining the ability to function when fragile systems are degraded. And we see examples every day where GPS is rendered locally/regionally unusable and/or spoofed, nevermind the likely warfare scenario where GPS satellites are directly attacked. I have no clue why you are getting downvoted. Evidently some are just so enamored of stuff they have on their phones they cannot imagine it going away. In any attack or general failure, they'll be the most lost!

Civilian-grade jammers may not be sufficient to interfere with encrypted military GPS, but the Iranians were able to hijack US Predator drones via GPS spoofing: https://www.securityweek.com/reports-say-us-drone-was-hijacked-iran-through-gps-spoofing/ https://www.securityweek.com/reports-say-us-drone-was-hijack...
