GPS-free navigation at sea was demonstrated using quantum sensors that measure gravitational field changes to determine their location.

    Cue magnetic mines, but where are you getting the gravitic mines from?

      If it works off tiny changes in gravity, a really big rock would work.

        Our mission is to sneak this Ayers rock under the boat without being detected. In and out. 45 minutes tops.

          I was going to say something about the scale of gravity changes needed, but your take is way better. Cheers.

        Well, to be fair, a big rock would also work on a GPS device, if applied directly to it.

      They just trigger degauss on 10,000 CRT monitors simultaneously.
