World's first GPS-free quantum navigation trial succeeds at sea

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

    Why do we expect this quantum map of gravity and magnetic fields to be permanent?

      It is not permanent, but the changes are slow enough

      Why do you think they expect it to be permanent? We survey all kinds of stuff like this all the time.

        Geography and celestial maps are permanent (mostly).

        The next question is, how long until a quantum measured map becomes unrecognised? Is the half life years or hours?

          I’m guessing remote sensing will be involved with keeping the maps accurate.
