GPS systems can be jammed and spoofed. Quantum gravity sensors can't be fooled. A prototype tested in Australia provided a ship with accurate navigation with no GPS sensing for 144 hours.

“You can’t spoof gravity without literally moving a mountain,” says Michael J. Biercuk in the article. Is the future of navigation with un-jammable quantum sensing?
>A novel quantum sensor that measures gravity changes by detecting variations in the travel time of falling atoms has been tested in a first of its kind experiment aboard an Australian navy ship.
>The sensor — a dual gravimeter — has been developed by Australian company Q-CTRL and could reach the market in late 2026. During the tests onboard the Australian Royal Navy’s aviation training vessel MV Sycamore, the crew was able to navigate for 144 hours without GPS access using the autonomous prototype system.
>According to Michael J. Biercuk, Q-CTRL CEO and founder, the test marked the first time such a sensor was used in a practical scenario aboard a moving vehicle.
I’m not even going to try to pretend to understand how this thing works – but if it’s really as they say, this seems like kind of a big deal.
More precise than Inertial systems and independent of GPS? The world is your oyster.
