Cheap GPS receivers already have to do a bunch of tricks to get to the "okay" state they're currently at.
Military devices either use GPS, star tracking, dead reckoning, or some combination. For submarines, detecting gravity variations could also be used, but it wouldn't rely on the quantization of gravity.
In many places on land, you can use terrain landmarks.
Since most things are already either covered, or have improvements in development, I don't really see investment for your idea.
The improvements might even use "quantum" or "gravity", but I don't think the use of "quantum gravity" is very likely.
- JumpCrisscross 2y agoYou’re mixing up general relativity with quantum gravity.
- Vecr 2y agoI'm not exactly sure what you're saying. I know you can have gravitons without "quantum gravity" (as incomplete theories). I'm responding to a commenter on applications. In a global position finding system, gravitational effects could be used, as could be quantum effects. Maybe even both in the same system. It seems really doubtful to me a practical system would depend on anything graviton related.
- JumpCrisscross 2y agoYou buried your lede. The “tricks” you describe relate to GR. I missed that you’re essentially saying “no.”
