Uh.. this isn’t how GPS works.

The signals from the satellites are the same regardless of the receiver. The only thing that was different was selective availability where civilians got a less accurate signal but even this has been removed.

Yes, but to my knowledge you could potentially spoof a receiver (not the satellites) to think it's somewhere else.

That's why they use crypto.

Kinda like jamming with a stronger signal, but with a valid one saying you're not where you are.
