Can GPS work without satellites?
A quantum accelerometer has been developed that could pave the way for global navigation technologies, without having to rely on satellites and GPS technology. … The quantum accelerometer is a self-contained system that does not rely on any external signals.
How does GPS work today?
GPS is a system of 30+ navigation satellites circling Earth. We know where they are because they constantly send out signals. A GPS receiver in your phone listens for these signals. Once the receiver calculates its distance from four or more GPS satellites, it can figure out where you are.
