GPS works by using signals from satellites orbiting Earth. Your phone listens to at least four of them and calculates how long their signals take to reach you. By measuring that time, it figures out your exact location. It’s kind of like cosmic triangulation that works even while you’re moving.

Your phone tells a few satellites that it exists and they can triangulate.
GPS is similar to a radio receiver. You can listen to the radio even when in a moving car.
