Answer:
Global Positioning System locates through a process called triangulation.
Triangulation is a way to determine the difference between the time that your running watch receives a GPS signal and the time that GPS signal was sent to your running watch. The difference between sending and receiving a GPS signal determines how far away the satellite is.
That process gets repeated with satellites that sit further away from the watch receiver, which pins down its exact location and continues to track the receiver throughout the activity.
