If you have ever in your life used a map and compass, you will not have problem understanding a little about how the GPS works. All you need to have is three points of reference to find the spot where you are on the map. The intersecting line from the reference points locates you where you are on the map.
It’s the satellites orbiting the earth that emit unique signals which can be received by a GPS. The GPS software embedded in your wrist watch interprets the incoming signal, identifying the satellite that it came from, where it was located, and the time which it took for the signal to reach the GPS system. Once the receiver has both distance and time the GPS software begins to determine your position.
The intersection point is provided by three satellites and a fourth satellite is used to cross-check if the positioning calculated is accurate. The accuracy also depends upon the synchronization of the atomic clocks in the satellites with the clock in the GPS system.

It is now being used consistently in all walks of human life. The much sought after GPS helps in locating, navigating and tracking as well as keeping a record of the maps and routes for the various locations all set on your wrist.
