How does GPS tracking work?

In short and very general 'GPS Tracking' is the process of logging the trail of a location. This location has been calculated by a device using information received from a Global network of Satellites.

The Global Positioning Satellites (GPS) send out information in the general direction of earth, like a radio station emitting a signal, this signal of information is in shorts bursts like a submarine ping.

When the device has received several lots of information from several different satellites it then can calculate its location through triangulation.

This location information can be used immediately and/or stored on the device or sent to another device to be stored. 

We then use this location information to recreate the trail, thus tracking the device by the locations calculated with the GPS information, simply shortened to GPS Tracking.
