This has to do with using satellite tracking in getting the location of anything in the world. The satellite can go round the earth twice a day. It travels as fast as 12, 000miles. These satellites weigh as much as 4000pounds and are located just above the earth. The tracking is done through the orbiting of the satellite around the earth. GPS actually means Global Positioning System.
Most people are used to GPS tracking for cars, but it is possible to use it to track anything that actually has the right device that can send a signal. Only four of these satellites can be seen. When the GPS is initiated, it sends a signal to one of these four satellites, and the satellite sends the information back.
