How GPS Works
Developed by the U.S. military, the global positioning system (GPS) is made up of 24 orbiting satellites.
There are at least four satellites visible at any given time every day. A GPS receiver is designed to locate
and receive data from four of these satellites. These data include the distance to your location from
each of the satellites. Once the distance from each satellite is known, the receiver can calculate and
pinpoint your exact location.
