GPS can be used for cartography, forestry, mineral exploration, wildlife habitation management, monitoring the movement of people and things and bringing precise timing to the world.

GPS has applications beyond navigation and location determination. Before its civilian applications, GPS was used to provide all-weather round-the-clock navigation capabilities for military ground, sea, and air forces. It was originally called NAVSTAR (Navigation System with Timing and Ranging). GPS was developed and is operated by the U.S. By using four satellites, GPS can also determine altitude. By using three satellites, GPS can calculate the longitude and latitude of the receiver based on where the three spheres intersect. By knowing how far away a satellite is, the receiver knows that it is located somewhere on the surface of an imaginary sphere centered at the satellite. As each signal travels at the speed of light, the longer it takes the receiver to get the signal, the farther away the satellite is. Based on this information the receivers know how long it takes for the signal to reach the receiver on earth. The satellites are equipped with atomic clocks that are precise to within a billionth of a second. This video shows how to download data from a GPS (Garmin etrex 12XL) to a computer for further processing, e.g. The GPS satellites continuously transmit digital radio signals that contain data on the satellites location and the exact time to the earth-bound receivers. The satellites orbit the earth at approximately 12,000 miles above the surface and make two complete orbits every 24 hours.
