Global Positioning System
Global Positioning System, GPS is satellite navigation system used to determine the ground position of
an object. GPS technology was first used by the United States military in the 1960s and expanded into
civilian use over the next few decades. Today, GPS receivers are included in
many commercial products, such as automobiles, smartphones, exercise
watches, and GIS devices.
The GPS System included 24 satellites deployed in space about 12,000 miles
(19,300 kilometers) above the earth’s surface. They orbit the earth once every
12 hours at an extremely fast pace of roughly 7,000 miles per hour (11,200
kilometers per hour). The satellites are evenly spread out so that four satellites
are accessible via direct line-of-sight from anywhere on the globe.
