The GPS Function
GPS (Global Positioning System) is a space-based satellite navigation system that
provides location and time information anywhere on the earth. It was developed by the
U.S. Department of Defense as a military system. When the GPS receiver acquires
signals from 3 or more (of about 30) GPS satellites orbiting at an altitude of about
20,000 km, it can calculate and display its current position (latitude, longitude, and
altitude) within a tolerance of several meters. In addition, GPS can receive the exact
time from the satellite onboard atomic clock.
