What Is GPS ?

In 1974 the USA Department of Defense set about developing a Global Positioning

System (GPS), a constellation of 24 satellites that Orbits 12,000 miles above the Earth.

Using triangulation of signals from four of the satellites, a receiving unit on earth can

pinpoint its current location to within a few meters. A GPS device receive the data,

then convert the longitude, latitude, and altitude (LLA) data into a location point.

Position and navigation information is vital to a wide range of professional and

recreational activities covering surveying, search and rescue, tracking, hiking,

navigating, and so forth.
