Global Positioning System (GPS)
The Global Positioning System (GPS) is a space-based global navigation satellite system
(GNSS) that provides location and time information in all weather, anywhere on or near the
Earth, where there is an unobstructed line of sight to four or more GPS satellites. It is
maintained by the United States government and is freely accessible by anyone with a GPS
receiver. The GPS project was developed in1973 to overcome the limitations of previous
navigation systems , integrating ideas from several predecessors, including a number of
classified engineering design studies from the 1960s. GPS was created and realized by the
U.S Department of Defense (USDOD) and was originally run with 24 satellites. It became
fully operational in 1994.
