The Global Position System or GPS is a space-based global navigation satellite system that provides reliable location and time information anywhere on the Earth. The system works in all weather and at all times anywhere on or near the Earth where there is a line of site to four or more GPS satellites. Established in 1973, the GPS system was created by the United States Department of Defense and was originally based on and run with 24 satellites. |
