The Global Positioning System (GPS) consists of NAVSTAR satellites in earth orbit that send signals to receivers on land, sea, or in the air. The system became operational in 1978. Its military usefulness was demonstrated during Operation Desert Storm (1991), when coalition troops with receivers were able to navigate quickly and with great precision in the relatively featureless desert, thus having a significant tactical advantage over Iraqi forces.
