Rent this space - GPS - The U.S. governments military/economic control grid The Global Positioning System (GPS) is a space-based radio-navigation system consisting of a constellation of satellites and a network of ground stations used for monitoring and control. A minimum of 24 GPS satellites orbit the Earth at an altitude of approximately 11,000 miles providing users with accurate information on position, velocity, and time anywhere in the world and in all weather conditions. GPS is operated and maintained by the Department of Defense (DoD). The Interagency GPS Executive Board (IGEB) manages GPS, while the U.S. Coast Guard acts as the civil interface to the public for GPS matters. The Federal Aviation Administration is investigating and applying the use of GPS as it pertains to aviation. faa National Airspace system The objective of NAS Implementation is to develop the operational infrastructure to support the certification process for satellite navigation and provide the technical basis for the development of GPS operational procedures for all phases of flight. NAS Implementation communicates and cooperates with numerous governmental and non-governmental agencies to pave the way for a smooth transition to satellite navigation. site Global Positioning System - History The launch of the Sputnik satellite in 1957 was actually the beginning of GPS. Scientists studying the orbit of the satellite realized they could track the satellite by its radio signal. This in turn would mean that a person on earth could obtain his position on the globe if he could read the signal from the satellite in conjunction with knowing the exact orbit of the satellite. Mohawk Historical Timeline of Radionavigation Systems History of GPS The Global Positioning System (GPS) program began in 1973 as a joint United States Air Force, Navy, Marine Corps, and Defense Mapping Agency (DMA) effort. The goal was development of a space-based, highly accurate navigation system. The enterprise has since gained the interest of the U.S. Army to become a full Department of Defense initiative. GPS achieved full operational capability with a complete constellation of satellites in 1994. arpower.maxwell.afmil
