Satellite Navigation System


A satellite navigation system is a system of satellites that provide autonomous geo-spatial positioning with global coverage. These systems use signals from satellites to determine the location of an aircraft, as well as its speed and direction. The most well-known satellite navigation system is the Global Positioning System (GPS), which is operated by the United States government. Other satellite navigation systems include the Russian GLONASS, the European Galileo, and the Chinese BeiDou. Satellite navigation systems are used extensively in aviation for navigation, approach and landing procedures, and for tracking aircraft in flight.
