Global Navigation Satellite System (GNSS)
The Global Navigation Satellite System (GNSS) is a satellite system that is used to pinpoint the geographic location of a user's receiver anywhere in the world. The GNSS network consists of a range of satellites that use microwave signals that are transmitted to GPS devices to give information on location, vehicle speed, time and direction. The most well-known GNSS is the United States' Global Positioning System (GPS), but other systems include the Russian GLONASS, the European Union's Galileo, and China's BeiDou Navigation Satellite System. These systems are critical for the functionality of numerous applications in aerospace engineering, such as navigation and guidance systems for aircraft, spacecraft, and unmanned aerial vehicles (UAVs). They also play a crucial role in various other fields like meteorology, earth science, and telecommunications.
