Global Navigation Satellite Systems (GNSS) consists of constellations of Earth-orbiting satellites that provide positioning, navigation, and timing (PNT) information to receivers on the ground. These constellations include GPS, Galileo, GLONASS, Beidou, IRNSS and QZSS, etc. and are used in various applications such as space stations, aviation, maritime, rail, road and mass transit. They also play a critical role in telecommunications, land surveying, law enforcement, emergency response, precision agriculture, mining, finance, and scientific research.
