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. GNSS is the broader term that includes all constellations like GPS, Galileo, GLONASS, Beidou and QZSS. GNSS is used in various applications such as space stations, aviation, maritime, rail, road and mass transit, positioning, navigation, and timing (PNT) play a critical role in telecommunications, land surveying, law enforcement, emergency response, precision agriculture, mining, finance, and scientific research.
