Satellite Navigation (GNSS)

Satellite navigation refers to using satellite systems to provide the position and timing of the user on the Earth. The major Global Navigation Satellite Systems (GNSS) are GPS (USA), GLONASS (Russia), Galileo (EU), BeiDou (China), and Regional Systems such as NavIC (India), QZSS (Japan), KPS (South Korea)
