Global Navigation Satellite System (GNSS)

Definition(s):

  GNSS collectively refers to the worldwide positioning, navigation, and timing (PNT) determination capability available from one or more satellite constellations. Each GNSS system employs a constellation of satellites that operate in conjunction with a network of ground stations. Receivers and system integrity monitoring are augmented as necessary to support the required position, navigation, and timing performance for the intended operation.
