global navigation satellite systems

global navigation satellite systems (GNSS)

An “umbrella” term adopted by the International Civil Aviation Organization (ICAO) to encompass any independent satellite navigation system used by a pilot to perform onboard position determinations from the satellite data. GNSS means any navigation system that satisfies stated international navigational requirements using satellite technology. A complete global navigation satellite system may include satellites provided by various states and commercial groups and be complemented by ground systems used to augment and monitor the satellites.
