global navigation satellite system
- Definição1
- Satellite navigation system that provides autonomous geospatial positioning with global coverage. It allows small electronic receivers to determine their location (longitude, latitude, and altitude) to within a few meters using time signals transmitted along a line of sight by radio from satellites.

- Definição2
- 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 form 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.
