A global navigation satellite system (GNSS) provides autonomous geo-spatial positioning with global coverage.A GNSS allows small electronic receivers to determine their location such as longitude, latitude, and altitude to within a few meters using time signals transmitted along a line of sight by radio from satellites in outer space.Receivers on the ground with a fixed position can also be used to calculate the precise time as a reference for scientific experiments.
