Global Navigation Satellite System (GNSS)

The Global Navigation Satellite System (GNSS) is a constellation of satellites orbiting the Earth that can determine the geographic location of a user’s receiver anywhere in the world. It covers all constellations including the US Global Positioning System (GPS), the Russian GLONASS, the European Galileo, the Japanese QZSS and the Chinese BeiDou satellite systems. A receiver will typically track all of the available satellites simultaneously, but only a selection of them will be used to calculate your position. In the future you will hear more about GNSS than GPS.
