Global Navigation Satellite Systems (GNSS) is the term used to describe satellite navigation systems. This includes GPS, GLONASS (the Russian system), Beidou (the Chinese system), and GALILEO (the system being developed by the European Union).
Each constellation has slightly different designs. For example, they are at different altitudes, and thus have different orbital periods. Secondly, they use different frequencies, although all are L-band.
