GNSS
Global Navigation Satellite System (GNSS) refers to the constellation of satellites which transmit positioning and timing data to earth. The Global Positioning System (GPS) is an example of a GNSS.
Australia is committed to the adoption of GNSS to enhance safety and efficiency in Australia's airspace, in line with ICAO Assembly Resolution A37–11. GNSS is used to support ADS-B, en route, terminal and non-precision approach navigation capability.
