European Geostationary Navigation Overlay Service: EGNOS
The European Geostationary Navigation Overlay Service (EGNOS) is Europe’s first venture into satellite navigation. It augments the two military satellite navigation systems now operating, the US GPS and Russian GLONASS systems. It makes them suitable for safety critical applications, such as flying aircraft, or navigating ships, through narrow channels.
Consisting of three geostationary satellites and a network of ground stations, EGNOS achieves its aim by transmitting a signal containing information on the reliability, and accuracy of the positioning signals sent out by the Global Positioning System (GPS) and the Global Orbiting Navigation Satellite System (GLONASS). It allows users in Europe and beyond, to determine their position to within 2 metres, compared with about 20 metres for GPS and GLONASS alone.
EGNOS is a joint project of the European Space Agency (ESA), the European Commission (EC) and Eurocontrol, the European Organisation for the Safety of Air Navigation. It is Europe’s first activity in the field of Global Navigation Satellite Systems (GNSS), and is a precursor to GALILEO, the full global satellite navigation system, under development in Europe.
