Encyclopedia > European Geostationary Navigation Overlay Service
 The European Geostationary Navigation Overlay Service (EGNOS) is a satellite navigation system under development by the European Space Agency, the European Commission and EUROCONTROL. It is intended to supplement the GPS and GLONASS systems by reporting on the reliability and accuracy of the signals. According to specifications, horizontal position accuracy should be better than 7 meters. In practice, the horizontal position accuracy is at the meter level. It will consist of three geostationary satellites and a network of ground stations and was intended to be operational in June 2005, but due to delays the date hwas pushed back to the first quarter of 2006. It is planned as a precursor to the Galileo positioning system. As of july 2006, the service is operational. Satellite navigation systems allow small electronic devices to determine their location (Longitude, Latitude, and Altitude) in within a few metres using time signals transmitted along a line of sight by radio from satellites. ...
