Galileo and EGNOS

Briefing 24-01-2018

Galileo and the European geostationary navigation overlay service (EGNOS) are two satellite navigation systems under civil control. Galileo is an autonomous global navigation satellite system consisting of a constellation of satellites and a global network of ground stations. EGNOS is a regional satellite navigation system that monitors, corrects and improves the accuracy of open signals emitted by existing global satellite navigation systems (GPS, Glonass). Galileo and EGNOS are infrastructures owned by the European Union, which were conceived in close cooperation with the European Space Agency. They guarantee Europe independent access to a reliable positioning satellite signal, allowing more accuracy than that offered by other accessible systems.
