European Geostationary Navigation Overlay Service

EU

The European Geostationary Navigation Overlay Service (EGNOS) is Europe's regional satellite-based augmentation system (SBAS), enhancing the accuracy and reliability of global navigation satellite systems (GNSS) like GPS and, in the future, Galileo. Developed by the European Space Agency (ESA) and Eurocontrol on behalf of the European Commission, EGNOS provides corrections and integrity information to GNSS signals, particularly for safety-of-life applications like aviation, maritime, and land navigation. Key services include the Open Service (OS) for improved positioning accuracy, the Safety of Life (SoL) service for critical applications, and the EGNOS Data Access Service (EDAS) for commercial users. EUSPA manages EGNOS operations.
