The European Satellite Navigation System (GALILEO), an initiative launched by the European Commission and the European Space Agency, will be a global navigation satellite system, owned by the European Union providing highly accurate, guaranteed global positioning services under civilian control. The Galileo Open Services signal will be interoperable with the GPS civil signal, as well as with GLONASS.
The European Geostationary Navigation Overlay Service (EGNOS) is a Satellite-based Augmentation System (SBAS) providing service for safety critical applications in Europe. As a first element of European GNSS capabilities, EGNOS will be integrated in the GALILEO programme.
