ESA, Thales Alenia Space Sign Contract to Upgrade EGNOS
The European Space Agency (ESA) has signed a contract with Thales Alenia Space for an upgrade of EGNOS, Europe’s satellite-based augmentation system (SBAS).
Designed by ESA and being exploited by Europe’s GNSS Agency (GSA) the European Geostationary Navigation Overlay Service (EGNOS) improves the precision of U.S. GPS signals over most of the European territory, while also providing continuous and reliable updates on the “integrity” of these GPS signals.
