What is EGNOS?

EGNOS is Europe's first venture into satellite navigation. EGNOS is a Satellite Based Augmentation System (SBAS), which provides corrections and integrity information to GPS signals. It uses a set of monitoring stations to receive GPS signals and estimates their errors. Finally, differential corrections are transmitted to the users by geostationary satellites.  EGNOS makes existing satellite navigation signals suitable for safety critical applications such as flying aircraft or navigating ships through narrow channels. EGNOS has been certified for civil aviation since 2011.

EGNOS increases the accuracy of existing satellite positioning signals from GPS while providing a crucial ‘integrity message', informing users in the event of GPS signal problems. It also transmits an extremely accurate universal time signal.
