EGNOS V3

Improving satellite positioning performance

The European Geostationary Navigation Overlay Service (EGNOS) V3 is the second generation of Europe's Satellite-Based Augmentation System (SBAS). It will improve the accuracy, coverage and reliability of the GPS and Galileo global navigation satellite systems by providing augmentation data which strengthens positioning performance.

EGNOS V3 will also integrate essential safety features for civil aviation, while offering new services for maritime and land users.

Safety of life applications

Featuring three operations centres and more than 44 monitoring stations in Europe and abroad, EGNOS V3 will monitor signals from GPS and Galileo. EGNOS V3 computation centres then generate correctional messages that are broadcast to all users via geostationary satellites. By applying these corrections to signals received from Galileo and GPS, users get improved navigation performance.

This new generation V3 will embed sophisticated security protection against cyber-attacks.

Airbus has been awarded the main contract for the implementation phase of EGNOS V3 from the European Space Agency (ESA) on behalf of the European Commission and EUSPA, and leads an industrial consortium of twenty European companies.

The Airbus team is directly responsible for EGNOS V3 system and performance activities, the development of central processing facilities with improved navigation algorithms, as well as the system performance simulation platform.
