EGNOS V3 on its way

A contract has been signed for the next generation of the European Geostationary Navigation Overlay Service.

The contract was signed on 26 January at ESA’s Technical Centre in the Netherlands for the next generation of the European Geostationary Navigation Overlay Service, EGNOS V3, planned to enter service in 2025 and replacing V2, which entered service in 2011.

ESA’s Director of Navigation signed the contract with the Senior Vice President of Airbus Defence and Space in the presence of senior managers of the European Global Navigation Satellite System Agency (GSA) and the European Commission. Airbus explains that the 6.5-year contract will see ~100 people and 20 subcontractors working on the system.

The improved version of the service will cover operational Galileo as well as upgraded GPS services, claiming by ESA to be 'The first such regional satellite augmentation system worldwide to employ dual frequency GPS and Galileo signals.' By 2023, a single-frequency version will be available to replace the current V2, and 18 months later the final V3 - in dual frequency - should be delivered.

EGNOS currently has almost 50 ground stations deployed over Europe, Africa and North America, 2 Master Control Centres located near Rome and Madrid, and a System Operation Support Centre in Toulouse. To transmit correction/integrity data to users, it uses 2 geostationary satellites at 15.5ºW and 31.5ºE with a 3rd at 5ºE under test.

EGNOS 2 is compatible with other GPS local augmentation systems - the US Wide Area Augmentation System (WAAS), Japan's Multi-functional Satellite Augmentation System (MSAS) and India's GPS Aided GEO Augmented Navigation (GAGAN). EGNOS 3 claims that it will remain compatible with legacy equipment designed to use any of these older overlays.
