The European Commission (EC) is currently specifying the long-term evolution of the European GNSS (EGNSS) Programme, including new services for Galileo and EGNOS:

• The Galileo High Accuracy Service (HAS) will provide free of charge real-time improved user positioning performances with accuracy less than two decimetres (in nominal conditions) through the Galileo signal (E6-B) and by terrestrial means (Internet);

• The next generation of EGNOS will augment GPS and Galileo in the L1 and L5 frequency bands and will extend the service area to the entire landmasses of EU member states.

However, the dissemination over Medium Earth Orbit (MEO) and Geostationary Earth Orbit (GEO) satellites limits operational availability of the signal for end-users in high-latitudes.

The contractor shall analyse cost-effective potential data delivery means alternative to the current EGNOS and Galileo ones.

EGNSS additional dissemination means.
