The European Space Agency (ESA) is currently completing the final qualification stages of the European Geostationary Navigation Overlay Service (EGNOS) and is in the process of developing the GALILEO system, a self-standing 30 satellite constellation for global satellite navigation. The European GNSS Evolution Program was defined in 2006 by ESA to address the second generation of these systems.[1]
As part of the evolutions considered, three more RIMS are scheduled to be deployed in Agadir (Morrocco), Athens (Greece) and Alexandria (Egypt) providing the extension of EGNOS signal coverage to northern Africa.
Besides, processing improvements are scheduled for the EGNOS signal, including iono algorithm pre-processing fine tuning.
Finally, the deployment of EGNOS v3 is scheduled to cover the Multi-Constellation Regional System (MRS) concept and implement a GPS L5 augmentation service.
GNSS Evolution program
As part of the GNSS Evolution program, ESA called for two parallel studies in the scope of a Multi-constellation Regional System (MRS), that is, the evolution of the EGNOS concept to cope within a multi-constellation environment (Galileo, GPS, others GNSS constellations), and a multi-frequency scenario (GPS L1, L5; Galileo L1, E5a, E5b, E6, etc..).[2]
