(*) Protocol defined by ESA.
EDAS, the EGNOS Data Access Service, is the third EGNOS service available to users, after the Open Service and the Safety-of-Life Service. Unlike the other two EGNOS services (SoL and OS), EDAS does not provide its products to the users through the EGNOS Signal-In-Space, but throught Internet. EDAS services are oriented to users in different domains of application such as Location Based Services (LBS), Assisted-GNSS (A-GNSS) concepts, a broad range of services in professional GNSS markets, and related R&D activities.
EGNOS (the European Geostationary Navigation Overlay Service) is the European Satellite-Based Augmentation System (SBAS) that complements the GPS system to improve the accuracy and provides integrity to the signal over most of Europe.
It is Europe's first venture into satellite navigation and a major stepping-stone towards Galileo, Europe's own global satellite navigation system for the future.
ESSP was founded in 2009 by the Air navigation services providers from France (DGAC/DSNA), Germany (DFS), Italy (ENAV)), Portugal (NAV-P), Spain (Aena), Switzerland (skyguide) and UK (NATS) and has for mission the provision of the EGNOS Open Service (OS) and Safety of Life (SoL) Service compliant with ICAO SBAS standards and recommended practices throughout the European Civil Aviation Conference (ECAC) Region.
ESSP is also in charge of the provision of the EDAS Service (EGNOS Data Access Service).
