EDAS is the EGNOS terrestrial data service and offers ground-based access to EGNOS data in real time and also in a historical FTP archive to the authorised users.

	EDAS provides the opportunity to deliver EGNOS data to users who cannot always view the EGNOS satellites (such as in urban canyons) or to support a variety of other value added services, applications and research programs. EDAS also permits users to access additional data that is not provided by the EGNOS Signal broadcast by the geostationary satellites. The EGNOS EDAS is available since 26 July 2012 <ref name="EDAS Service Definition document">[https://~~www~~.gsc-europa.eu/sites/default/files/~~sites/all/files~~/~~egnos-data-access-service-sdd~~.~~PDF~~ EDAS Service Definition document]</ref>..

	In 2006, the European Commission through the GJU (now superseded by the European GNSS Agency, the GSA) commissioned the EDAS system. EDAS allows any authorized entity to plug into EGNOS to receive the internal data collected, generated and delivered by EGNOS for free. Although the idea of providing GNSS data streams in real time is far from being new, EDAS has some key differentiators, the most important one is probably the service reliability. Other benefits that EDAS brings are the high data rate (1Hz), the dissemination of the EGNOS message broadcast by each GEO satellite and the provision of GLONASS raw measurements. Additionally EDAS provides the raw data of the Ranging and Integrity Monitoring Stations (RIMS) and Navigation Land Earth Stations (NLES).

	EDAS offers ground-based access to EGNOS data, it is the single point of access for the data collected and generated by the EGNOS infrastructure and it represents the terrestrial commercial data service provided by EGNOS.
