Data Access Service

Data Access Service

The EGNOS Data Access Service (EDAS) allows users to plug into EGNOS to receive data collected, generated, and delivered by Europe’s first satellite navigation system. It provides the opportunity for service providers to deliver EGNOS data to those who may not always be covered by EGNOS satellites such as when surrounded by tall buildings. It can also benefit a variety of other services, applications, and research programs.

EDAS is the single point of access for the data collected and generated by the EGNOS infrastructure which is composed of ground stations (currently 40) distributed over Europe and North Africa. The main types of data provided by EDAS are:

  • Raw GPS, GLONASS and EGNOS GEO observations and navigation data collected by the entire network of Ranging and Integrity Monitoring Stations (RIMS) and Navigation Land Earth Stations (NLES)
  • EGNOS augmentation messages, as normally received by users via the EGNOS Geostationary satellites

The EDAS Service is provided by ESSP (EGNOS Service Provider) under a contract with the European GNSS Agency.


The EGNOS Helpdesk is the main place for users to register, ask questions about the status of EGNOS services and performances, and consult the EDAS Service Definition Document (EDAS SDD). This document can also be found below.
