The EGNOS Data Access Service 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
- EDAS is also providing “Differential GNSS (DGNSS) corrections and RTK (Real Time Kinematic) messages for the EGNOS stations allowing users implementing advanced positioning techniques.”
The EDAS Service is provided by ESSP (EGNOS Service Provider) under a contract with the European GNSS Agency.
