Our mission

The ESSP mission is 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).




For any inquiry about EGNOS, its operations and its signal status, please contact our Helpdesk


Access conditions to the different EGNOS services are described in the OS, SoL and EDAS Service Definition Documents (SDD).


Temporary amendments to the SDDs are also available as Service Notices.
