Client
The European Geostationary Navigation Overlay Service (EGNOS) provides European navigation services alongside the American GPS and the Russian-led GLONASS systems.

Challenges
Following two completely separate tenders by the European Commission, SES is supplying the first two commercial payloads for EGNOS. Both tailor-made payloads operate in the L-band to help verify, improve and report on the reliability and accuracy of positioning signals in Europe. In the future, it will also support the European GALILEO navigation system.

Scope
The hosting satellites provide the capability to extend the coverage of the service from Europe to Africa and other neighbouring countries of the EU.

Solution
In addition to the two commercial payloads for EGNOS, SES is supplying ground infrastructure, including fully redundant ground network hosting and two redundant uplink chains. The first EGNOS L-band payload is located on the SES-5 satellite, which launched in the second half of 2012 to 5° East. SES is currently working with the European Commission on the acceptance procedure of the payload. The second payload is hosted on the ASTRA 5B satellite, will launch in the first half of 2014 to 31.5° East.
