SES-5-EGNOS-sat-O

After extensive ground and space testing, the SES-5 GEO satellite has entered into the European Geostationary Navigation Overlay Service (EGNOS) operational platform, broadcasting EGNOS Signal-In-Space (SIS), according to the European GNSS Agency (GSA). SES-5 — which replaces Inmarsat-4F2 — will ensure reliable EGNOS services until 2026. It has been introduced through EGNOS System Release V241M, which will enable a range of performance improvements.... read more
