The European GNSS Agency (GSA) announced on 2 September that after extensive ground and space testing, SES-5 GEO satellite has now entered into European Geostationary Navigation Overlay Service (EGNOS) operational platform broadcasting EGNOS Signal-In-Space (SIS).

EGNOS is operated by the European Satellite Services Provider (ESSP), under contract by the GSA on behalf of the European Commission. 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. In particular, EGNOS will offer even greater stability during periods of high ionospheric activity.
