SES-5 GEO Satellite Ensures EGNOS Services for the Long Term

04 September 2015

The European GNSS Agency (GSA) is pleased to announce that after extensive ground and space testing, the SES-5 GEO satellite has entered the EGNOS operational platform broadcasting EGNOS Signal-In-Space (SIS).

A new SES-55 GEO satellite has entered into European Geostationary Navigation Overlay Service (EGNOS), ensuring long-term service and enabling a range of performance improvements. The satellite, which replaces the Inmarsat 4F2, will ensure reliable EGNOS services until 2026.

The satellite will enable a range of performance improvements, including even greater stability during periods of high ionospheric activity.

“SES-5 is the first step of the complete renewal of the EGNOS Space Segment, securing EGNOS services for the next decade and the future transition to dual-frequency, multi-constellation services,” says GSA Executive Director Carlo des Dorides. “It will be completed by the introduction of the ASTRA-5B signals and the procurement of a new EGNOS payload, both planned for 2016.”

Launched in 2009, EGNOS has provided both correction and integrity information on the GPS system, delivering opportunities for Europeans to use the more accurate positioning for improving existing services and developing a wide range of new applications. For example, the EGNOS safety-of-life service enables safer and more flexible landings, including under bad weather conditions and at less well-equipped airports. Services like this will be further enhanced by the entry into service of the SES-55 GEO satellite.
