New EGNOS satellite contract

The EC has awarded SES a second long-term contract to host an EGNOS overlay payload aboard an Astra spacecraft under construction.

The 2 deals have a combined value of at least €270 (£241 or $392) million.

In the 12 January agreement, SES will place an L-band (GPS L1) navigation payload on its Astra 5B direct-broadcast television satellite, under construction by Astrium and scheduled for launch in mid-2013.

The Astra 5B geostationary satellite will be operated at 31.5° E longitude.

This follows a 2009 contract for an identical navigation payload to be placed on SES’s Sirius 5 satellite, under construction by Space Systems/Loral and scheduled for launch in late 2011. Sirius 5 will operate at 5° E.

The 2 payloads will be the core spaceborne part of the European Geostationary Navigation Overlay Service (EGNOS), which achieved initial operational capability in 2009 (see news). The EGNOS satellites provide ranging signals - like any other GPS satellite - as well as giving differential corrections and integrity info on all GPS satellites in view.

EGNOS is currently provided by a mobile comms satellite operated by Inmarsat and by Europe’s Artemis data-relay satellite. Both are scheduled to be retired in the next 3 years.

Annual service payments will be about €9 million euros per year per satellite - giving a total of €270 million over 15 years.
