KA-SAT high-throughput satellite orbited by ILS Proton

The KA-SAT satellite of Eutelsat Communications has been successfully lofted into orbit by a Proton Breeze M rocket supplied by ILS.

KA-SAT bietet mit 82 Spotbeams sehr große Datenraten für Europa und den Mittelmeerraum (Zeichnung: Astrium).  


Lift-off of Eutelsat’s 6.1 tonne satellite took place on 26 December at 21.51 GMT (22.51 CET). After a 9-hour 12-minute flight, the launcher released KA-SAT into geosynchronous transfer orbit. Acquisition of the satellite’s telemetry signal by Eutelsat’s control centre at the Rambouillet teleport, and the partial deployment of the solar arrays have already been successfully completed.

Michel de Rosen, Eutelsat CEO, commented after successful completion of the first satellite manoeuvres: “KA-SAT will be the cornerstone of a breakthrough infrastructure deployed by Eutelsat for users across Europe and the Mediterranean Basin. By combining a satellite equipped with more than 80 spotbeams and a network of ground stations, this new programme will deliver more capacity than any other satellite programme deployed worldwide. These new resources will in particular benefit Internet Service Providers, enabling them to extend broadband to consumers and enterprises in areas unserved by terrestrial networks. KA-SAT will also consolidate Eutelsat’s Professional Data Network activity.”

Built for Eutelsat by Astrium using the Eurostar E3000 platform, KA-SAT ushers in a new generation of multi-spotbeam satellites. Its revolutionary concept is based on a payload with 82 narrow spotbeams connected to 10 ground stations. This configuration enables frequencies to be reused 20 times and takes total throughput beyond 70 Gbps. The ground network will use ViaSat’s SurfBeam technology, similar to the solution already powering broadband connectivity for almost 450,000 satellite homes in North America.

KA-SAT will in particular boost to up to 10 Mbps the speeds of Eutelsat’s Tooway consumer broadband service, which has been operated since 2008 by its Skylogic affiliate. Tooway satellite antennas equipped with dual feeds will be able to benefit from broadband connectivity via KA-SAT and broadcast services delivered by satellites located up to 10 degrees from Ka-SAT’s 9° East location.

Once the satellite is on station at 9° East, it will undergo a series of in-orbit tests. This will be followed by the final phase of integrated validation of the satellite and ground stations before commercial entry into service, which is planned for end May 2011.
