The KA-SAT satellite of Eutelsat Communications has been successfully lofted into orbit by a Proton Breeze M rocket supplied by International Launch Services. Built for Eutelsat by Astrium using the Eurostar E3000 platform, the KA-SAT is a new generation of multi-spotbeam satellite. Its 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 70G bps. The company said the combination of KA-SAT's capacity and ViaSat's SurfBeam technology will make it possible to deliver Internet connectivity for more than 1 million homes, at speeds comparable to ADSL.
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. Lift-off of the 6.1-ton satellite took place on the evening of Dec. 26. 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 center at the Rambouillet teleport and the partial deployment of the solar arrays have already been successfully completed," a company statement said.
