Description:

• KA-SAT, the first High Throughput Satellite (HTS) in Europe, marks a new generation of multi-spotbeam high-capacity satellites. Built for Eutelsat by EADS Astrium, KA-SAT’s revolutionary concept is based on a payload with 82 narrow Ka-band spotbeams connected to a network of ten ground stations. This configuration enables frequencies to be reused 20 times and takes total throughput to beyond 70 Gbps.
• The ground network uses ViaSat’s SurfBeam® technology, similar to the solution powering broadband connectivity for almost 450,000 satellite homes in North America. The combination of KA-SAT’s exceptional capacity and ViaSat’s SurfBeam® technology will make it possible to deliver Internet connectivity for more than one million homes, at speeds comparable to ADSL.
• KA-SAT will also respond to professional requirements for higher volume and bandwidth for applications ranging from private networks and Internet backhaul to machine-to-machine connectivity. For this type of heavier bandwidth use, the Tooway™ terminal can deliver speeds of up to 40Mbps downstream and 10 Mbps upstream.

Mission details:

• First satellite with exclusively Ka-band communications payload.
• Another Proton-M was launched on Dec 26, 2010 carrying the commercial KA-SAT payload for Eutelsat. This time Proton-M was successful and the Briz-M stage made 5 burns from a -496 x 171 km injection orbit to a deployment orbit of 3704 x 35763 km x 24.6 deg.
• KA-SAT is an Astrium Eurostar 3000 satellite with a launch mass of 6150 kg and a dry mass of 3200 kg, providing broadband services in the Ka-band with 80 spot beams.
