ViaSat 1

ViaSat 1 is a commercial communication satellite of the U.S. company Viasat.

He was taken on October 19, 2011 at 20.49 clock CEST by a Proton -M rocket from the Baikonur launch site in a geostationary orbit. In this case, after removal of the first three stages of the launch vehicle took over the upper Briz- M the bullet in the geostationary orbit. Through five stages of combustion upper stage of the satellite reached its initial orbit of about 180 km altitude and an inclination of 51.5 degrees to a Geotransferbahn 2360-35785 kilometers at 30.4 degrees, from which it pivots into its final position at 115 ° West. ViaSat 1 is 6.74 with t -off mass, the heaviest payload that was brought to Geotransferorbit with the combination Proton-M/Bris-M.

The three -axis stabilized satellite with 72 Ka-band transponders ( 63 for the USA and nine for Canada) equipped and is on the position of 115 degrees West from 75 % of the U.S. and the most populous areas of Alaska, Hawaii and Canada with telecommunications services / TV / Internet supply. With a data transfer capacity of up to 140 gigabits of data per second, it is currently the world's most powerful communications satellite. The ViaSat Incorporation partners for the operation of the satellite with SS / L, Telesat and Eutelsat to ensure the operation of the satellite and to market its possibilities. So Telesat Canada takes on the telemetry, the tracking and control of the satellite and represents the position reserved for them at 115 ° West available. Eutelsat uses its extensive network to market broadband services ViaSat for telecommunications, Internet services and television. The satellite was built based on the LS -1300 satellite bus of Space Systems / Loral (USA / Canada) and has a design life of 15 years.
