With a proven throughput of 134 Gbps (giga-bits per second), the ViaSat-1 communications satellite is the highest-capacity communications satellite. Launched from Baikonur Cosmodrome, Kazakhstan, on 19 October 2011 on board a Proton Breeze M rocket, the satellite is in geostationary orbit above North America at 115.1° West longitude. Using 72 spot beams in total (63 over continental USA, Alaska and Hawaii, and 9 over Canada), the satellite provides broadband internet service coverage and general communications. Weighing a total of 6,740 kg (14,860 lb), the satellite is expected to have a 15-year operational life. At the time of launch, this single satellite possessed greater capacity than all of the other satellites covering North America added together.
