ViaSat-1 is a communications satellite owned by ViaSat. Launched October 19, 2011 aboard a Proton rocket, it holds the Guinness record for the world's highest capacity communications satellite with a total capacity in excess of 140 Gbit/s, more than all the satellites covering North America combined, at the time of its launch.[2]

ViaSat-1 is capable of two-way communications with small dish antennas at higher speeds and a lower cost-per-bit than any satellite before.[citation needed]

The satellite will be positioned at 115.1 degrees West longitude, with 72 Ka-band spot beams; 63 over the U.S. (Eastern and Western states, Alaska and Hawaii), and nine over Canada.

The Canadian beams are owned by satellite operator Telesat and will be used for the Xplornet broadband service to consumers in rural Canada. The US beams will provide fast Internet access called ExedeSM, ViaSat's satellite Internet service.[3]

ViaSat-1 is part of a new satellite system architecture created by ViaSat Inc. The objective is to create a better satellite broadband user experience,[4] making satellite competitive with DSL and wireless broadband alternatives for the first time.[5]
