ViaSat-1 Ka-band Satellite
|
ViaSat uses this spectrum for its Ka-band direct-to-consumer broadband Internet service, under the trade name "exede." The ViaSat-1 satellite was launched from Baikonur on October 19th, 2011, and entered commercial service on January 16th, 2012.
The satellite downlinks and uplinks use both right- and left-hand circular polarizations from a geostationary orbit at 115.1 deg west longitude.
ViaSat-1 has 72 user beams, of which 63 serve the U.S. Nine beams serve Canada.
User terminals utilize a dish of 0.695 m (about 27") maximum diameter, and will uplink using carriers between 625 kHz and 10 MHz wide using max EIRP between 47.2-50.3 dBW. The antennas have transmit gain of about 44 dBi, and receive gain of about 40 dBi. ViaSat is authorized for up to 250,000 such terminals in the continental U.S., operating under the callsign E120026.
The satellite downlink bandwidth is between 52-416 MHz.
As of March 2013, ViaSat claimed 512,000 customers. They have also announced plans for the ViaSat-2 satellite, to be launched in mid-2016, which will have 2.5 times the capacity of ViaSat-1, and will have a single beam that covers the continental U.S., Mexico, most of Canada, portions of Central America and the Caribbean, and the North Atlantic over to the western edge of Europe.
