ViaSat 2 is a commercial communication satellite from ViaSat .
He was born on June 1, 2017 at 23:45 UTC with a 5 Ariane - carrier rocket from the rocket launch site Guiana Space Center (together with Eutelsat 172B ) into a geostationary brought orbit.
The three-axis stabilized satellite is Ka-band - transponders equipped and will supply from position 70 ° West of North and Central America and the Caribbean, and air and sea routes in the Atlantic Ocean between North America and Europe with communication capacities of up to 300 Gbps. It was based on the satellite bus BSS 702HP of Boeing built and has a design life exceeding 14 years. Boeing was commissioned for $ 625 million after the company prevailed against Lockheed Martin in a bidding competition. Space Systems / Loral (who had built ViaSat 1 ) no longer wanted to commission ViaSat after patent disputes.
Because of a mechanical antenna defect, ViaSat 2 did not achieve the planned data throughput . Viasat received insurance compensation for this.
