EchoStar XVII

EchoStar XVII or EchoStar 17, also known as Jupiter 1,^[2] is an American geostationary high throughput communications satellite which is operated by Hughes Network Systems, a subsidiary of EchoStar. It is positioned in geostationary orbit at a longitude of 107.1° West,^[3] from where it is used for satellite internet access over HughesNet.^[4]

EchoStar XVII was built by Space Systems/Loral,^[5] and is based on the LS-1300 satellite bus.^[2] It measures 8.0 metres (26.2 ft) by 3.2 metres (10 ft) by 3.1 metres (10 ft), with 26.07-meter (85.5 ft) solar arrays which were deployed after launch, and generates a minimum of 16.1 kilowatts of power.^[3] The spacecraft had a mass at liftoff of 6,100 kilograms (13,400 lb), and is expected to operate for fifteen years.^[2] It carries sixty K_a band (NATO K band) transponders which is used to cover North America.^[3]

EchoStar XVII was launched by Arianespace, using an Ariane 5ECA carrier rocket flying from ELA-3 at Kourou. The spacecraft was launched at 21:36 UTC on 5 July 2012.^[6] The MSG-3 weather satellite was launched aboard the same rocket, mounted below EchoStar XVII, which was atop a Sylda 5 adaptor.^[3] The launch successfully placed both satellites into a geosynchronous transfer orbit. EchoStar XVII used its own propulsion system to manoeuvre into a geostationary orbit.^[4]
