EchoStar XVII or EchoStar 17, also known as Jupiter 1,[1] 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,[2] from where it is used for satellite internet access over HughesNet.[3]

EchoStar XVII was built by Space Systems/Loral,[4] and is based on the LS-1300 satellite bus.[1] It measures Шаблон:Convert by Шаблон:Convert by Шаблон:Convert, with Шаблон:Convert solar arrays which were deployed after launch, and generates a minimum of 16.1 kilowatts of power.[2] The spacecraft had a mass at liftoff of Шаблон:Convert, and is expected to operate for fifteen years.[1] It carries sixty Шаблон:Ka band (NATO K band) transponders which is used to cover North America.[2]

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.[5] The MSG-3 weather satellite was launched aboard the same rocket, mounted below EchoStar XVII, which was atop a Sylda 5 adaptor.[2] The launch successfully placed both satellites into a geosynchronous transfer orbit. EchoStar XVII used its own propulsion system to manoeuvre into a geostationary orbit.[3]
