Nimiq-5 is a Canadian communications satellite, operated by Telesat Canada as part of its Nimiq fleet of satellites.^[5] It is positioned in geostationary orbit at a longitude of 72.7° West of the Greenwich Meridian.^[6] As of July 2015, EchoStar Corporation leases the satellite's entire capacity to provide high-definition television direct-to-home broadcasting for Dish Network Corporation.^[6][4] When accessed using a multi-satellite receiver such as the VIP722k and a multi-satellite dish/LNB combo, such as the Dish-300, Dish-500, or Dish-Turbo 1000.4, the satellite is referred to by the on-screen diagnostics as Echostar 72 W.^[7]

Spacecraft[edit]

Nimiq-5 was built by Space Systems/Loral, and is based on the LS-1300 satellite bus.^[8] The contract to build it was announced on 4 January 2007.^[9] At launch, it will have a mass of 4,745 kg (10,461 lb),^[10] and is expected to operate for fifteen years. It carries 32 Ku-band transponders frequency designation system.^[8]

Launch[edit]

Nimiq-5 was launched by International Launch Services (ILS), using a Proton-M launch vehicle with a Briz-M upper stage, under a contract signed in April 2007.^[11] The launch was conducted from Site 200/39 at the Baikonur CosmodromeinKazakhstan, at 19:19:19 UTC on 17 September 2009. The Briz-M separated from the Proton-M nine minutes and forty one seconds into the flight and subsequently made five burns before releasing Nimiq-5 into a geosynchronous transfer orbit nine hours and fifteen minutes after liftoff.^[10]
