Ekspress-AMU1(Russian:Экспресс-АМУ1), also known asEutelsat 36C,is ageostationarycommunications satelliteoperated byRussian Satellite Communications Company(RSCC) and designed and manufactured byAirbus Defence and Spaceon theEurostar-3000satellite busfor itsEkspress constellation.[1]It massed 5,892 kg (12,990 lb) at launch, had a power production capacity of 15kWand a 15-year design life.[2]Its payload is composed of 61Ku-bandand 10Ka-bandtransponders.[3][4]
Eutelsat 36C
[edit]Eutelsatleased much of its capacitybroadcastingandInternet service providerfor Russia andSub-Saharan Africa,and positioned it in the 36° East under theEutelsat 36Cdesignation.[5]It is part of the Ekspress constellation of RSCC.[6]
History
[edit]On 2 November 2012, Russian Satellite Communications Company (RSCC) and EUTELSAT announced a 15-year agreement to lease capacity on two satellites to be launched in 2013 and 2015. It would be used for broadcasting and IP services and was valued at 300 millioneuro.The first satellite wasEkspress-AT2,already on order, and the second wasEkspress-AMU1,which construction was to be bid later that year.[5]
During 2012, RSCC organized a competition amongEADS Astrium(later Airbus Defense and Space),Thales Alenia Space,MacDonald, Dettwiler and Associates(MDA) andJSC Information Satellite Systems(ISS Reshetnev) to build Ekspress-AMU1. EUTELSAT participated from the selection committee since they intended to lease capacity on board the satellite.[2]
In May 2013, Airbus announced that it had been awarded a contract by RSCC to build Ekspress-AMU1. Also known as EUTELSAT 36C, it would be the follow-up ofEutelsat 36Aat the 36° East. Based on the Eurostar-3000 it would mass around 5,892 kg (12,990 lb) at launch, have an end of life power production of 15 kW and a design life of 15 years. It was expected to be launched by aProton-Min 2015.[7]Airbus bid, while slightly more expensive than Thales, promised to deliver the satellite seven months earlier.[2]
Launch
[edit]By early 2015, the satellite was planned for a September or October 2015 launch, but the satellite was delivered to the launch site inBaikonuron 12 November 2015.[2][8]The launch was then set for 23 December 2015, but weather conditions required a day delay. On 24 December 2015, at 21:31:19UTC,aProton-M/Briz-Msuccessfully launched fromSite 200/39.[2][9][10]
Mission
[edit]On 1 January 2016, RSCC announced that Ekspress-AMU1 had reached thegeostationary orbit.[11]On 10 February 2016, signals from EUTELSAT 36A were switched to Ekspress-AMU1 marking the final commissioning of the satellite into service.[12]
