AsiaSat 5is aHong Kongcommunications satellite,which is operated by theHong KongbasedAsia Satellite Telecommunications Company(AsiaSat). It is positioned ingeostationary orbitat a longitude of 100.5° East of theGreenwich Meridian,where it replaced theAsiaSat 2satellite.[2]It is used to providefixed satellite services,including broadcasting, telephone and broadbandvery small aperture terminal(VSAT) communications, toAsiaand thePacific Ocean region.[3]
Background
[edit]The launch was originally scheduled to be conducted byLand Launch(SSL-1300LL satellite bus), using aZenit-3SLBlaunch vehicle. The satellite was subsequently re-awarded to ILS after Land Launch were unable to guarantee that the satellite could be launched by August 2009, in order to be in orbit before AsiaSat 2 ceased operations.[4][5]
Satellite description
[edit]Space Systems/Loral (SS/L), announced in May 2005 that it has been chosen by AsiaSat. At launch, AsiaSat 5 had a mass of 3,760 kg (8,290 lb),[6]and was expected to operate for fifteen years. It carries 26C-bandand 14Ku-bandtransponders.[2]
Launch
[edit]AsiaSat 5 was built bySpace Systems/Loral,and is based on theLS-1300XSsatellite bus.[3]It is being launched byInternational Launch Services(ILS), using aProton-Mlaunch vehiclewith aBriz-Mupper stage.The launch was conducted fromSite 200/39at theBaikonur CosmodromeinKazakhstan,at 19:47:33UTCon 11 August 2009. The Briz-M separated from the Proton-M nine minutes and forty one seconds into the flight, and AsiaSat 5 will separate from the Briz-M into ageosynchronous transfer orbit(GTO) nine hours and fifteen minutes after liftoff.[6]It will then raise itself into its finalgeostationary orbit.
