AsiaSat 5 is aHong Kongcommunications satellite, which is operated by the Hong Kong–basedAsia Satellite Telecommunications Company (AsiaSat). It is positioned ingeostationary orbit at a longitude of 100.5° East of theGreenwich Meridian, where it replaced theAsiaSat 2 satellite.[2] It is used to providefixed satellite services, including broadcasting, telephone and broadbandvery small aperture terminal (VSAT) communications, toAsia and thePacific Ocean region.[3]
The launch was originally scheduled to be conducted byLand Launch (SSL-1300LL satellite bus), using aZenit-3SLB launch 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]
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-band and 14Ku-bandtransponders.[2]
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 vehicle with aBriz-Mupper stage. The launch was conducted fromSite 200/39 at theBaikonur Cosmodrome inKazakhstan, at 19:47:33UTC on 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.
