AsiaSat 5 is a Hong Kong communications satellite, which is operated by the Hong Kong–based Asia Satellite Telecommunications Company (AsiaSat). It is positioned in geostationary orbit at a longitude of 100.5° East of the Greenwich Meridian, where it replaced the AsiaSat 2 satellite.{{cite web|url=https://www.asiasat.com/satellite-fleet/asiasat-5 |title=Satellite Fleet - AsiaSat 5|publisher=AsiaSat|access-date=5 May 2021}} It is used to provide fixed satellite services, including broadcasting, telephone and broadband very small aperture terminal (VSAT) communications, to Asia and the Pacific Ocean region.{{cite web|url=http://space.skyrocket.de/doc_sdat/asiasat-5.htm|title=AsiaSat 5, 7 / Thaicom 6A|first=Gunter|last=Krebs |publisher=Gunter's Space Page|date=11 December 2017|access-date=5 May 2021}}
Background
The launch was originally scheduled to be conducted by Land Launch (SSL-1300LL satellite bus), using a Zenit-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.{{cite web |url=https://www.reuters.com/article/pressRelease/idUS120388+15-Jun-2009+BW20090615|title=ILS Announces 9 New Proton Missions in First Half of 2009|date=2009-06-15|access-date=5 May 2021|work=Reuters |url-status=dead|archive-url=https://web.archive.org/web/20160305111533/http://www.reuters.com/article/idUS120388+15-Jun-2009+BW20090615|archive-date=March 5, 2016}}{{cite web |url=http://www.spaceflightnow.com/proton/w2a/|title=Multi-tasking satellite deployed by 50th ILS Proton|first=Stephen|last=Clark|publisher=Spaceflight Now|date=2009-04-03|access-date=2009-08-11}}
Satellite description
Space Systems/Loral (SS/L), announced in May 2005 that it has been chosen by AsiaSat. At launch, AsiaSat 5 had a mass of {{cvt|3760|kg}}, and was expected to operate for fifteen years. It carries 26 C-band and 14 Ku-band transponders.
Launch
AsiaSat 5 was built by Space Systems/Loral, and is based on the LS-1300XS satellite bus. It is being launched by International Launch Services (ILS), using a Proton-M launch vehicle with a Briz-M upper stage. The launch was conducted from Site 200/39 at the Baikonur Cosmodrome in Kazakhstan, at 19:47:33 UTC 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 a geosynchronous transfer orbit (GTO) nine hours and fifteen minutes after liftoff.{{cite web|url=http://www.ilslaunch.com/assets/pdf/AsiaSat-5-MO-final.pdf |title=Mission Overview - AsiaSat 5|publisher=International Launch Services|access-date=2009-08-02}} It will then raise itself into its final geostationary orbit.
