It will be positioned in [[geostationary orbit]] at a longitude of 100.5° East of the [[Greenwich Meridian]], where it will replace the older [[AsiaSat 2]] spacecraft.<ref name="Fleet">{{cite web|url=http://www.asiasat.com/asiasat/contentView.php?section=65&lang=0|title=AsiaSat 5|work=Satellite Fleet|publisher=AsiaSat|accessdate=2009-08-02}}</ref> It will be used to provide [[fixed satellite services]], including broadcasting, telephone and broadband [[Very small aperture terminal|VSAT]] communications, to [[Asia]] and the [[Pacific Ocean]].<ref name="GSP">{{cite web|url=http://space.skyrocket.de/doc_sdat/asiasat-5.htm|title=AsiaSat 5, 5C|first=Gunter|last=Krebs|publisher=Gunter's Space Page|accessdate=2009-08-02| archiveurl= http://web.archive.org/web/20090627054922/http://space.skyrocket.de/doc_sdat/asiasat-5.htm| archivedate= 27 June 2009 <!--DASHBot-->| deadurl= no}}</ref>▼

AsiaSat 5 was built by [[Space Systems/Loral]], and is based on the [[LS-1300LL]] [[satellite bus]].<ref name="GSP"/> It is being launched by [[International Launch Services]], using a [[Proton-M]] rocket with a [[Briz-M]] upper stage. The launch was conducted from [[Baikonur Cosmodrome Site 200|Site 200/39]] at the [[Baikonur Cosmodrome]] in [[Kazakhstan]], at 19:47 GMT 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]] nine hours and fifteen minutes after liftoff.<ref name="MO">{{cite web|url=http://www.ilslaunch.com/assets/pdf/AsiaSat-5-MO-final.pdf|title=Mission Overview|work=AsiaSat 5|publisher=International Launch Services|accessdate=2009-08-02}}</ref> It will then raise itself into its final geostationary orbit.▼

The launch was originally scheduled to be conducted by [[Land Launch]], using a [[Zenit-3SLB]] carrier rocket. 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.<ref name="Transfer">{{cite web|url=http://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|accessdate=2009-08-11|publisher=Reuters}}</ref><ref name="SFN-W2A">{{cite web|url=http://www.spaceflightnow.com/proton/w2a/|title=Multi-tasking satellite deployed by 50th ILS Proton|date=2009-04-03|first=Stephen|last=Clark|accessdate=2009-08-11}}</ref>▼
