THAICOM 6 is colocated with Thaicom 5 at 78.5 degrees East, in geostationary orbit. The total cost for the satellite is {{US$|160 million}}. OverviewTHAICOM 6 is a 3-axis stabilized spacecraft, carrying 18 active C-band transponders and 8 active Ku-band transponders. The Ku-band transponders are both addressed as well as beam-switched to broadband. THAICOM 6 provides communication service to Southeast Asia, Africa and Madagascar[3] with its primary role being DTH service for Thailand.[4]{{update after|2014|2|3}} LaunchThe spacecraft was launched on January 6, 2014, by SpaceX on a Falcon 9 v1.1 launch vehicle. The payload was delivered by SpaceX to a {{convert|90000|km|mi|sp=us}}-apogee supersynchronous elliptical transfer orbit that will later be reduced by the satellite builder Orbital Sciences Corporation to an approximately {{convert|35800|km|mi|sp=us}} circular geostationary orbit. The supersynchronous transfer orbit enables an inclination plane change with a lower expenditure of propellant by the satellite's kick motor.[5]` This launch was SpaceX's second transport of a payload to a Geostationary transfer orbit.[6][7] Both the SES-8 SpaceX launch before this one and THAICOM 6 utilized a supersynchronous transfer orbit, but Thaicom 6 was at a somewhat greater apogee than that used for SES-8.[5] The Falcon 9 upper stage used to launch THAICOM 6 was left in a decaying elliptical low-Earth orbit which decayed over time and, on 28 May 2014, re-entered the atmosphere and burned up.[8] See also{{Portal|Spaceflight}}
