Thaicom 6 is a Thai television satellite of the Thaicom series, to be operated by Thaicom Public Company Limited (formerly Shin Satellite Public Company Limited), a subsidiary of Shin Corporation headquartered in Bangkok, Thailand. Thaicom 6 will be colocated with Thaicom 5 at 78.5 degrees East, ("Hot Bird" position), in geostationary orbit. The total cost for the satellite is US$160 million.

Overview[edit]

Thaicom 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. The satellite will provide communication service to Southeast Asia, Africa and Madagascar[3] with its primary role being DTH service for Thailand.[1][dated info]

Launch[edit]

The 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 90,000 kilometers (56,000 mi)-apogee supersynchronous elliptical transfer orbit that will later be reduced by the satellite builder Orbcom to an approximately 35,800 kilometers (22,200 mi) circular geostationary orbit. The supersynchronous transfer orbit enables an inclination plane change with a lower expenditure of propellant by the satellite's kick motor.[4]`

This launch was SpaceX' second transport of a payload to a Geostationary transfer orbit.[5][6] 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.[4]

The Falcon 9 upper stage used to launch Thaicom 6 was left in a decaying elliptical low-Earth orbit which, by September 2013, had decayed and re-entered the atmosphere.[7]
