Thaicom 6

Hybrid C-band and Ku-band Commercial Communications Satellite

FACTS AT A GLANCE

Mission Description

Orbital Sciences Corporation was selected by Thaicom PLC to build their sixth satellite, Thaicom 6. The

Thaicom 6 satellite design is based on Orbital’s highly successful, ight-proven, GEOStar-2™ satellite

platform, and was manufactured and tested at Orbital’s state-of-the-art manufacturing facility in Dulles,

Virginia.

Thaicom 6 carries a hybrid Ku- and C-band payload operates on approximately 3.5 kilowatts of payload

power. The Ku-band payload is comprised of eight active transponders (9 x 36 - MHz Transponder

Equivalent) providing services to Thailand, Laos, Cambodia, and Myanmar. The C-band payload

features 12 active C-band transponders providing services via a regional beam to Southeast Asia and

six active C-band transponders (12 x 36 - MHz TPE) providing services to Africa.

The GEOStar™ Advantage

Orbital’s highly successful Geosynchronous Earth Orbit (GEO) communications satellites are based on

the company’s GEOStar spacecraft platform, which is able to accommodate all types of commercial

communications payloads and is compatible with all major commercial launchers. The company’s

GEOStar product line includes the GEOStar-2 design, which is optimized for smaller satellite missions

that can support up to 5.0 kilowatts of payload power. Orbital has also developed the higher-power

GEOStar-3 spacecraft design, delivering the next increment of payload power for applications between

5.0 and 8.0 kilowatts, allowing Orbital to offer its innovative and reliable satellite design to the

medium-class of communications satellites.
