Orbital KOREASAT 6 - Manual

Communications
Mission Description
Orbital teamed with Thales Alenia Space of France to supply the KOREASAT 6 commercial
communications satellite for KT Corporation of the Republic of Korea. Orbital provided its GEOStar-2™
satellite platform; carried out engineering, manufacturing, integration and final spacecraft testing at
its satellite manufacturing facility located in Dulles, Virginia; and performed launch site operations
in Kourou, French Guiana. Thales Alenia Space was prime contractor for the project and provided
the communications payload. In addition, the team delivered a ground system to support on-orbit
operations of the satellite. Orbital provided six months of on-site support after the satellite was handed
over to the customer.
KOREASAT 6 carries 24 Ku-band channels to provide Fixed Satellite Services (FSS) and six channels
for Direct Broadcast Services (DBS) to the people of Korea. The spacecraft generates 3.4 kilowatts of
payload power and has a 15-year on-orbit mission life. KOREASAT 6 was launched in December 2010
to a final orbital slot at 116 degrees East Longitude.
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.
