Intelsat 11
Hybrid C-band and Ku-band Commercial Communications Satellite for Intelsat
FACTS AT A GLANCE
Mission Description
The Intelsat 11 satellite manufactured for Intelsat carries a hybrid payload. Located at an orbital slot
at 43 degrees West Longitude, the satellite's C-band payload serves the Continental United States
(CONUS), Mexico and South America and the Ku-band payload serves the DIRECTV Latin America
downlink coverage area of Brazil. The Ku-band payload also has uplink capability from the CONUS,
Mexico, Europe, and Northwest and Southeast South America.

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.
