SKYM-1
Hybrid Ku-band and R-band Commercial Communications Satellite
FACTS AT A GLANCE
Mission Description
The SKYM-1 spacecraft will carry 24 active Ku-band transponders and 2 active R-Band transponders
providing Direct-to-Home broadcast services to the Mexico, Central America, and Caribbean Regions.
The satellite will be located at 78.8 degrees West Longitude and will produce approximately 5.0 kilowatts
of payload electrical power.
Orbital Sciences Corporation was selected by DIRECTV to build SKY MEXICO -1 (SKYM-1). The SKYM-1
satellite design is based on Orbital’s highly successful, ight-proven, GEOStar-2
be manufactured and tested at Orbital’s state-of-the-art satellite manufacturing facility in Dulles, Virginia.

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.
