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.
