Hybrid C-band and Ku-band Commercial Communications Satellite
FACTS AT A GLANCE
Mission Description
Under a contract with The Ministry of Communications and Information Technologies of the Republic
of Azerbaijan (the Ministry), Orbital designed and built the Azerspace/Africasat-1a commercial
communications satellite. Based on Orbital’s ight-proven GEOStar-2™ platform, the hybrid C- and
Ku-band satellite generates approximately ve kilowatts of payload power and carries 36 active
Europe, and Africa from an orbital location at 46 degrees East Longitude through an arrangement
between the Ministry and Measat of Malaysia, which owns the rights to the orbital slot.
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.
