Mission Description

The Amazonas 4A spacecraft, built for Hispasat, features 24 Ku-band active transponders to
provide voice, wireless backhaul, internet, and media applications services to South America from
an orbital location at 61 degrees West Longitude. The satellite is based on Orbital's highly successful
GEOStar™-2 spacecraft bus and features two 2.5 x 2.7 meter single shell super elliptical deployable
reflectors.

The contract for Amazonas 4A also includes an option for a second spacecraft to be based on a higher
power Orbital spacecraft bus.

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.
