Communications

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

reectors.

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.
