Hybrid C-band and Ku-band Commercial Communications Satellite

FACTS AT A GLANCE

Mission Description

Orbital was selected by the Boeing Company to provide the Fixed Satellite Services (FSS) segment

of the Mexsat satellite system for the Federal Government of Mexico. The Mexsat system is a three

satellite system consisting of two Mobile Satellite Services (MSS) spacecraft designed and built by

Boeing (Mexsat Centenario and Mexsat Morelos 3) and one FSS satellite, Mexsat Bicentenario,

designed and built by Orbital.

™

Mexsat Bicentenario is based on Orbital’s GEOStar-2

kilowatts of payload power and carries 12 active extended Ku-band and 12 active extended C-band

transponders. The spacecraft provides communications services to Mexico and its surrounding waters

from the 114.9 degrees West Longitude orbital slot. In addition to the Mexsat Bicentenario spacecraft,

Orbital also provided the FSS ground segment, including the satellite command and control ground

equipment and software as well as training and operational documentation.

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.
