MEXSAT-3

MEXSAT-3

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-1 & MEXSAT-2) and one FSS satellite, MEXSAT-3, designed and built by Orbital.

Based on Orbital’s STAR-2 platform, MEXSAT-3 will generate approximately 3.5 kilowatts of payload power and carry 12 active extended Ku-band and 12 active extended C-band transponders. The spacecraft will provide communications services to Mexico and its surrounding waters from the 114.9 degree West orbital slot. In addition to the MEXSAT-3 spacecraft, Orbital will also provide the FSS ground segment, including the satellite command and control ground equipment and software as well as training and operational documentation.
