Saft to Build Li-ion Batteries for MEXSAT-1 & 2

The satellites are part of the new MEXSAT communications system, which will provide government and civilian broadband communications to Mexico – supporting humanitarian needs and enhanced coverage for domestic communications in Mexico.

The new order marks the third contract issued under Saft’s Long Term Agreement signed with Boeing in 2009 for Li-ion GEO satellite batteries. Saft will provide high energy Li-ion batteries consisting of Saft’s qualified VES140S cells. With a 15-year life-span, the battery packs will power the satellites with 14kw of onboard power during eclipse season, which is two 45-day periods per year in GEO orbit.

“We feel honored that Boeing has chosen Saft again to provide strong, long-lasting and reliable satellite batteries,” said Thomas Alcide, general manager of Saft’s Specialty Battery Group. “The MEXSAT satellites will join more than 50 commercial satellites in orbit relying on Saft’s Li-ion technology.”

Saft has a heritage of Li-ion cells and battery packs in space. Other Boeing satellites powered by Saft VES 140 batteries include LightSquared, Intelsat and Inmarsat.

The MEXSAT communications system will consist of two 702 HP Geomobile satellites, MEXSAT-1 and 2, and one Fixed Satellite Service (FSS), MEXSAT-3. Boeing will design and deliver MEXSAT-1 and 2 in an end-to-end L-band mobile satellite services system. Boeing selected Orbital Sciences Corp. to provide the FSS MEXSAT-3 spacecraft.

In addition to civil communications, the MEXSAT system will provide mobile, voice and data services for the Mexican Federal forces. The satellite system will operate over Mexico, the Gulf of Mexico and the Pacific Ocean.
