Boeing Space & Intelligence Systems awarded a contract to Saft to supply lithium-ion (Li-ion) satellite batteries for MEXSAT-1 and MEXSAT-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. 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 batteries consisting of its qualified VES140S cells. With a 15-year life span, the battery packs will power the satellites with 14 kW of onboard power during eclipse seasons (two 45-day periods per year in GEO orbit). 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.
