Saft MicroSat Li-ion battery modules to power Turkey’s LEO satellite
Saft has been awarded its first satellite battery contract by Turkey’s TÜBİTAK UZAY (Space Technologies Research Institute). Its space-proven MicroSat standard lithium-ion (Li-ion) battery modules will provide onboard backup power for TÜBİTAK UZAY’s LEO (Low Earth Orbit) reconnaissance and surveillance micro-satellite system. “This is an important contract for a new customer in a new country for us” said Philippe Jehanno, General Manager, Space and Defence Division, Saft.
“Following a number of other recent contracts for programmes such as Canada’s Sapphire and MSI’s OG2 it confirms Saft’s intention to establish a position as the leading Li-ion battery supplier for LEO satellites.” TÜBİTAK UZAY’s LEO micro-satellite is planned to meet the ground imaging requirements of the public organizations. The satellite will be placed in a Sun synchronous orbit at a height of 700 km. The Saft battery modules will work in conjunction with the satellite’s solar array to provide the electrical power for its on-board electronics. When the solar array is fully exposed to the sun it will provide the satellite’s power as well as charging the batteries. When the solar array is ‘eclipsed’ by the earth, with no direct sunlight, the batteries will power the satellite. The satellite will have a period of 98 minutes, so this charge and discharge cycle will be repeated 14 times a day over a five-year design life.
