P-FSM150S Fast Steering Mirror for Optical Space Constellations

New space giant constellations based on Free-Space Optical Communication (FSO) are a new challenge from many perspectives. Considering the mandatory cost efficiency, with repeatability of performances, and reliability with no defect at customer integration, requires an upheaval in space production and acceptance test methods, when the quantities are beyond several thousands of units. Starting from the former PYSCHE PAM30 flight project heritage for Deep Space Optical Communication (DSOC), CEDRAT TECHNOLOGIES (CTEC) presents the new design and test results of the P-FSM150S Fast Steering Mirror (FSM) Engineering Models, developed under ARTES project TELCO-B for future FSO constellations. The specific cost-efficient hardware design is presented, dedicated to very large quantities to be manufactured, together with the performance test results over a preliminary batch of EM’s production. The environmental tests campaign for Space qualification was passed, and is presented, which includes launch vibrations and shock tests, thermal vacuum tests, and high frequency accelerated lifetime fatigue tests.
