Magnetic Fast Steering Mirror for Inter-satellites and Feeder Link Optical Communication

In order to cope with performances of Fine Pointing, and Fast Steering mirror requirements for Space Optical Communication, CEDRAT TECHNOLOGIES (CTEC) is developing magnetic Fast Steering Mirror’s (M-FSM) family, based on proprietary MICA(TM) flexure bearing magnetic actuators mechanism (Moving Iron Controllable Actuator), with embedded eddy current sensors (ECS). FSM design expected for Optical Inter-Satellite Link (OISL) in large-scale New Space constellations, is highly driven by mandatory cost-efficiency for high quantities recurrent production, while FSM design expected for Feeder-Link communication is driven instead by high power Laser requirements together with high level of redundancy. In this publication CTEC is presenting both the M-FSM45 and M-FSM-HPL designs, and test results, respectively for inter-satellites and feeder link optical communications.
