About
The Reflector form Readjustment Device is an electromechanical system based on linear drives, specifically designed for the precise adjustment of the reflective surface profile of large reflectors. Its primary purpose is to modify the reflector’s operating surface profile in response to commands received from a control system. This capability is crucial for maintaining optimal performance of large space-based reflectors, such as those used in communication satellites or scientific instruments, by compensating for thermal distortions or reconfiguring the antenna beam. The device offers configurations with either 8 or 12 thrusts, each capable of exerting a force of 260 N. It provides a working path of ±20 mm with a thrust transfer error not exceeding 0.125 mm and a thrust transfer rate of 0.7 to 1 mm/min. The operational life is defined by 575 switching cycles, with an active lifetime of 10 years and an overall guaranteed lifetime of 14 years, indicating its suitability for long-duration space missions.
