Voice coil actuators for two MTG instruments
19 June 2023
While Cedrat Technologies has been active in space for more than 20 years with piezoelectric mechanisms, we have also been increasingly involved over the last few years in the development of magnetic actuators for space projects. In this paper, a focus is made on the case of magnetic actuators that are developed in the frame of the Meteosat Third Generation (MTG) project. The first one is the Scan Assembly (SCA) actuated by Rotating Voice Coil Motors (RVCM) for the East/West (E/W) axes and the North/South (N/S) axes developed in collaboration with Sener and the second one is the Voice Coil Motor (VCM) developed in collaboration with CSEM for the Corner Cube Mechanism (CCM)
