In order to improve on-orbit imaging performance of optical space cameras, the innovative dual-camera driving mechanism is used to increase the camera in-orbit working mode. The mechanism has the advantages of high synchronization, simple and reliable driving, small resource consumption. First of all, the demand of mechanism movement is analyzed in detail, the scheme of driving mechanism is determined, and then the related parameters of driving mechanism are calculated and analyzed to determine the model of the motor. Then, the cam curve is designed in detail according to the task planning. Finally, Carried out detailed design and kinematic analysis of the institution, and completed the development of the prototype prototype of the reduction ratio. The results show that the organization can meet the requirements of the camera.
