Abstract: The influence of micro-vibration on the image quality is a key factor in the development of high resolution remote sensing satellites. In order to simulate this influence, the source of the micro-vibration is analyzed firstly. Then a model of the micro-vibration transmission is established, including the structural transmission and the attitude control loop. Next, a mathematical model is set up for describing the relation between the motion of the optical element and the LOS jitter. Lastly, the influence of the micro-vibration on the LOS of the camera is simulated and analyzed. The imaging of a subject sample is used to demonstrate this influence. It is concluded that the influence of the CMG cannot be neglected, and that the micro-vibration of the CMG must be controlled to ensure the image quality.
