A thermal/structural/optical integrated analysis method based on the changes of satellite attitude and orbit maneuver parameters is presented, which can reflect satellite camera transient heat flux and the temperature field of the low frequency dynamic process. Depending on the data of real-time temperature field, the real-time on-orbit thermal deformation is analyzed, and the camera optical axis direction of dynamic variation is calculated with thermal deformation data. The modulation transfer function (MTF) of the optical system and the dynamic optical axis direction changes are used to evaluate the image quality and the effect of the thermal control strategy. The analysis shows that attitude changes of high resolution remote sensing satellite cause external heat flux changes in its camera, which causes the temperature field changes of camera optical and mechanical structure. Thus, thermal stability of the camera suffers ordeal. Thermal stress caused by the temperature fluctuation and the temperature gradient makes the optical system to produce rigid body displacement and wave front aberration. As a result, the imaging quality is redused.
