Abstract: With increasing demand for high resolution，integration and agility of optical remote sensing small satellites，visible/infrared dual-color common aperture camera as well as CMG（control moment gyroscope） are installed to meet the requirements of miniaturization，all-day and night，multi-target and multi-model imaging.On such satellites there are several kinds of components with micro-vibration，including CMG，infrared camera cryocooler，etc.，which has a great influence on image quality of camera and is difficult to suppress.Therefore，a comprehensive method for suppressing microvibration caused by above-mentioned disturbance sources is proposed，including CMG vibration isolator，isolating installation between cryocooler and camera optical structure，and damping truss is designed and installed to realize isolation between camera optical and satellite platform structure.Using above integrated disturbance source damping and terminal isolation measures，through analysis，calculation，satellite micro-vibration experiment verification and in-orbit test，the effect of micro vibration on image quality can be effectively reduced.Even for visible infrared integrated camera，the in-orbit dynamic MTF（modulation transfer function）of visible channel with sub-meter resolution can reach 0.1，and the influence factor of micro vibration on MTF can be controlled at 0.991.
