Abstract: A micro-vibration environment measurement system is built on a series of remote sensing satellites to measure the micro-vibration environment in-orbit. Some micro-vibration environment parameters of the remote sensing satellites in-orbit are obtained and analyzed. The measurement results indicate that the reaction wheels and the rotary mechanism of radiometer/scatterometer are the main sources of the micro-vibration, and the largest micro-vibration acceleration is about 57 mg with the attenuation of approximately 15% when it is transferred to the optical sensitive device location.
