遥感系列卫星在轨微振动测量与分析

摘要

在遥感系列卫星上装载了微振动环境测量系统并进行了在轨微振动环境测量。文章介绍了4颗遥感卫星的在轨微振动环境参数获取与分析。结果表明：星上各活动部件中主要的扰振源为反作用轮和辐射计/散射计转动机构；卫星稳定运行时的最大微振动量级约为57 mg，传递到光学敏感设备衰减度约为15%。%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.
