星敏感器误差分析与补偿方法

摘要

星敏感器是目前航天器精度最高的姿态测量部件,其误差是影响姿态确定系统精度的关键要素.依据误差频率特性,系统地对星敏感器误差进行分析,主要阐述星敏感器低频误差和高频误差产生的原因以及当前的抑制与补偿方法.在此基础上,根据星敏感器误差的特点,展望星敏感器低频误差以及高频误差抑制与补偿方法的发展趋势.%Star sensors are the most accurate attitude determination instruments in a satellite.The error of star sensor is the key point of the precision of attitude determination system.In this paper,the error sources of star sensor are summarized systematically according to the frequency characteristics.The error analysis,suppression and compensation methods are reviewed so as to provide references for further study.Based on these introductions,the development trend of error suppression and compensation for star sensor's low frequency error and high frequency error is investigated.
