摘要
通过分析同步卫星定点保持控制过程中,轨道变化与卫星动量轮转速变化的对应关系,提出了一种利用轨道控制期间卫星角动量变化实现控制效果的快速评估算法。该算法可在点火结束后较短时间准确评估出轨道半长轴、漂移率和偏心率的变化量,具有评估时间短,精度高的特点,在实际卫星控制中得到了很好的应用。
The relationships between orbit variations and MW rotation rates variations during station-keeping control are analyzed and bring up a new evaluation algorithm for resules of station-keeping control by using variation of angular momentum.This algorithm can rapidly evaluate the control results and precisely obtain variations of semi-major axis,eccentricity and longitude drift rate after the orbit control.The algorithm has characteristics of rapid evaluation and high precision,and it is successfully applied to GEO satellites operation.
