摘要
分析表明,卫星轨道偏差对预报的影响主要表现在M和Ω这两个轨道根数上。本文给出了M、Ω的修正公式,并结合LAGEOS测距数据,对卫星的短期预报进行修正,取得了满意的结果。
It is shown that the bias of M (mean anomaly) and Ω (longitude of ascending node) affects mainly the deviation of LAGEOS orbit. So, the correction of M, Ω, by processing range data could significantly improve the prediction of LAGEOS in short period.
This paper gives out the relevant correction formulae, block diagram of computing program and the results obtained as an example of their application, which seems satisfied.
