| 摘 要： | 对于改进的Ｅｎｃｋｅ方法，选择适当的参考轨道是一个关键．然而，对于人造地球卫星长弧轨道计算，目前所给出的几种参考轨道均需要逐段校正，这将给定轨问题带来附加的复杂性．本文将仔细探讨如何选择参考轨道和减少校正次数．

| Abstract: | It is the key to select a suitable reference orbit for modified Encke method. But the reference orbits for the long-arc orbit calculation of an artificial satellite must be rectified section by section. The rectifications will at the same time,intreduce additional complexities into the calculation of orbit determination.In this paper we investigate carefully how to select a suitable reference orbit and how to reduce the number of rectification. |
