| 摘 要： | 文中对开普勒轨道方程中的经典f、g 级数进行修正,使其适用于考虑主要带谐项的摄动情形,克服了f、g 级数仅用于开普勒轨道短弧段的限制。公式的推导借助计算机完成。使用此方法所得结果与使用数值积分方法所得结果比较:该方法速度快、精度高、可直接得到连续的状态。该方法简洁有效,在航天导航和制导领域具有很大实用价值。

| Abstract: | This paper presents a correcting method for classical f and g series which is to be used in cas-es considering the primary perturbations of the zonal harmonies.It overcomes the limitation of fand g series only suitable to short arc.The results derived with CA system REDUCE are also giv-en.Comparing the results using this corrected f and g series with those from direct numerical inte-gration method,we can see that the former is faster and with the same accuracy.Besides,it canprovide continuous states instead of discrete ones.Its clarity and effectiveness make it vary usefulin space engineering. |
