关于初轨计算

初轨计算通常是指在二体问题意义下的短弧定轨，为了适应测量精度的提高和深空探测(包括月球探测)轨道器所涉及力学模型的需要，给出一种在测角资料背景下，同时适用于无摄和受摄运动的初轨计算方法。而且，该方法不仅适用于椭圆轨道，亦适用于双曲线轨道，拓宽初轨计算的传统范畴。

On Initial Orbit Determination

In general,initial orbit determination applies to short arc in the model of two body problem. To meet requirements of increased measurement accuracy and mechanic model associated with deep space exploration (including lunar exploration),here we propose a new method that can be used in both two body problem and perturbed motion. Moreover,it can be used for both elliptical orbit and hyperbolic orbit. Therefore,the traditional area of initial orbit determination is expanded.
