中间轨道实用化的探讨

本文是在现有中间轨道理论研究的基础上,进一步做实用的探讨。首先建立了中间轨道星历表的标准算法;然后具体导出了中间轨道与瞬时椭园的对应关系;最后给出了建立在中间轨道基础上的有摄星历表的计算方法、与一般有摄星历表计算(采用坐标的数值计算方法)结果的比对表明:中间轨道有摄星历表的算法能够满足解的精度要求,並且略为节省机时。本文所给出的方法为中间轨道的实用化提供了一个初步的可能性,要在实际中应用,还需充分利用中间轨道的优点,进一步改进剩余摄动的计算方法。

RESEARCH ON THE FRACTICABILITY OF THE INTERMEDIATE ORBIT

On the basis of the existing research on the intermediate orbit, a further study of its practicability was made. First, a standard method for the calculation of the intermediate orbit ephemeris was developed. Then, the relation between the intermediate orbit and the instantaneous elliptical orbit was obtained. Lastly, the computation of the perturbed intermediate orbit ephemeris was given, in which the pertubation was calculated numerically. A comparison with the results of the computation of the perturbed elliptical orbit ephemeris indicates that the computation of perurbed intermediate orbit ephemeris saves the calculation a little time. The method provides the possibility of using the intermediate orbit in practice. To do this, the calculation of perturbation needs further improvement
