为了解环火星探测器的运动规律,就要构造环火星探测器的轨道分析解,这会涉及2个火星自然卫星的分析历表,因而需要首先构造它们的轨道分析解。由于火星与地球类似,参照建立人造地球卫星轨道摄动解的方法,构造火星自然卫星轨道的摄动分析解,分离出短周期项,即可给出所需要的历表计算公式。将其与JPL网站上提供的历表进行比对,结果表明,所采用的数学模型以及构造轨道摄动解的方法均有效,能够达到期望的精度。
In order to understand the movement law of the ring Mars rover, it is necessary to construct the orbit analysis solution of the ring Mars rover, which involves the analysis of two Mars roaches, so we need to construct their orbit analysis solution first. Because Mars is similar to Earth, referring to the method of establishing orbital perturbation of artificial Earth orbit, we construct perturbation analytic solution of Mars orbit of natural orbit, and separate the short-term term to get the required formula of lunar calendar. Comparing it with the calendar provided on the JPL website, the results show that both the mathematical model used and the method of constructing orbital perturbations are effective and can achieve the desired accuracy.
