摘要:
使用数值积分的方法对“火卫1”（Phobos）轨道进行预报计算，介绍了计算“火卫1”轨道时考虑的动力模型与数值积分方法，分析了不同动力模型及参量对轨道计算结果的影响，并确定最终选择的模型。最后将计算结果与不同机构发布的最新历表进行比较，计算位置和轨道根数的差异。得到的结果与各星历之间差异的量级相同，进而验证了相关模型和算法的精度和可靠性。该轨道预报算法模型与分析结果将对“火卫1”探测任务提供参考。
Abstract:In this paper,numerical integration is used to calculate and predict the orbit of one of the Martian moons,Phobos. First,the considered force models,parameters and integration methods are introduced. Then the effect of different force models and parameters are analyzed by simulation,and a suggested model is given according to the analysis result. Finally,the difference in position and orbital elements between the proposed model and existing ephemeris is compared. The result shows the same order in magnitude in comparison with the difference of the ephemeris themselves,which proves the precision and reliability of the proposed model. The Phobos dynamical force models analysis and the orbit prediction will help to the exploration missions of Phobos.
