摘要
在总结现阶段共线平动点附近周期和拟周期轨道寻找方法的基础上,在JPL星历提供的真实力模型下利用目标轨道法(Target Shooting Method)实现了Halo轨道的寻找。即利用Lagrange乘数法作为迭代工具,利用圆型限制性三体问题下的分析解结果作为迭代初始值,迭代出真实力模型下的拟Halo轨道。重点构建了真实力模型下的虚拟平动点准惯性坐标系,极大地简化了轨道坐标从CRTBP模型向真实力模型的转换,加快了迭代收敛速度。
The searching methods for periodic and quasi-periodic orbits were summarized firstly. Then the Target Shooting method was realized in the real solar system model to search for Halo orbit, using Lagrange iterative method to refine the initial orbit supplied by CRTBP analytical solution. The attention was paid to the construction of Pseudo-Libration Point Inertial Coordinate, which simplified the orbits' transform from CRTBP to the real solar system model, and speeded up the iterative convergence.
