摘要: |
本文给出了全星历模型下适用于地月系统和日地系统的拟Halo轨道的设计方法。设计过程以限制三体模型下Halo轨道作为初值并以多点并行打靶法求解全星历模型下拟Halo轨道。采用多点并行打靶法中给出了一类新的可行约束条件,在数值仿真算例中,地月和日地系统L2点附近4圈目标拟Halo轨道均在分钟量级时间内收敛,表明了算法的有效性。 |

Abstract: |
A method of designing the quasi Halo orbits in the full ephemeris model, which can be applied in both the earth-moon system and sun-earth system, is presented. In the design process, a Halo orbit designed in the restricted three-body model is taken as initial guess, and then a multiple shooting method is used to design in the full ephemeris model. A new feasible constraint condition is given. By numerical simulations, the quasi Halo orbits with four circles are both obtained about one minute for the earth-moon system and sun-earth system respectively, showing the effectiveness of the present algorithm. |
