对空间多目标多次接近的轨道设计

Orbit Design for Approaching Multiple Spacecrafts Repeatedly

基于单航天器对空间多目标单次接近轨道设计的研究结果,讨论了单航天器对空间多目标多次接近的轨道设计问题.提出了接近指标用于设计能多次接近多个空间目标的航天器轨道;以二体接近轨道为基础,给出了接近轨道解空间的求取方法;利用三种轨道调整方法构造了三种复杂度不同的新解并产生算子,分析了它们的解空间和最优解分布,采用改进的模拟退火算法求解出最优接近轨道.仿真实验验证了轨道设计算法的正确性.

The orbit design for single spacecraft approaching multiple spacecrafts more than one time is discussed in the paper,based on the result of orbit design for single approaching multiple spacecrafts once.The technique of determining approaching domain,which is established from the two-body approaching orbit,and the approach extent evaluation,which can be used to orbit design of approaching multiple spacecrafts repeatedly,are presented in the paper.Based on three types of orbit adjustment,three operators with different computation complexity are constructed to generate the new approaching orbits,and the scale of their corresponding approaching domain and the distribution of the optimal approaching orbit are analyzed.The improved simulated annealing algorithm is employed in the paper to solve the optimal approaching orbit.At last,the simulation experiment demonstrates the validity of the orbit design algorithm.
