摘要
航天器高动态星光定位实验室仿真的前提是确定视场内的恒星,以便进行后续的星图模拟、星图处理和定位解算。通过对低空和高空载体恒星观测的分析和推导,运用球面天文学基本关系,提出了基于多种约束条件下的星光定位恒星优选算法,能够实现载体任意空间位置星敏感器视场内观测恒星的确定,最后通过选星程序设计和选星仿真验证了该方法的有效性。
In order to establish the laboratory simulation system of CNS, the stars in the scope of space-craft must be confirmed first, then the following work such as star chart simulation, star chart processing and so on could be done accordingly. Based on the analysis and reasoning of the star observation from carrier in low altitude and high altitude,a optimal star selection arithmetic of the celestial positioning is brought forward based on the spherical astronomy. The validity of the method in this paper is proved by the program of star selection as well as the lab simulations.
