针对星光大气折射观测导航方法的可观性展开研究,利用局部弱可观理论分析了方法的可观性,根据构造的可观性矩阵的条件数考察了不同观测方式对导航系统的可观性影响,据此找到了最佳的折射观测方向,为实际选择折射星提供了参考方向。
Aiming at the observability of the navigation method of star atmosphere refraction observation, the observability of the navigation system is investigated by observing the observability of the navigation system by using the local weak observability theory. The observability of the navigation system based on the constructive observability matrix is investigated. The best direction of refraction observation provides the reference direction for the actual selection of refraction stars.
