| Abstract: | The observability of the navigation approach using starlight refraction measurements is analyzed based on the theory of local weak observability.The influence of different observing manners to the system observability are analyzed according to the condition number of the observable matrix,thereby,the best observing manner is found,which provides the reference direction to the real measurements. |
