| Abstract: | According to the features of cross orbit vehicle and the demands of light miniaturization,a navigation approach of conical scan is proposed,which uses refraction measurements of starlight passing through the upper atmosphere.Then,the model of the system is built and linearized.The algorism is based on EKF,and is proved by simulation at last.The approach provides a new idea to the design of small light autonomous navigation system. |
