Recently,people are proposing to build a deep space navigation constellation in the Earth-Moon system which utilizes libration points of the Earth-Moon system.In the true model of the solar perturbation,the libration points of the Earth-Moon system are unstable,which leads to the navigation constellation must be controlled in a certain area.This paper introduces a special kind of libration point orbits,called as Dynamical Substitutes (DSs),using inter-satellite range data,the autonomous orbit determination problem of DSs is studied in this paper,due to their long-term stability.As a result,during the whole process of autonomous orbit determination,no support from the ground stations is needed,and studies show that the orbit determination accuracy can reach that of the observation.So,in order to obtain good Autonomous Orbit Determination (AOD) results,the data length should not be too short,and the satellite should have motion component perpendicular to the Moon's orbital plane.The current study can be used when deploying the navigation constellation in the Earth-Moon system.
