More Information
Summary:The invention relates to an autonomous celestial navigation method for a deep space explorer on a swing-by trajectory. The autonomous celestial navigation method comprises the following steps: establishing the corresponding equation of state according to the distance to a planet; calculating the location information of the planet by using the sensitive starlight angle distance detected by a star sensor and calculated by pure astronomic and geometry analytic method; and estimating the parameters of the navigation system by using a fuzzy multiple-model adaptive unscented Kalman filtering (FMMUKF) method. The invention is suitable for the navigation location of a deep space probe on a swing-by trajectory and applicable to the determination of navigation parameters of the deep space probe on a multi-celestial-body intersection swing-by trajectory, belonging to the technical field of aerospace navigation.
