Summary:An autonomous astronomical navigation method of a spark detector based on an improved MMUPF filtering method relates to an autonomous navigation method of a spark detector. The method comprises the following steps: accurately modeling a deep space detector positioned on a transfer orbit; then measuring with starlight angular distances as quantities; and finally, carrying out optimal estimation ofnavigation parameters by adopting the improved MMUPF filtering method, thereby solving the problem that the planet gravitation size and an orbit dynamics model are changed continuously when the distances are different, and obviously improving the navigation precision. The autonomous astronomical navigation method can be used for determining the navigation parameters of the spark detector or a planet detector positioned on the transfer orbit.
