The invention provides a sun-synchronous orbit moonlet electric propulsion orbit control autonomous planning method. According to the method, a mode of constructing a sub-satellite point trajectory of a satellite is adopted, a screening method of an autonomous orbit control starting moment is given in consideration of satellite charging requirements and avoiding of business conflicts, and an autonomous orbit control task planning method is designed in consideration of an electric propulsion orbit control capability and an on-board computer capability; autonomous orbit control may execute an expected number of orbit control services according to a plan. The solar synchronous orbit small satellite electric propulsion autonomous planning method has the advantages of being few in uploading instruction, simple in algorithm, small in calculation amount, accurate in result, high in anti-interference capacity and the like, meets the performance limitation of a spaceborne computer, and can autonomously run on a satellite.
