The invention provides a semi-physical simulation testing system for a deep space autonomous navigation star sensor and a method thereof. A star sensor simulator is placed on a similar support frame, and an autonomous navigation star sensor is fixed on a three-axis rate rotating table; the center of an entrance pupil of the autonomous navigation star sensor is arranged on a horizontal rotation central axis of the three-axis rate rotating table; an emergent pupil of the star sensor simulator is in butt joint with the entrance pupil of the autonomous navigation star sensor, and an optical axis of the star sensor simulator is superposed with the optical axis of the autonomous navigation star sensor; and the autonomous navigation star sensor, the three-axis rate rotating table and the star sensor simulator are all connected with a control and information processing computer. By adopting the system and the method, star simulation for the very high-precision star sensor for autonomous navigation of a minor planet can be solved, and the measurement precision of the star sensor and the autonomous navigation positioning precision are verified, thereby having broad application prospects fordeveloping the deep space autonomous navigation sensors.
