The invention discloses a low-orbit detector orbit precision improving method, and belongs to the field of deep space navigation detection. The method comprises the following steps: calculating acceleration generated by each sailboard of a detector, and accumulating to obtain acceleration generated by light pressure of the detector; calculating the acceleration of each sailboard of the detector caused by the planetary radiation pressure and the acceleration accumulation of the reflection force and the infrared radiation force borne by the detector to obtain the total acceleration of the detector; performing numerical integration according to the total acceleration of the detector to obtain a calculated value; calculating a centroid correction value from the phase center of the antenna to the centroid of the detector, and adding the centroid correction value and the calculated value to obtain a corrected calculated value; and adopting the corrected calculation value to continuously carry out iterative calculation to obtain a high-precision precise orbit. According to the method, the high-precision multi-sailboard model is used for modeling each part of the detector and performing high-gain antenna correction, so that not only can the precise light pressure of the detector be obtained, but also centroid correction can be performed, and thus the overall orbit precision of the detector is improved.
