The invention relates to a control circuit, a control method and an optical remote sensing satellite point source calibration system. The control circuit comprises a positioning module used for acquiring and outputting geographical location information of the optical remote sensing satellite point source calibration system; the microcontroller is connected with the positioning module and used for receiving the geographic position information and obtaining a solar pitch angle and a solar azimuth angle according to the geographic position information and satellite time corresponding to the point source calibration system; obtaining a vector angle bisector of a vector angle formed by the first position vector and the second position vector according to the satellite pitch angle and the satellite azimuth angle of the target satellite and the solar pitch angle and the solar azimuth angle, and outputting a control signal based on the vector angle bisector; and the attitude regulation and control module is connected
