The invention discloses a satellite-ground integrated high-precision satellite multi-beam calibration method. On-satellite calibration beam forming equipment is used for achieving multi-beam calibration signal generation and beam forming. A ground calibration station is located at the theoretical pointing center of a multi-beam calibration beam, and real-time beam pointing error information is obtained by capturing and receiving calibration signals and measuring power. Measured data are transmitted to the control center through a ground link or a satellite link; wave beam pointing deviation compensation parameters are generated in the control center and sent to the satellite measurement and control station; and the satellite measurement and control station converts the beam pointing deviation compensation parameter into an upload instruction and injects the upload instruction into the satellite platform. According to the method, a ground calibration mode is adopted, the requirement foron-satellite operational capability can be reduced, an on-orbit operation processing flow is simplified, measurement errors caused by satellite power fluctuation are reduced, the precision of a calculation result is improved, and the method has the advantages that the system structure is clear, the calibration process is clear in division of work and positioning, and the operation complexity of adeviation calculation method is low.
