Embodiment Construction
[0037] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0038] The invention discloses a satellite-ground integrated high-precision satellite multi-beam calibration method, which is realized by using on-satellite calibration beamforming equipment, ground calibration stations, control centers and satellite measurement and control stations, wherein the on-satellite calibration beamforming The equipment is used to generate multi-beam calibration signals containing satellite attitude on the orbit and send them to the ground calibration station. The position error between the power overlapping point of the multi-beam calibration signal and the ground calibration station is used to calculate the deviation of satellite attitude. So as to achieve the purpose of satellite-ground integrated calibration; the ground calibration station is used to receive the calibration signal generated on the satellite, and measure the beam pointing ...
