Synchronous satellite multi-beam antenna pointing calibration method and device and electronic equipment

The invention provides a synchronous satellite multi-beam antenna pointing calibration method and device and electronic equipment, and relates to the technical field of satellite measurement and control. Specifically, antenna beam pointing deviation data, calibration station position data and satellite fixed point centroid position data at a target sampling moment are adopted to calculate satellite attitude compensation data at the target sampling moment, and the satellite attitude compensation data at a plurality of sampling moments within a specified time period are fitted by using a Fourier series method, so that the satellite attitude compensation accuracy is improved. Compared with a traditional empirical estimation method, the method provided by the invention can effectively improve the precision of satellite attitude data evaluation, so that the method provided by the invention can compensate for an antenna pointing constant error and a periodic error, shorten a calibration period, improve the antenna
