Abstract
Multi-beam antennas generally adopt narrow beam coverage, frequency multiplexing and other technologies, which have high requirements for antenna pointing accuracy. For communication satellites in synchronous orbit, a scheme of in orbit pointing calibration of multi-beam antenna is proposed based on the principle of amplitude comparison monopulse. By comparing the amplitudes of the beacon signals, the antenna pointing measurement is realized, the compensation parameters are generated, and the antenna pointing control is realized by adjusting satellite attitude. Based on the analysis of pointing error source and calibration error, the accuracy of calibration is estimated, and the calibration performance is simulated.
