Zusammenfassung:	The present invention relates to an antenna beam attitude control method and system. The control method comprises: controlling an antenna to perform scanning of a satellite within a preset range and acquire an antenna beam vector; collecting antenna attitude parameters of the antenna during the scanning process; implementing attitude fusion filtering processing of the antenna beam vector and the antenna attitude parameters to acquire an attitude angle of the antenna; implementing coordinate conversion of the attitude angle to acquire target operating information of the antenna; on the basis of the target operating information, controlling a servo drive system to track the satellite and, on the basis of the antenna beam vector of the antenna tracking the satellite, acquiring the attitude angle to form a closed loop. The present method introduces antenna beam vectors to form full closed loop attitude control, and can thus dynamically correct errors causing beam attitude control. In addition, limitations on the
