The invention relates to a mobile satellite alignment method for fast recovery type mobile communication, Through the introduction of high-precision GPS information, the method uses information of a GPS speed position and the like as reference quantity of an inertial navigation system and carries out information fusion and resolution with the inertial navigation system; on the basis of the prior static alignment dynamic tracking, the method is added with dynamic pedestal alignment technology, namely under the moving state of a carrying vehicle, the method resolves out the azimuth angle of the carrying vehicle relative to the positive northern direction and the attitude angle relative to the horizontal surface through the comprehensive calculation of a peg-top, an accelerometer and other sensors; and the method adopts closed loop extremum scanning technology and realizes the capturing and locking of a satellite under a dynamic environment to keep an antenna stable in the dynamic environment. The method adopts rapid dynamic pedestal alignment technology through laser inertial navigation and can automatically complete the dynamic pedestal alignment function of the inertial navigation system; and the method adopts the closed loop extremum scanning technology and realizes the capturing and locking of the satellite under the dynamic environment to keep the antenna stable under the dynamic environment. Moreover, the mobile satellite alignment method greatly improves the rapid responding capacity of the mobile communication system.
