Based on the study of impulse correction force, this paper establishes both the motion equation of center of mass and the rotation equation of the guided rockets using impulse correction, and demonstrates the feasibility of the model through computer simulation. (1) The correction distance increases as the force increases, and the correction distance is the maximum when the force is 5 000 N. (2) The correction distance increases as the distance between the force point and the center of mass increases, and the correction distance is the maximum when the distance between them is 0.5m.
