Abstract :
Taken guided rocket bomb as the research object and aimed at trajectory correction, the kinematics model of guided rocket bomb is established and a strap down inertial navigation system(SINS) is designed using MEMS inertial sensors. According to the output data of guidance system, a differential geometry algorithm is proposed to calculate the curvature of the actual trajectory. Compared it with the which of the designed trajectory, deviate error is obtained to control rudder leaning angle to achieve trajectory correction. The simulation analysis shows that the method can greatly improve the accuracy of long-range rocket bomb.
