| Abstract: | The deficiencies of the algorithm method for attitude angle in flight vehicle are analyzed in this paper. In this algorithm method, the attitude angle of flight vehicle is calculated by integral value of rotation & motion differential equation, through the calculating of direction cosine and quaternion. Then the improved Newton method for attitude angle in flight vehicle is introduced as well. According to the mean value effect of multi-measurements, the algorithm method for improving attitude angle calculating-precision in flight vehicle by using maximumly the above two methods is deduced.Simulation result shows the good effect of this method |
