捷联惯导两种姿态算法抗干扰性能比较

Anti-jamming property comparison between the two SINS attitude algorithms

在有噪声干扰的情况下,比较了四阶龙格库塔算法和三子样算法对捷联惯性导航精度的影响。在典型的圆锥运动下,将陀螺仪的输出加上不同强度的高斯白噪声,用这两种算法进行姿态解算仿真,仿真结果表明,四阶龙格库塔算法的抗干扰性较好。

We compare the fourth-order Runge-Kutta algorithm with the three-sample algorithm for improving the SINS accuracy under noise disturbances. With classical coning motion, the gyro output carrying Gaussian white noise is analyzed by means of simulation and the results show that anti-jamming effects of the fourth-order Runge-Kutta algorithm is more effective .
