| 摘 要： | 在捷联惯导中等效转动矢量的精度直接影响着姿态矩阵的精度，分析了等效转动矢量的迭代算法，推导出了Ｎ子样迭代算法，并进一步导出等效转动矢量的计算误差取决于采样频率。以典型圆锥运动为例，分析了采样频率与等效转动矢量的计算误差及圆锥运动的角速度的关系，并以仿真加以说明。

| Abstract: | The error of updating rotation vector is the main one of attitude
computation in strapdown inertial navigation system(SINS).The general algorithm of updating
rotation vector is introduced and analyzed in this paper,where N samples recursive algorithm
is derived.The conclusion that the computation accuracy is determined by sample frequency is
given.The paper also analyse the relation among computation error,angular velocity and
sample frequency.And the simulation results demonstrate the conclusions. |
