| 摘 要： | 该文以旋转矢量误差最小为标准，用估计的方法推导出了一种高精度的捷联姿态解算方法，该算法在较小的陀螺采样频率下，以适中的计算量就能达到较高的姿态精度，对二子样算法、三子样算法和本文提出的算法在典型圆锥环境进行了数字仿真，结果表明，本算法大大减小了圆锥误差，提高了姿态精度。

| Abstract: | This paper deduces and derives a high-accuracy strapdown attitude algorithms ,which minimizes the rotation vector error.The algorithm can reach high attitude accuracy with little gyroscope samples interval and small workload of computing.Simulation has been made and it is compared with two-sample,three-sample algorithms in classic coning environment.The results indicates that the dynamic error is significantly reduced,and the attitude accuracy is improved with the algorithm. |
