| 摘 要： | 通过误差分析对三种捷联惯导系统解析粗对准方法进行了比较.指出在相同的传感器精度条件下,利用正交向量计算捷联矩阵比传统方法有更高的对准精度,直接计算法不仅精度高,而且计算简单,更适合工程应用.

| Abstract: | Three analytic coarse alignment methods to strapdown inertial navigation system are compared via error analysis. The later two are superior to the traditional one because their east level drift misalignment angles are not corrupted by gyro uncertainty. Due to its high accuracy and computation efficiency, the direct method is more suitable for practical applications. |
