The inertial system of fighting vehicle existed bracketerror due to its two-axis gyro platform structure, and this could influence the heading precision.
战车用惯性定位定向系统由于采用双轴陀螺平台结构,不可避免地存在着支架误差,从而影响系统航向精度。

Methods of spherical trigonometry and direction cosine matrix were applied respectively to derive the bracketerror, and the two methods had the same error formula and the same calculation results.
