| 摘 要： | 研究了磁航向和捷形惯性组合系统初始对准的设计方法。该方法能在初始对准过程中用卡尔曼滤波器估计出陀螺仪的随机常值漂移，从而提高了系统的对准精度。文中给出了系统的状态方程和测量方程，建立了完全闭环控制的卡尔曼滤波器，最后给出了二组不同条件下的模拟结果。

| Abstract: | Disscuss the alignment method of a magnetic heading and strapdown inertial integrated system. This method can estimate the random constant drifts of gyros,so that a high alignment accuracy of the integrated system is achieved. Give the error model of the integrated system. The algorithm of the closed-loop control Kalman filtering is established. Several simulation results under different conditions are shown. |
