摘　　要：针对捷联惯导系统中初始对准的问题,本文采用了设计卡尔曼滤波器的方法,通过建立惯导系统的误差模型,分析卡尔曼滤波的基本理论,以东向和北向速度误差进行分析。通过初始对准计算机仿真结果,进一步验证了该方法的快速性与准确性,所得结果可以为进行惯导系统快速精确对准方法研究提供理论与工程应用思考,这说明卡尔曼滤波在惯导系统中应用是有效的。In order to solve the problem of initial alignment in strapdown inertial navigation system,the Kalman filter is designed and the error model of inertial navigation system is established. The basic theory of Kalman filter is analyzed and the velocity error is analyzed in east and north direction. The results of emulation show that the method has the advantage of rapidity and high degree of accuracy. The work in this paper can provide the academic and engineer reference for studying the fast and accuracy alignment method of SINS on revolving bases. The result illustrates the efficiency of the method.
