摘　　要：针对目前提高捷联惯导系统自对准精度难度大这一情况,在建立SINS静基座初始对准的误差方程的基础上,通过对影响对准精度的误差因素进行分析,提出了一种在载体内部安装高精度自主寻北装置的方法,该方法可有效地提高初始对准精度。Based on the fact that it is very difficult to improve the autonomous alignment accuracy of strapdown inertial navigation system （SINS）, an error function for static-state initial alignment of SINS is built. Then an analysis is made for the factors which have effect on the alignment accuracy, and a method is put forward for installing a high-accuracy, auto-north-seeker in the carrier, which can improve the alignment accuracy effectively.
