| 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。

| Abstract: | 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. |
