| 摘 要： | 通过对惯性制导系统两个基本方程的研究,求出了各状态矢量在各坐标系下的微分方程,然后以ψ角法所确立的平台为基准,分别推导得出惯性制导系统各主要状态的微分方程,从而建立了捷联惯性制导系统的误差模型.最后根据静基座捷联惯导系统初始对准的特点对其进行简化,得到了静基座捷联惯导系统快速自对准的误差模型.

| Abstract: | Based on the research of two fundamental equations of inertial guidance system,differential equations of each state vector were deduced.Then according to the platform established by angle method,defferential equations of main states of the inertial guidance system were given,so the error model of strapdown inertial guidance system was established.In the end,for the sake of static-based initial alignment,the equations were simplified and finally the error model of static-based fast self alignment for strapdo... |
