摘　　要：基于导航定位技术的背景,提出从信息处理角度分析惯性导航系统工作原理的方法。首先介绍了惯性导航和卫星导航各自的应用特点及差异,然后对运动参数坐标系的选取、地球特征的描述、陀螺角速度的测量值和加速度计的比力测量值的具体含义、地理垂线和真北作为基准线的作用等与信息处理过程密切相关的关键技术点进行了提炼与解析,最后对载体不同位置处精确导航信息的获取技术、导航信息融合技术和惯性导航系统的研制现状与发展趋势进行了探讨与展望。所提方法为进一步研究惯性导航系统中信息处理特点提供了参考。Based on the background of navigation and positioning technology, put forward the method to analyzing the working principle of inertial navigation system from the aspect of information processing. Firstly, introducing the application characteristics and differences of inertial navigation and satellite navigation. Secondly, refining and analysis the selection of motion parameter coordinate system, description of earth’s characteristics, the specific meaning of the measurement value of gyro angular velocity and the specific force measurement value of accelerometer, the function of geographic vertical line and true north as datum line is closely related to the process of information processing. Finally discussing and prospecting the development status and tendency of precise navigation information acquisition technology, navigation information fusion technology and inertial navigation system in different positions of the carrier. This method provided the reference for further study of information processing characteristics in inertial navigation system.
