摘　　要：惯性定位系统是利用安装在载体上的惯性敏感器件获取加速度和角速度等信息,只要与载体的初始位置信息相结合就可自主递推出载体的运动方向、位置以及运动速度。惯性导航具有自主性强、隐蔽性好、可实时定位以及全天候工作等优点。目前人们在不断探索提高惯性定位系统精度的同时,还在寻求形成组合式导航系统。本文概述了各种技术的性能及其应用,阐述了几种主要的定位技术,就性能和精度比进行对比,最后对各种定位技术同惯性定位系统组合进行了研究。Inertial positioning system obtains the acceleration and angular velocity information using the inertial sensitive device mounted on the carrier. If combined with the initial position information carrier, it can independently deduce the direction of movement, the position and velocity vector. Inertial navigation has many advantages, such as strong independence, good concealment, real-time positioning and all-weather operation. At present, people constantly seek to improve the accuracy of inertial positioning system, and to form a combination of navigation systems. In this paper, the performance and application of various technologies are summarized. Several main localization technologies are described, the performance and precision ratio are compared. and inertial positioning system are studied. Finally, the combination of various positioning technology
