摘要
针对INS导航定位的精度低、GPS导航定位的非自主性,采用INS/GPS组合导航的方式,重点阐述了系统模型的建立,在Matlab/Simulink平台下对系统进行仿真实验时,采用了基于无重置的联邦卡尔曼滤波器的组合方案,实验表明了组合系统比任何单一的导航系统的定位精度都要高,是一种可行的导航方法.
To aim at low precision in navigation and position of Inertial Navigation System and dependence of Global Positioning System, this article adopts the mode of INS/GPS integrated navigation and is centrally devoted to the system modeling .In this article, the Matlab/Simulink tools are used to simulate systems, in which the combined scheme based on No-Reset Federal Kalman Filter is adopted. It is concluded by experiment that the precision in position of integrated systems which are feasible methods for navigation is higher than any other navigation systems.
