摘要
针对组合导航系统在数据处理时存在的计算量大和故障数据相互污染的问题 ,提出了一种基于信息融合的导航参数最优估计滤波方法。文中首先介绍了信息融合的基本原理、关键技术以及常用方法 ,然后以INS/GPS组合为例 ,对组合导航系统的工作原理和模型建立进行了详细的分析 ,最后通过计算机仿真证明了该方法可提高导航系统的计算精度和速度 ,有较好的容错性和环境适应性 。
A new method of optimum navigation parameter estimate based on information fusion is presented in this paper in view of the heavy calculation and faulted data spread in integrated navigation system. Firstly, the author introduce the basic principle, key technology and methods of information fusion, then explain the principle and mathematics model of the INS/GPS integrated navigation system in detail, at last give the computer simulation. The results show that this method is practical for improving accuracy and calculation speed of navigation system.
