摘要
对景象匹配定位导航的工作原理进行了数学化描述,讨论SINS/SMNS组合导航系统的信息融合算法,重点研究了其中两种信息融合算法:外推法和Lyapunov自适应滤波算法.通过仿真实验表明,景象匹配可有效地减小组合导航系统的位置误差.
The operating principal of scene matching locating navigation is discribed mathematically,and the information fusion algorithms used in SINS/SMNS combined navigation system is discussed,in which extrapolation and Lyapunov adaptive filtering mehtods are mainly researched.The simulation results indicate the scene matching can reduce the position error of combined navigation system effectively.
