数据融合技术在船舶组合导航中的应用研究

摘要

As the combined application type of boat＇s navigation system,it is necessary to fuse integrated navigation information in order to supply reliability navigation information.This paper discussed the main data fusion methods that used in the boat＇s navigation system,of which on the basis the sensor local information fusion algorithm was pointed out aiming at the structure of federated filter,and the fault-tolerance of federated filter that adopted local sensor navigation information fusion algorithm was also analyzed in the end.All this work is significative for promoting the application of data fusion technology in boat＇s integrated navigation system.%随着船舶导航系统的组合应用,有必要对组合导航信息进行数据融合以提供高可靠性的导航信息。在简单分析了船舶导航信息主要的数据融合方法的基础上,针对联邦滤波器的结构设计了传感器本地多次数据融合决策算法,并对融合了传感器本地决策数据融合算法的容错性进行了分析,对于推动数据融合在船舶组合导航中的应用具有一定借鉴意义。
