多源融合导航技术综述

摘要

With the rapid development of positioning and navigation technologies, Location Based Services (LBS) have provided better and better experiences for users. However, single positioning source cannot always meet the precision requirement, meanwhile, the robustness and reliability are not considerable enough. Based on the information fusion technology, homogeneous and heterogeneous information from different navigation sources is fused in the multi-source data fusion navigation to achieve the best fusion result. Compared with traditional single source based navigation, multi-source information fusion navigation takes full advantage of all fusion sources. Data fusion and multi-source data fusion navigation are analyzed and summarized in this paper as well as multi-source fusion algorithm and its performance evaluation.%随着定位与导航技术的快速发展，基于位置的服务给人们带来越来越好的用户体验。但是单一的导航源往往达不到用户的精度要求，同时也不具备足够好的鲁棒性和可靠性。多源融合导航基于信息融合技术，将来自不同导航源的同构或者异构的导航信息按照相应的融合算法进行融合，从而得到最佳的融合结果。相对于传统的单一导航源，多源融合导航可以充分利用每一个导航源的优势，从而提供最好的定位与导航服务。对多源信息融合以及多源融合导航技术进行分析和概述，同时阐述常用的多源融合算法及多源融合导航的性能评估。
