One current research focus is the train positioning technology that takes Beidou satellite navigation and positioning as the core and combines multiple positioning methods.To adress the current problem of obstruction of such structures as rain sheds,which affects satellite positioning accuracy,this paper discusses the feasibility of the technical scheme of"Beidou+5G"fusion for train positioning in the platform area of high speed railways.It also presents the accuracy verification of the 5G positioning technology in an experimental environment(simulated platform environment),and proposes a fusion algorithm for Beidou and 5G positioning data,which provides a new solution for improving train positioning accuracy.
