摘　　要：信息时代的到来,使导航技术的应用范围显著扩大,特别是北斗全球卫星导航系统正式开通并投入使用后,可为全球用户提供全天候定位服务。我国的交通网络中存在很多隧道,这些隧道的空间狭小、且整体封闭,传统的导航条件下一旦车辆进入隧道中,信号被削弱或者屏蔽,导致定位导航服务效果不佳。在技术高速发展的今天,北斗卫星导航技术在隧道内定位中凸显了其优势。基于此,文章重点分析了隧道内定位中北斗卫星导航技术的应用,以期助力推广该技术。After the arrival of the information era,the application scope of navigation technology has significantly expanded,especially after the Beidou Global Satellite Navigation System has been officially launched and put into use,it can provide round-the-clock positioning services for global users.There are many tunnels in China's transportation network,which are narrow in space and generally closed.Under traditional navigation conditions,once vehicles enter the tunnel,the signal is weakened or shielded,often resulting in poor positioning and navigation services.Today,with the rapid development of technology,Beidou satellite navigation technology highlights its advantages in positioning in tunnels.Based on this,this article focuses on analyzing the application of Beidou satellite navigation technology in tunnel positioning,with a view to promoting this technology.
