摘　　要：随着北斗导航定位系统的全球组网完成,北斗终端发展迅速,已经广泛应用于无人机、新能源汽车、智能机器人等多个领域,然而,对北斗终端动态定位精度缺少有效检测工具,北斗终端检测能力亟需加强。现有检测手段(例如基线场)只能检测静态情况下北斗终端的定位精度,无法评估北斗终端动态定位精度。为了更好地评估北斗终端动态定位精度,提出了一种用于北斗终端动态检测系统,通过构建车载北斗/INS组合导航动态基准,辅以CORS基准站静态基准,提出了一种动态检测方法,并通过实际路测的方式,实现为北斗终端动态检测提供基准,可以为北斗终端提供厘米级精度的检测。通过实际测试,证明了系统可以检验厘米级导航终端的定位精度,为北斗终端动态定位精度检测提供了有效手段。With the completion of the global networking of the Beidou navigation and positioning system,the Beidou terminal has developed rapidly.The Beidou terminal has been widely used in many fields such as drones,new energy vehicles,and intelligent robots.However,the dynamic positioning accuracy of the Beidou terminal lacks effective detection tools.,Beidou terminal detection capabilities urgently need to be strengthened.Existing detection methods such as the baseline field can only detect the positioning accuracy of the Beidou terminal under static conditions,and cannot evaluate the dynamic positioning accuracy of the Beidou terminal.In order to better evaluate the dynamic positioning accuracy of the Beidou terminal,this paper proposes a dynamic detection system for the Beidou terminal.By constructing a dynamic benchmark for the vehicle-mounted Beidou/INS integrated navigation,supplemented by a static benchmark for the CORS reference station,a dynamic detection method is proposed,and through actual road testing,it can provide benchmarks for Beidou terminal dynamic detection,and can provide centimeter-level accuracy testing for Beidou navigation and positioning terminals.Through actual tests,it has been proved that the system can verify the positioning accuracy of centimeter-level navigation terminals.The terminal dynamic positioning accuracy detection provides an effective means.
