摘　　要：我国高精度定位产品正处在规模推广阶段,急需提出一套能够评价高精度定位产品服务质量的指标体系,并结合实际应用场景提供实际测试数据为行业应用提供参考。本文介绍了高精度定位技术原理,对影响产品服务质量的因素进行拆解,通过对行业客户调研给出了服务质量的测评指标体系建议与客户实际需求门限。选取了近50 km的城市道路和若干定点对主流北斗高精度定位产品的服务质量展开测评。最后针对过街天桥、立交桥、短隧道和连续树荫等复杂场景带来的服务质量降低进行量化分析,并给出了终端布放位置周边场景尽量开阔、结合雷达和图像等其它定位技术手段和分场景使用不同天线以提高定位精度的建议。With the development of China's BeiDou navigation industry and the mature construction of BeiDou satellite global networking,BeiDou positioning are in the stage of scale promotion in industries.Therefore,data support is urgently needed to truly reflect the service quality of BeiDou positioning and provide reference for industry applications.This paperfirst introduces the principle of BeiDou positioning technology,disassembles the factors affecting the quality of services,and gives the evaluation index system suggestions for service quality and the actual demand threshold of customers.Secondly,nearly 50km of urban roads and severalfixed points were selected to evaluate the service quality of mainstream BeiDou positioning products.Finally,this paper quantitatively analyzes the service quality reduction in complex scenes such as overpasses,overpasses,short tunnels and continuous shade trees.In addition,the surrounding scene of the terminal layout is as wide as possible,and the suggestions are given to use different antennas in different scenes to improve the positioning accuracy in combination with other positioning techniques such as inertial navigation,radar and image.
