摘要:

随着我国北斗导航产业的发展与北斗卫星全球组网的成熟建设,5G+北斗高精度定位服务在如测量测绘、形变监测、驾考驾培、自动驾驶等行业的应用正处在规模推广阶段。行业客户对高精度定位产品服务质量评估的需求也逐渐显现,现有的评估方法侧重在基准站、接收机终端侧,无法为行业用户所有使用或选择高精度定位服务提供参考。因此,需要一套面向行业应用的高精度定位服务质量评价体系为行业应用提供参考。创新性地提出了一套评估指标体系,特别是结合3GPP Release17定义及车企等行业客户需求,搭建了完整的类指标体系,并在全国范围的不同区域、不同场景进行了验证。最后,通过对大量数据结果进行处理分析,以及对动态遮挡场景的影响、高精度定位平台与终端适配等用户侧更为关注的方面进行了分析,给出了服务质量改善的优化建议。特殊地,对比分析了单北斗条件下的服务质量。

Abstract:

With the development of Beidou navigation industry and the mature construction of Beidou satellite global networking, the application of 5G+ Beidou high-precision positioning services in industries such as surveying and mapping, deformation monitoring, driving test driving training, and automatic driving is in the stage of large-scale promotion.The demand for high-precision positioning product service quality evaluation from industry customers is gradually emerging.The existing evaluation methods focus on reference stations and receiver terminals, which cannot provide reference for industry customers in using or how to choose high-precision positioning services.Therefore, a high-precision positioning service quality evaluation system for industry applications is needed to provide reference for industry applications.A set of evaluation index systems was innovatively proposed, especially combining the definition in 3GPP Release17 and the needs of industry customers such as automotive companies, to build a complete category index system, and it was verified in different regions and scenarios nationwide.By processing a large amount of data results, the impact of masking environment on terminal devices in dynamic movement, high-precision positioning platforms, and terminal adaptation, which were more concerned by industry users, were analyzed, and optimization suggestions for improving service quality were provided.In addition, the service quality under the condition of single Beidou was compared and analyzed.

Key words: 5G, high-precision positioning, test scheme, poor quality reason
