摘要
采用控制变量法,对比分析了网络RTK服务在不同环境下的性能差异。在多个典型场景下,通过采集流动站数据,并利用RTKLIB软件联合不同RTK服务商的虚拟参考站改正数进行了解算。实验结果显示,在非极端环境下,网络RTK服务能提供稳定且高精度的定位;但在遮挡严重的“城市峡谷”等环境下,由于GNSS信号受到较大干扰,网络RTK的定位性能显著降低,无法满足高精度需求。因此,对于坐标精度要求较高的应用,建议在遮挡严重环境下谨慎使用或结合其他观测手段。
This paper adopts the controlled variable method to comparatively analyze the performance differences of Network RTK services in different environments.In several typical scenarios,data from rover stations was collected,and RTKLIB software was utilized to jointly calculate the virtual reference station corrections from different RTK service providers.Experimental results indicate that,in non-extreme environments,Network RTK services can provide stable and high-precision positioning.However,in environments with severe occlusion,such as“urban canyons”,due to significant interference with GNSS signals,the positioning performance of Network RTK is significantly reduced,making it unable to meet high-precision requirements.Therefore,for applications requiring high coordinate accuracy,it is recommended to use caution or combine with other observation methods in heavily occluded environments.The research findings provide some reference and guidance for the application of Network RTK technology in different environments,and have certain reference significance for scientific research and construction in related fields.
