摘　　要：常见的网络定位技术主要有GNSS定位、基站定位、WiFi定位三种,每种定位技术都有其应用的场景和优缺点。现有的定位性能评估方法因涉及较专业的实验室设备,存在设备采购和维护成本高、场景覆盖较少等问题。本文提出了一种基于多用户协同的网络定位性能评估方法,该方法通过多用户手机协同机制采集大量高精度的GNSS基准位置评估基站或WiFi等粗精度网络定位性能,文章分析了该方法的实现流程,并通过试验场景和数据分析对比,最终给出了评价。There are three common network positioning technologies,GNSS positioning,base station positioning and Wi Fi Positioning.Each positioning technology has its application scenarios,advantages and disadvantages.The existing location performance evaluation method involves very professional laboratory equipment,which has the problems of high cost of equipment procurement and maintenance,less scene coverage and so on.This paper proposes a method of network location performance evaluation based on crowd-sourcing,analyzes the implementation process of this method,and analyzes its evaluation performance through experimental data.
