摘　　要：针对当前网络中无线网络优化无法准确定位的问题,本文利用轨道经纬度信息和软采的MR数据实现轨道网络无线问题点的分析及捕捉,结合GIS呈现,形成一套分析定位整体解决方法。其中使用了交点算法,利用TA和AoA结合轨道的经纬度进行质差点定位,同时结合软采数据和网络爬虫的轨道经纬度数据,通过GIS地图直观呈现无线问题点。实验测量结果显示这种基于交点算法的网络质差定位法能达到20m内定位精度90%以上,优化效果明显。In view of the problem that the wireless problem in the current network cannot be accurately located,a solution has been proposed that by using the latitude and longitude information of the track and the soft MR data,and combines the GIS to analyzes and captures the wireless problem points of the orbit network.The intersection algorithm has been used to perform the quality difference point positioning which combined TA,AoA and the latitude and longitude of the orbit.Combined with the latitude and longitude orbital data soft data mining and web crawler,through GIS maps visualize wireless problems.Finally,experimental results show that poor quality network-based positioning method intersection algorithm can achieve positioning accuracy of more than 90%by 20 m,the optimization effect is obvious.
