恶劣环境下GPS-RTK实际定位精度测试

GPS-RTK actual positioning accuracy test under the rough environments

本文主要是通过高级别测量结果与恶劣环境下GPS-RTK测量三维坐标的精度水平进行比较,利用MATLAB软件对恶劣环境下GPS-RTK的实际定位精度做一个系统分析,通过分析得出:针对本次实验,树荫下GPS-RTK的实际定位精度为米级,高压线与楼脚下GPS-RTK的实际定位精度为厘米级;恶劣环境下GPS-RTK固定解的实际定位精度可以达到5厘米,并且精度稳定可信;恶劣环境下GPS-RTK浮动解得实际定位精度为米级,并且精度不稳定,不可信。

This article is to compare the level of accuracy through high-level measurements and the threedimensional coordinates of GPS-RTK in the rough environments. MATLAB software is used to make a systematic analysis for the GPS-RTK positioning accuracy in the rough environment. For this experiment through the analysis it have been draw that the GPS-RTK positioning accuracy under the shade is meterscale, and the GPS-RTK positioning accuracy at the foot of high-voltage lines and the floor is centimeterlevel. The positioning accuracy of GPS-RTK fixed solution in rough environment can reach 5 cm, and the stability of accuracy can be trusted. The positioning accuracy of GPS-RTK float solution in rough environment is meter-scale, and the stability of accuracy cannot be trusted.
