高精度差分定位技术启动时间和精确度比较分析

Comparative Analysis of High-precision Differential Positioning's Start-up Time and Accuracy

我们修改了rtklib开源软件,利用NovAtel、Ublox接收机,对不同的基站、移动站接收机组合,统计分析在不同基线距离的情况下,高精度差分定位的启动时间和定位精确度。对比在不同基线长度下高精度差分定位技术的启动时间差别、定位精度和准确度的变化,填补目前文献上这一部分数据的空白,为高精度差分定位技术的应用提供参考。

We enhanced the open source rtklib software. With the receivers of NovAtel and Ublox, we statistically analyze the high-precision differential positioning start-up time and accuracy for the different receiver combinations of base and rover station, in the different baseline distance. We compared to different baselines and the change of the start-up time and the positioning accuracy of the high-precision differential positioning technique. This work provides first systematic study of RTK accuracy over the different receivers and different baselines. It is useful for the applications of high-precision differential positioning technology.
