千寻北斗地基增强系统在滑坡监测的应用

The application of Qianxun BeiDou ground-based augmentation system in landslide monitoring

2016年5月18日,千寻北斗地基增强系统在我国正式开始运营,标志着我国北斗卫星定位系统的又一次重要突破。本文研究千寻北斗地基增强系统在滑坡监测中的应用前景。通过在三峡地区的滑坡监测,分析比较了基于北斗地基增强系统和传统GNSS单基站RTK定位精度。结果表明:基于北斗地基增强系统的观测方式和单基站-观测站的观测方式,都可以得到优于1 cm的平面监测结果,但是前者明显提高了观测效率,降低了观测成本。这一结论对于千寻北斗地基增强系统在滑坡监测方面的应用有一定的借鉴意义。

On May 18,2016,Qianxun Beidou ground-based augmentation system was officially put into operation in China,marking another important breakthrough of Bei Dou satellite positioning system.This paper studies the application prospects of Qianxun Bei Dou ground-based augmentation system in landslide monitoring.Through landslide monitoring in the Three Gorges area,the comparison between the augmentation system and the traditional GNSS single base station based RTK positioning accuracy is carried out.The results show that both methods can obtain<1 cm horizontal accuracy,but the Beidou Ground-based augmentation system can obviously improves efficiency and reduces the observation cost.This conclusion can be used as a reference for the application of Qianxun Bei Dou foundation reinforcement system in landslide monitoring.
