GNSS拟合高程代替水准测量的可行性分析:以黄河上游水电基地区域为例

Feasibility analysis of GNSS fitting elevation instead of leveling measurement:Taking the hydropower base area in the upper reaches of the Yellow River as an example

GNSS拟合高程代替水准测量有重要的现实意义,有必要对其进行可行性分析。黄河上游水电基地是中国在黄河上游地区开发的重要水利工程群,其安全监测具有至关重要的作用。因此,本文基于黄河上游水电基地GNSS自动监测网开展实验,从GNSS高程拟合方法、GNSS数据处理策略和GNSS高程方向定位结果等方面详细论证。结果表明,GNSS拟合高程具有替代三等水准的可行性。

GNSS fitting elevation instead of leveling measurement has important practical significance,and it is necessary to analyze its feasibility.The safety monitoring of hydropower plants in the upper reaches of the Yellow River plays a crucial role.Therefore,this article conducts experiments based on the GNSS automatic monitoring network of the hydropower plants in the upper reaches of the Yellow River,and elaborates on the GNSS elevation fitting method,GNSS data processing strategy,and GNSS elevation direction positioning result in detail.The result indicate that GNSS fitting elevation has the feasibility of replacing third order leveling.
