摘要
以基岩GNSS连续观测站为背景,考察各土层GNSS连续观测站垂直、水平分量的变化特征。观测结果表明,排除沉降干扰,严重沉降站一般需要改正,一般沉降站视研究需要决定是否改正。最后给出受沉降影响的测项的改正方法。
In this paper,we take rock-based GNSS continuous stations as referents,and inspect the observed deformation variations in both horizontal and vertical components of every soil-based GNSS continuous station.Observations show that severe subsidence stations must be corrected,slight subsidence stations should be corrected depending on the research goals,and no correction is needed on non-subsidence stations for continuous GPS observations.We also present some methods for subsidence correction on GNSS station observations.
