Abstract: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.
