The solid-earth-tide models IERS1992 and IERS2003 are used to analyze some GPS-baseline, vertical-component and zenith-tropospheric-delay data from the Crustal Movement GPS Continuous Observation Network of Shandong and IGS stations. The results show that the differences between the baselines computed with the different models are at sub-millimeter level, and the differences in vertical component is direct proportional to station latitude. Also the amplitude of ZTD differences is about 0.6-1.0 mm, which is 6%-8% of the amplitude of solid-earth-tide differences. Although these effects are quite small, to analyze non-tidal deformation correctly, we should still use a single standard for processing GPS data. |
