| Abstract: | The observation data of the crustal movement observation network base sta tions ars selected, two groups total zenith delays are calculated in two case of taken into ac count and disregard of the ocean tide correction model, and comparative analysis is presented. In the same time, the characteristics of frequency and amplitude are analyzed,more about the impact of ocean tide on the total zenith delay observations of groundbased GNSS is studied, and useful conclusions are summed up. |

| Keywords: | GNSS ocean tide models total zenith delay (ZTD) GAMIT/GLOBK |
