| Abstract: | This paper analyzes the Earth tide and ocean loading tide in the absolute gravity measurements at the coastal fiducial station, and the accuracy statistics calculated by the different tide models, the resuhs indicate the correction of the absolute gravity measurements near the ocean by the global ocean models are not very accurate. And the ocean loading tide correction of the relative gravity measurements are analyzed. |
