Abstract:The Eotvos correction in offshore gravity survey depends on the relationship of ship' s navigation}pasitioning data. In order to reach expected accuracy of offshore gravity survey, we must see that the high precision navigation positioning system should be included in the major instruments used in offshore gravity survey except that the essential accuracy of offshore gravity meter is guaranteed. In this paper, examples are given to show haw to calculate from navigation positioning data the required variables and corresponding RMS errors which are used to work out Eotvos corrections, and the geographic coordinates of every gravity station.
