| Abstract: | Marine gravity measurement data contains the centrifugal force on the ground produced by the motion of surveying vessels, and the earth centrifugal force is related to the latitude. According to the principle, this paper gives the method for measuring the centrifugal force to calculate the latitude directly, and gives the best method after analysing the measurement accuracy. In the calculation examples, the method is effective for measuring the latitude of survey points. |
