    • Abstract
  • Based on the linear relation between the cross-coupling correction and 5 cross-coupling monitors,the method for modifying the coefficient of every surveying line were obtained.The method is divided into two steps.Firstly,based on the adjustment principle the coefficients of 5 cross-coupling monitors of every surveying line are modified at junction points.Secondly,cross-coupling correction is calculated using the new coefficients.Experimental results show that the new coefficients can compensate the influences made by the differences between actual dynamic surveying-conditions and tentative surveying-conditions designed by meter factory for calculating cross-coupling coefficients,and can obtain better cross-coupling correction.The data accuracy of marine gravity surveying can be improved with the method proposed.
