%X Satellite gravity gradient data reduction and gridding are indispensable steps for recovering the Earth's gravity field with space-wise method.The second-order radial correction formula for gravity gradient data reduction is given,and the results show that the use of high-precision reference gravity field model can effectively reduce the reduction errors.The gridding accuracy and applicability of weighted average method,Shepard surface fitting and least squares collocation method are compared.As a test,the ...
