Optimization Computation of the Etvs Correction in Marine Gravimetry
2011
The accuracy of the Etvs effect correction is the most important factor that affects the precision of marine gravity survey.To decrease the error of Etvs correction value,we put forward the track fitting,calculation of the course and ship speed with reasonable method and Etvs correction filtering in this paper.By theoretical analysis and actual calculation,we confirmed the validity of the method.
