Abstract: In order to eliminate the disturbance of different kind of errors,we propose an integrated method with two steps for compensating the systematic errors of marine and airborne measurements from L&R gravimeter.Firstly,crosscorrelation analysis is used to make corrections for the original cross-coupling correction coefficients obtained from the instrument manufacture,and give a systematic correction to the observed gravity.Then surveying line system adjustment is applied to the corrected gravity to further eliminate the disturbance of remainder errors.A practical marine gravity measurement set is used to prove the efficiency of the integrated data processing method.
