The data of airborne gravimetry measurement is easily interfered by the dynamic movement of planes,and the quality of the data of airborne gravimetry will also decline when the dynamic movement of planes is strong.Through digital filtering, most of the noises in gravity anomaly data can be removed.However,a part of noises overlapped with useful signals cannot be wiped out.Using empirical mode decomposition,we can process a group of measured data in depth which have great influence on dynamic movement of planes.The result indicates that the dynamic errors caused by the dynamic movement of planes could be eliminated without affecting the data resolution of airborne gravity anomaly,thus enhancing the internal accord accuracy from 1.43 to 1.27 mGal.
