Abstract

A comparison for the marine gravimeters on the same vessel was carried out between SAG-2M marine gravimeter developed by China and KSS31M marine gravimeter designed by Germany in order to test the technical performance and data reliability of SAG-2M marine gravimeter. The raw gravity data acquired from these two marine gravimeters were preprocessed according to the standards of marine geologic survey to obtain the free air gravity anomalies, and the comparison and relativity for those two types of gravity data were studied by analyzing the cross-point differences, survey lines and grid data. The result shows that the SAG-2M marine gravimeters have the same level of measurement accuracy with the KSS31M marine gravimeter because there is a highly linear relationship between the data from two marine gravimeters with an approximately similar variation trend. Based on the results of comparison, it is concluded that the self-developed SAG-2M marine gravimeter shares the similar standard of measurement accuracy with the KSS31M marine gravimeter with a stabilized technical performance, which provides an important reference for the future application of SAG-2M marine gravimeter.

Key words： SAG-2M marine gravimeter KSS31M marine gravimeter comparison on the same vessel technical performance measurement accuracy
