Precise GPS for Integrated Marine Gravity Acquisition

A.H. Dodson, T. Moore and W. Chen, H. Oehl and P. Houghton

Abstract:	The vertical acceleration of the vehicle is one of the main error sources in gravity surveys on a moving platform (marine and airborne). GPS is not sensitive to gravity and so is an ideal method of measuring the vertical acceleration of the platform [1]. In this paper, the principle of a new gravity survey system that integrates a marine gravimeter and GPS is described. A land experiment was carried out to test the measurement accuracy of the integrated system. The results of this experiment are analysed in this paper. It demonstrates that gravity measurements with an accuracy of 0.6 mgal can be achieved with this integrated system, in a dynamic environment.
