Preliminary geoid mapping results by Fugro’s improved Micro-g LaCoste turnkey airborne gravity system

In this paper, we introduce the Micro-g LaCoste Turnkey Airborne Gravity System (TAGS) with Fugro’s improved gravity processing and geoid modeling software package for regional gravity field mapping and geoid determination. Three test areas with different topographic characteristics under the Gravity for the Redefinition of the AmericanVertical Datum (GRAV-D) project of theUSNOAA National Geodetic Surveys (NGS) were used for case studies and determine the available accuracy of the system. The preliminary results of all these test cases show that the system with Fugro’s improved gravity and geoid processing software package is able to achieve a comparable geoid mapping result to traditional terrestrial methods.
