     abstract = "{Global geopotential models (GGMs) are vital in computing global geoid
        undulations heights. Based on the ellipsoidal height by Global
        Navigation Satellite System (GNSS) observations, the accurate
        orthometric height can be calculated by adding precise and
        accurate geoid undulations model information. However, GGMs also
        provide data from the satellite gravity missions such as GRACE,
        GOCE and CHAMP. Thus, this will assist to enhance the global
        geoid undulations data. A statistical assessment has been made
        between geoid undulations derived from 4 GGMs and the airborne
        gravity data provided by Department of Survey and Mapping
        Malaysia (DSMM). The goal of this study is the selection of the
        best possible GGM that best matches statistically with the geoid
        undulations of airborne gravity data under the Marine Geodetic
        Infrastructures in Malaysian Waters (MAGIC) Project over marine
        areas in Sabah. The correlation coefficients and the RMS value
        for the geoid undulations of GGM and airborne gravity data were
        computed. The correlation coefficients between EGM 2008 and
        airborne gravity data is 1 while RMS value is 0.1499.In this
        study, the RMS value of EGM 2008 is the lowest among the others.
        Regarding to the statistical analysis, it clearly represents
        that EGM 2008 is the best fit for marine geoid undulations
        throughout South China Sea.}",
