| This International Association of Geodesy (IAG) Special Study Group aims to develop the theoretical basis and methods required for the production of a synthetic model of the Earth's gravity field for use in physical geodesy. Geodetic gravity field researchers have previously tended to rely on analytical error estimates, often based on observed data. Moreover, many of the discrepancies between the various theories used are at the limit prescribed by the current data availability. Therefore, a synthetic gravity model will avoid these scenarios and give a largely independent validation of the procedures used. |
