Abstract
Over the last decade, there has been an increased interest in the determination of the geoid. This is mainly due to the demands for height transformation from users of GPS. Costly conventional levelling operations can be replaced with quicker and cheaper GPS-levelling surveys, as long as the geoidal height is computed to a high accuracy. Therefore, there is a common goal among geodesists to determine “the 1-cm geoid model”. This study uses a least-squares procedure to compute the modification parameters for the geoidal height determination over Norway. For the computation of the long-wavelength contribution, the new Global Geopotential Models (GGM) GGM01s from GRACE twin-satellites is used.
