Regional Astrogeodetic Validation of GPS/Levelling Data and Quasigeoid Models

In the context of a GOCE regional validation and combination experiment in Germany, a work package within the framework of the GOCE-GRAND II project, gravity observations, vertical deflections and GPS/levelling data are collected as independent data sets. The observation of absolute gravity values i...
