High-precision astrogeodetic vertical deflections in Germany are utilized to validate recent satellite-only global gravity field models with emphasis on the first- and second-generation GOCE models. In order to account for the different spectral characteristics of the data sets involved, the comparisons are performed with a multistage filtering procedure. The comparisons demonstrate that the second generation of GOCE models is significantly improved (by roughly 30 %) compared to the first release, and that the GOCE models contain considerably more gravity field information than pure GRACE models.
