Abstract: Permanent GPS sites in Denmark and the surrounding country’s are used in order to study crustal deformations. The Danish GPS sites have been operating since early 1999 and more than 3 years of continuous GPS data is available. Using the Bernese software, we have calculated daily baseline solutions between the selected GPS sites. The time series of the baseline solutions are then used in order to calculate relative three-dimensional crustal motions (vertical and horizontal). The time series are analysed for post glacial rebound. The observed relative motions due to glacial updrift are consistent with modelled adjustments of the glacial isostatic of Fennoscandia. The glacial rebound modelling is carried out by [Milne et al., 2001]. Figure 3: Modelled postglacial rebound (Milne model)
