We give an overview of time series analyses of permanent GPS stations using solutions of the IGS and FinnRef® networks. Lomb periodograms show in most cases a statistically significant annual period both in station coordinates and inter-station dist

Five different geoid models are analysed to estimate the possible error budget of new global geoids based on the data from the gravity satellites CHAMP, GRACE and GOCE. We used the global models OSU91A and EGM96, the European model EGG97, the Nordic

We have computed GPS time series of different resolutions in the Finnish permanent GPS network FinnRef. In the Lomb periodigrams we can distinguish an annual period (Makinen et al. 2000) but also a diurnal period. The annual period is visible in all

The Finnish Geodetic Institute has established a network of 12 permanent GPS-stations in Finland (FinnNet). The planning of the network started during winter 92/93. The first stations were installed in 1994 and the last one was built in the autumn of

GPS levelling was used in two test areas in Finland in order to investigate the capability of GPS measurements for orthometric height determinations. Both test areas are surrounded by the spirit levelling loops of the Precise Levelling network. Besid
