Abstract: Since the satellite systems have been operative, the data from permanent stations have been used for modelling the changes of the coordinates of the stations. One of the components of the changes is the change of the location of the Earth’s crust surface. Both horizontal and vertical changes are analysed, as well as their velocities are determined. The system of ASG EUPOS station has been operative in Poland since 2008. The longer the system operates, the more possible it will be to create a model of the vertical crustal movements on Polish territory. The vertical movements can be determined as absolute, or relative. In order not to include the influence of transformation errors, the changes of geoid and eustasic, the changes of velocity between the chosen ASG EUPOS stations can be used to the creation of the model. The purpose of this article is to determine various models of the relative vertical movements from satellite data, as well as their evaluation. The author of the article concentrated mainly on the determination of the relative velocities, on their equalisation and visualisation. Relative vertical movements between the stations were determined on the basis of various data and for various epochs. They were equalised in several versions. As a result, several models of relative vertical movements were created and evaluated. In addition, there were established the accuracy possibilities of determining the model of the relative vertical movements on the basis of the data from ASG EUPOS.
