Abstract
The ASG-EUPOS network - the active geodetic network was established in Poland in 2008. The 2010/2011 campaign was the second one managed to integrate the ASG-EUPOS network with the first order national geodetic networks in Poland. As the result the station coordinates were determined in the uniform coordinate frame. The paper describes the measurements carried out for data acquisition as well as the data processing method. The results present analyses of differences between selected variants of solutions and show some problems encountered during the calculation.
