Short-Period Information in GPS Time Series

This paper presents results of the Polish Active Geodetic Network (ASG-EUPOS) processing. The analyses on the GPS coordinates from sub-diurnal solutions of ASG-EUPOS and EPN data provided by Warsaw Military University of Technology were performed. The aim of this research is to find out how the tidal models used in Bernese software (solid Earth and ocean tides as well) fit to the individual conditions of GPS stations. The 1-hour solution technique of GPS data processing was utilized to obtain coordinates of above 130 Polish and foreign stations. This processing technique allowed us to recognize residual diurnal and sub-diurnal oscillations which could be next utilized for validation of the tidal models used in GPS software.
