Higher accuracy requirements for results of GPS measurements (mainly for geodynamic purposes) introduce a problem of determination of phase centres of used GPS antennas. The method of field calibration with rotation of the antenna is a suitable compromise between financial requirements and accuracy of results. This method was applied to antennas used in the GPS permanent service at the GOPE station, Czech Republic. Results were used to explain some phenomena in time series of the station coordinates. Jumps in horizontal components of the time series were explained by differences in phase centres` positions. An introduces milimetre differences in phase centres` positions and the snow induces centimetre changes in the vertical component of phase centres` positions.
