Description:

Changes in the position of the GNSS receiver antenna phase centre are still one of the dominant error sources associated with the measuring station. The preferred method of solving the problem is modeling antenna phase centre variations (PCV). Such models are available in igs05.atx, igs08.atx or igs14.atx files, among others. Due to different methods of antenna calibration (chamber calibration, relative field calibration, absolute field calibration) and different types of models (mean, individual), depending on the GNSS observation processing product used, there may occure differences in the estimated parameters, including station coordinates. In this paper, the results of GNSS observation processing using the models included in the igs08.atx and igs14.atx files for 12 EPN and ASG-EUPOS stations were analysed, both for daily and sub-daily time series of PPP solutions. The obtained results show that switching from the igs08.atx to igs14.atx (for the selected stations) induces differences in the vertical component, reaching up to ± 3 mm.
