“…Each subsequent realization of ITRF is considered as a refinement of the previous one. In this case, for the first time in history, ITRF was generated with the modeling of a non-linear station's movements, including seasonal (annual and semi-annual) station position signals and post-seismic deformation for objects that have suffered major earthquakes (Altamimi et al, 2016;Figurski and Nykiel, 2017). In parallel with the introduction of ITRF2014, updated PCC models of both receivers and satellites (igs14.atx) were released.…”

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.

“…By this means, the reconstructed NEQ fully inherits the geometrical correlations of the GPS stations in the CMONOC network, and datum orientation and scale information defined by the fixation of the GPS satellite orbits and the Earth rotation parameters in the processing of CMONOC data on Bernese, and is thus adequate to compute the solution of station positions by applying NNT MCs. Naturally, the inherited datum information should rely on the TRF of the GPS satellite orbits, and even on the antenna phase center calibration (PCC) models for the satellites and the receivers [37].…”

High-precision GPS data processing on Bernese has been employed to routinely resolve daily position solutions of GPS stations in the Crustal Movement Observation Network of China (CMONOC). The rank-deficient problems of the normal equation (NEQ) system and the network effect on the frame alignment of NEQs in the processing of CMONOC data on Bernese still present difficulties. In this study, we diagnose the rank-deficient problems of the original NEQ, review the efficiency of the controlled datum removal (CDR) method in filtering out the three frame-origin-related datum contents, investigate the reliabilities of the inherited frame orientation and scale information from the fixation of the GPS satellite orbits and the Earth rotation parameters in establishing the NEQ of the CMONOC network on Bernese, and analyze the impact of the network effect on the position time series of GPS stations. Our results confirm the nonsingularity of the original NEQ and the efficiency of the CDR filtering in resolving the rank-deficient problems; show that the frame origin parameters are weakly defined and should be stripped off, while the frame orientation and scale parameters should be retained due to their insufficient redefinition from the minimal constraint (MC) implementation through inhomogeneous and asymmetrical fiducial networks; and reveal the superiority of a globally distributed fiducial network for frame alignment of the reconstructed NEQs via No-Net-Translation (NNT) MC conditions. Finally, we attribute the two apparent discontinuities in the position time series to the terrestrial reference frame (TRF) conversions of the GPS satellite orbits, and identify it as the orbit TRF effect.

“…The point positions using SP60 were determined in ETRF2000 (R05) (epoch 2000) coordinate system. It was necessary to transform coordinates to ITRF2008 (epoch 2017), in order to compare with PPP/RTK results [19]. Furthermore, to make a more advanced analysis of the data, the networks were measured with the usage of another GNSS receiver (not supporting RTX technology) -Geomax-Zenith 25.…”

In this paper, authors present results of accuracy verification of the Trimble RTX technology. The GNSS receiver Spectra Precision SP60 was used in Cyprus (Kato Paphos Archaeological Park). To evaluate the accuracy of the receiver, two measuring test networks (consisting of 30 and 55 control points) were established. All points were determined in four measuring cycles. Additionally, in order to make more advanced analysis of the data, the bases were also measured by using another GNSS receiver - Geomax-Zenith 25. The point positions, in this case, were conducted in the local coordinate system of Kato Paphos Archaeological Park by using RTK positioning technology. To make a comparison, it was necessary to transform the coordinates based on different groups of fitting points. Analysis allowed to conclude that the Spectra Precision SP60 receiver and the RTX Trimble technology guarantee repeatable results (on the level of 4 cm) of point positioning measurements.
