“…Our computations were performed on the basis of an improved solution of the International Terrestrial Reference Frame ITRF2008, adjusted and described in detail by (Altamimi et al 2011). The geodetic coordinates (u, k, h) for DORIS beacons are transformed from (x, y, z) according to the expressions described in (Heiskanen and Moritz 1981). The station coordinates, velocities caused by the tectonic plate motions for SLR, GPS, DORIS and VLBI techniques were taken from the ITRF2008.…”

This paper concerns an analysis of the accuracy of the estimated parameters X (U, K, x) which define the tectonic plate motions. The study is based on the velocities of station positions in the IERS (International Earth Rotation and Reference Systems Service) which has published new realization of the International Terrestrial Reference System-ITRF2008 for Doppler Orbitography by Radiopositioning Integrated on Satellite DORIS technique. Eurasian, African, Australian, North American, Australian, Pacific, Antarctic and South American plates were used in the analysis. The influence of the number and localization of stations on the plate surface on the estimation accuracy of the tectonic plate motion parameters were discussed. The results were compared with the APKIM 2005 IGN model and our earlier estimation for the SLR technique. In general, a remarkable concurrent agreement between the present and the APKIM 2005 solutions was found.

“…Another factor that influences the accuracy of the solution is the geometrical configuration of the station network, which has been explained in [ 14 , 17 ]. Consistency with the previous determination of the Φ, Λ, and ω parameters for the SLR [ 37 , 38 ], DORIS [ 38 , 39 ], and VLBI [ 38 , 40 ] techniques were maintained, and the same manner of selecting stations was used. These assumptions were created based on the tests conducted during the realisation of previous studies.…”

“…The method also allows for data optimisation, i.e., specifying the minimum number of stations on the given tectonic plate for which the calculated motion parameters are stabilised (i.e., their changes do not exceed the value of formal errors). To date, studies have been carried out on the SLR [ 37 , 38 ], DORIS [ 38 , 39 ], and VLBI [ 38 , 40 ] techniques and, on the GNSS technique, for the Eurasian plate [ 41 ]. In this study, the subsequent stage of the conducted studies is presented.…”

Current knowledge about tectonic plate movement is widely applied in numerous scientific fields; however, questions still remain to be answered. In this study, the focus is on the determination and analysis of the parameters that describe tectonic plate movement, i.e., the position (F and L) of the rotation pole and angular rotation speed (w). The study was based on observational material, namely the positions and velocities of the GNSS stations in the International Terrestrial Reference Frame 2014 (ITRF2014), and based on these data, the motion parameters of five major tectonic plates were determined. All calculations were performed using software based on a least squares adjustment procedure that was developed by the author. The following results were obtained: for the African plate, Φ = 49.15 ± 0.10°, Λ = −80.82 ± 0.30°, and ω = 0.267 ± 0.001°/Ma; for the Australian plate, Φ = 32.94 ± 0.05°, Λ = 37.70 ± 0.12°, and ω = 0.624 ± 0.001°/Ma; for the South American plate, Φ = –19.03 ± 0.20°, Λ = −119.78 ± 0.39°, and ω = 0.117 ± 0.001°/Ma; for the Pacific plate, Φ = −62.45 ± 0.07°, Λ = 111.01 ± 0.14°, and ω = 0.667 ± 0.001°/Ma; and for the Antarctic plate, Φ = 61.54 ± 0.30°, Λ = −123.01 ± 0.49°, and ω = 0.241 ± 0.003°/Ma. Then, the results were compared with the geological plate motion model NNR-MORVEL56 and the geodetic model ITRF2014 PMM, with good agreement. In the study, a new approach is proposed for determining plate motion parameters, namely the sequential method. This method allows one to optimize the data by determining the minimum number of stations required for a stable solution and by identifying the stations that negatively affect the quality of the solution and increase the formal errors of the determined parameters. It was found that the stability of the solutions of the F, L, and w parameters varied depending on the parameters and the individual tectonic plates.
