Common Experiment of the Analysis Centre CODE and the Institute of Geodesy and Geodetic Astronomy of Warsaw University of Technology (IGGA WUT) on the Combination of Regional and Global Solutions
Since January 1995 the CODE Processing Centre and the Institute of Geodesy and Geodetic Astronomy of Warsaw University of Technology entered into cooperation aimed at testing different processing methods for the Polish network consisting of 3 permanent IGS stations: Józefosław, Borowiec and Lamkówko. The connection to the global reference frame is realised by processing 4 additional European IGS stations: Wettzell, Kootwijk, Metsahovi and Onsala. The results of four different processing strategies are compared with the results achieved by CODE from the global network. The experiment is a practical test of the idea of IGS regional data processing expected for IGS Associated Analysis Centre Type I. Particular attention is paid to the impact of the orbits (CODE vs.IGS) and the influence of the troposphere parameter estimation on the station coordinates. Since end of March 1995 the second receiver a TURBO ROGUE SNR 8000, was included into the permanent network. The results of data processing using the same computation strategies as well as results of the combination with the global solution are shown. The preliminary results of this work are shortly reported in the paper. The experiment of combining global CODE solutions with regional solutions was also tested with the EXTENDED SAGET’94 Network.
