COMBINATION OF DIFFERENT SPACE GEODESY TECHNIQUES FOR EOP AND TERRESTRIAL REFERENCE FRAME DETERMINATION

The combination method of results of different space geodetic techniques gives two kinds of products. On the one hand, the Earth orientation parameters (EOP) that define the orientation of the Earth in space and, on the other, the coordinates of collocation stations by them the ITRF is realized. Obtained results are based on the method developed by authors, so called "non-rigorous" combination of the data. Approximately eight-year data was successively processed in order to obtain solutions of both products, which were then compared with the results given in ITRF 2005 solution.
