Information × Registration Number 0205U007153, 0101U007476 , R & D reports Title Development of the methods and softwere for determing the coordinate systems and Earth rotation parameters with the combined data analysis of the VLBI, SLR and GPS observations of celestial bodies. popup.stage_title Head Bolotina Olga.V., Registration Date 23-12-2005 Organization Main Astronomical Observatory popup.description2 Different methods for combined solution were analysed. New methods and slgorithms for parameters estimation and for combined parameters estimation are described. Combined analysis of hte SLR and GPS observations was realized (on the normal equation level). Investigations of the agreement of the different realization of the basis systems of coordinates were made.56355635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
