Abstract:

In the article some theoretical and practical aspects of common estimation of stations coordinates, Earth rotation parameters and gravity field coefficients by combining of SLR data from LAGEOS and LEO satellites are presented. Correlation between parameters and errors for different configurations of orbital group are discussed. Two methods of combination have been analyzed. The first method is a combination on observation level which means that observations from different satellites are combined in the common system of equations observation. The second method is a combination on normal equations level, it enables to combine results from different measurement techniques or from sequential time intervals.
