We present estimated values for the global elastic parameters (h2, l2) derived from the analysis of Satellite Laser Ranging (SLR) data. We analyse SLR data for LAGEOS 1 and LAGEOS 2 and for two low satellites, STARLETTE and STELLA, collected over a period of 2.5 years, from January 1 2005 to July 1 2007, from 18 globally distributed ground stations. The adjusted final values (h2, l2) for all satellites are compared. A major discrepancy between the two solutions was only found for the Shida number l2.
