Abstract
In this paper we present results for the global elastic parameters: Love number h2 and Shida number l2 derived from the analysis of Satellite Laser Ranging (SLR) data. SLR data for the two low satellites STELLA (H=800km) and STARLETTE (H=810km) observed during 2.5years from January 3, 2005 until July 1, 2007 with 18 globally distributed ground stations were analyzed. The analysis was done separately for the two satellites. We do a sequential analysis and study the stability and convergence of the estimates as a function of length of the data set used.The final adjusted values for h2 equal to 0.6163±0.0037 and 0.6048±0.0025, and those for l2 equal to 0.0176±0.0017 and 0.1151±0.0010 for STELLA and STARLETTE tracking data are compared to estimates we previously published based on data for two high satellites LAGEOS1 (H=5860km) and LAGEOS2 (H=5620km) (Rutkowska and Jagoda, 2010a). A major discrepancy between the two solutions was found for the Shida number l2.
