The Lense-Thirring effect is currently being measured by means of acombination of the orbital residuals of the nodes of LAGEOS and LAGEOS II andthe perigee of LAGEOS II. The total error is of the order of 20%. The mostinsidious systematic error is due to the mismodelled even zonal harmonics ofthe geopotential and amounts to 12.9%, according to EGM96 model. The role andthe importance of the LAGEOS--LAGEOS II Lense--Thirring experiment isinvestigated. Using other suitable combinations with orbital elements of theother existing laser-ranged satellites does not yield significativeimprovements except for one combination including the nodes of LAGEOS, LAGEOSII and Ajisai and the perigee of LAGEOS II. The related systematic error due tothe mismodelled even zonal part of the geopotential reduces to almost 10.7%.Comment: LaTeX2e, 1 table, no figures, 8 page

Is it possible to improve the present LAGEOS LAGEOS II Lense Thirring experiment?
