Abstract
The analysis of LLR data 1970-2008 was carried out applying different numerical theories DE403, DE405, DE421 and theory EPM-ERA developed in IAA RAS. New 453 LLR observations, obtained at the laser station of new generation Apache during 2006-2008 have been included in the process. The partials calculated for by EPM-ERA were made use also of DE ephemeredes. It is shown that slightly more poor fitting by EPM-ERA (rms is 7.2 cm while 5.6 cm for DE) is caused by approximate taking into account of dissipative effects of the Moon. On the other hand, the high precision of DE ephemerides distributed as Cheyshev's polynomials is not available for users. The residuals these theories are characterised by the error about 22 cm due to impossibility to feed back the estimated corrections to their parameters (except coordinates of the stations and reflectors)
