Abstract

The numerical Lunar theory EPM-ERA has been developed in IAA RAS (Krasinsky 2002, Aleshkina et al.1996). In the paper (Yagudina 2008) 16320 LLR data (1970-2008) have been included for the process of improving the Moon ephemeris and obtaining some selenodynamical parameters. A new version of ERA-EPM Lunar theory was corrected by the improved model of dissipative effect of the lunar rotation by integrating the orbital and rotational motions with the retarded argument. The comparison of the improved dynamical model with 17131 LLR data from 1970 till 2010 has been made. This version has been compared with three versions of DE ephemerides
