- Abstract
Lunar Laser Ranging (LLR) data of more than 20 years have been used to accurately determine parameters of the Earth-Moon system (e.g., the mass of the system, the lunar tidal acceleration etc.), the station-reflector geometry, and other physical parameters like the solar quadrupole moment J2⊙. In addition to these, parameters suitable for testing metric theories of gravity in the first post-Newtonian approximation have been determined with great accuracy. These are the PPN (parameterized post-Newtonian) parameters γ and β, the Nordtvedt parameter ç, the geodetic precession of the lunar orbit ΩGP, as well as a possible time variation of the gravitational constant G.
