Lunar Laser Ranging: Consistent modelling for geodetic and further scientific applications

月球激光测距（LLR）已进行了34年以上，可以导出许多地球定向量（如章动、极移、相对论岁差），并对长期EOP序列的稳定做出了相当大的贡献。LLR的另一个优势是确定地月系统的许多参数（例如站和反射器坐标，月球轨道和重力场，潮汐加速度）沿着相对论量（例如等效原理，时变引力常数，度量参数）。在这个项目中，LLR建模将得到改进，以达到与其他空间大地测量技术相同的精度水平。这是与它们一致组合的基础，并允许更好地确定地月系统的参数和去相关。预计相对论参数的确定具有更高的精度，它们可以更好地与其他效应分离。此外，还应研究进一步的过程（例如与月球内部、相对论有关的过程）。

Lunar Laser Ranging (LLR), which is carried out for more than 34 years, allows the derivation of many Earth orientation quantities (e.g. nutation, polar-motion, relativistic precession) and contributes considerably to the stabilization of long-term EOP series. A further strength of LLR is the determination of many parameters of the Earth-Moon System (e.g. station and reflector coordinates, lunar orbit and gravity field, tidal acceleration) along with relativistic quantities (e.g. equivalence principle, time-variable gravitational constant, metric parameters). In this project LLR modeling shall bi improved to achieve the same level of accuracy as the other space geodetic techniques. This is the basis for a consistent combination with them and allows a better determination and de-correlation of the parameters of the Earth-Moon System. It is expected that the relativistic parameters are determined with higher accuracy and that they can be better separated from other effects. In addition, further processes (e.g. related to the Moon¿s interior, relativity) shall be investigated.
