月球激光测距（LLR, Lunar Laser Ranging）已经发展了50多年，极大推动了地月科学、月球空间基准以及引力物理的发展。为了充分利用LLR的宝贵数据，本文依据目前广泛应用的IERS2010规范（International Earth Rotation Service Convention 2010），对固体潮、海潮、大气延迟和广义相对论效应等进行建模，并建立了月球激光测距观测数据处理模型。利用这一模型，检核了ILRS（International Lunar Ranging Service）提供的所有LLR观测数据。本文应用该模型生成了月球角反射器预报文件CPF（Consolidated Prediction Fo rmat），支持了云南天文台LLR观测独立自主实施。同时，利用模型对比了INPOP19a,D E430（Developed Ephemeris 430）,EPM2017（Ephemeris of Planets and the Moon）作为观测模型的输入时检核LLR标准点数据，结果显示出法国的历表INPOP19a模型与实测数据更为接近。

LLR (Lunar Laser Ranging) has been developed for 50 years, which greatly promotes the development of Earth Moon science, lunar spatial reference and gravitational physics. In order to make full use of the valuable data of LLR, according to the widely used IERS2010(International Earth Rotation Service Convention 2010), the earth tide, ocean tide, atmospheric delay and general relativity effect and other high precision models are modeled, and the lunar laser ranging observation data processing models is established. Using this model, all the LLR observation data provided by ILRS (International Laser Ranging Service) are processed. This paper uses the model to generate the lunar corner reflector forecast CPF file, which is of major significance for the independence of Chinese independent LLR activities. At the same time, compared with INPOP19a, DE430, EPM2017 as the input of the observation model when processing LLR normal point data, the results show that the French ephemeris INPOP19a simulation results are closer to the measured data.
