月球激光测距（LLR）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数据，依据目前广泛应用的国际地球自转服务2010（IERS 2010）规范对固体潮、海潮、大气延迟和广义相对论效应进行建模，并建立了LLR观测模型。利用该模型检核了国际激光测距服务（ILRS）提供的所有LLR观测数据，生成的月球角反射器预报文件CPF（Consolidated prediction format）支持云南天文台LLR的独立观测。将INPOP19a、DE430、EPM2017历表作为观测模型输入并检核LLR标准点数据，结果表明，相比其他历表，INPOP19a历表与实测数据更接近。 

Lunar laser ranging (LLR) has promoted the development of earth-moon science, lunar spatial reference, and gravitational physics. To fully use the LLR data according to the widely used International Earth Rotation Service 2010 (IERS 2010) specification, the solid tide, ocean tide, atmospheric delay, and general relativity effects are modeled, and the LLR observation model is established in this paper. All LLR observation data provided by the International Laser Ranging Service are checked with the model, and the generated Lunar Corner Reflector Prediction File in CPF (Consolidated prediction format) supports Yunnan Observatory’s independent LLR observations. The INPOP19a, DE430, and EPM2017 almanacs are input as observation models to check the LLR standard point data. The results show that the INPOP19a almanac is closest to the measured data than other almanacs.
