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.
