Based on the J 2 orbit prediction model, lunar satellites with various inclinations and orbital heights have been designed. Then, by comparing the simulation results of the J2
orbit prediction model with the direct integration RKF7 (8) simulation results,pointing accuracy of lunar-ground laser communication is studied. The laser communication terminal is installed on the -Y plane satellite deck in our simulation. To a certain extent,the results show that the J2
orbit prediction model can meet the requirements of lunar polar remote sensing satellites for lunar-ground laser communication. When the orbital height is 1 000 km and 2 000 km,the azimuth deviation of 10 min does not exceed 40 μrad,and the pitch angle deviation is only about 7 μrad. The orbit prediction model can satisfy the lunar-ground laser communication pointing requirements.
