For the first satellite-ground laser communication links of China, beam pointing deviations are existed due to the coordinate system pointing errors of terminal adjustment and installation. The pointing angle deviation is 8 mrad and the acquisition time is larger than 40 s, which have a serious effect on the acquisition performance. Based on that, the transformation matrix between the satellite coordinate system and the terminal coordinate system is given based on the cubic mirror correction system. At last the correction angles are obtained and the correction of pointing brought by ground station is made. The in-orbit test results of haiyang-2 (HY-2) show that the pointing angle deviation between terminal and ground situation decreases from 8 mrad to 0.8 mrad, the scan area is decreased and the acquisition time of optical communication terminal decreases from 40 s to less than 5 s. The in-orbit experimental results show that this method can be accurate to compensate on the pointing deviations than that of other countries, revising the results to meet the requirements of the laser communications link established.
