N2 - Installation error of optical communication terminal is introduced during the laser communications terminal installation process, and it makes the establishment of satellite-ground communication link more difficult, due to the laser only allowing for dozens of micro arcs coverage angle. In this paper, a method using in-orbit test data for laser pointing error reducing is proposed. Based on the terminal coordinate system, the cubic mirror transition coordinate system and the satellite body coordinate system, the transition matrix of the satellite body coordinate system and the terminal reference coordinate system based on the coordinate transformation is developed. Through in-orbit laser communication test, errors are obtained which is between the terminal coordinate system and the cubic mirror transition coordinate system, and between the cubic mirror transition coordinate system and the satellite body coordinate system. Finally, the terminal installation error is rectified. The proposed method is applied in in-orbit communication experiment, and shows it effectively reducing the laser antenna pointing deviation.
