The laser diode coupling unit is an important part of the intersatellite optical communication system. 激光耦合系统是星间光通信系统的重要组成部分。
In this paper, it elaborates obvious advantages as compared with applications of laser intersatellite links between relay satellites and in satellite constellation of middle and low earth orbit for global satellite communication networks. 阐述在中低轨道卫星星座全球通讯网络中应用的激光星间链路与在中继星间应用的激光星间链路相比,所具有的明显的优势。
Because of the narrow laser beam and the long distance between the satellites, the effect of the setting precision of the intersatellite optical communication terminal to the PAT ability is increased. 由于激光光场光束窄,星间距离大,使得卫星光通信终端安装精度对PAT性能的影响增大。
