摘要

本文介绍了一种用于低轨道星座的自由空间激光通信终端。给出了光学方案，介绍了终端的工作原理及其捕获、指向和跟踪(APT)系统。根据抖动效应计算了发送信道(TX信道)的光链路预算。LEO星座的最大通信链路距离为4000公里，数据速率为10 Gbps。

Free-Space Laser Communication Terminal for LEO Constellation

This paper presents free-space laser communication (FSO lasercom) terminal for LEO constellation. The optical scheme is shown, the operation principle of the terminal and its acquisition, pointing and tracking (APT) system is presented. The calculation of the transmitting channel (TX channel) optical link budget with regard to the jitter effect is carried out. The maximal communication link distance of LEO constellation is 4000 km and the data rate is 10 Gbps.
