太字节红外传输（TBIRD）计划将建立从低地球轨道上的6U纳米卫星到地面站的光通信链路，突发速率高达200 Gbps。该系统能够在存在大气衰落的情况下从有效载荷上的2TB存储缓冲器向地面终端可靠地传送数据。概述了TBIRD的通信体系结构，以及在航天器集成之前对3U激光通信有效载荷进行通信性能测试的结果。发射计划于2022年年中。
The Terabyte Infrared Delivery (TBIRD) program will establish an optical communication link from a 6U nanosatellite in low-Earth orbit to a ground station at burst rates up to 200 Gbps. The system is capable of reliable data delivery from a 2-TB storage buffer on the payload to a ground terminal in the presence of atmospheric fading. An overview of the communication architecture for TBIRD is provided as well as results from communications performance testing of the 3U lasercom payload prior to spacecraft integration. Launch is scheduled for mid-year 2022.
