摘要
为了满足日益增长的大数据量、高速数据传输速率的需求,NASA、ESA、JAXA等航天机构正在开启空间激光通信技术的时代。各国纷纷在GEO-LEO、LEO-LEO、LEO-地面,以及地-月等不同轨道验证了激光通信终端的在轨性能。介绍了国外开展的激光通信技术演示验证试验情况,重点介绍了以月球激光通信演示验证试验(LLCD)为代表的深空激光通信技术,以及以半导体星间链路为代表的星间激光通信技术。通过阐述国外激光通信技术的发展现状,分析了激光通信技术的未来发展趋势。期望通过该技术的研究,对我国激光通信技术的发展提供参考借鉴。
In order to meet the growing demand for big data and higher data rates,many space agencies including NASA,ESA,JAXA,are all engaged in developing laser communication technology.These space agencies are de-voting themselves in proving the in-orbit performance of laser communication terminal of GEO-LEO,LEO-LEO,and LEO-Ground.This paper illustrates the development of laser communication technology demonstration experiments carried out by such space agencies,such as deep space laser communication and inter-satellite laser communication technology,with the analysis of the future trends in this field,and with an effort to give its value for domestic laser communication technology development.
