摘要

到2025年，欧洲航天局计划实施一些目前正在研究或计划中的科学任务，这些任务将把卫星放在月球、地球-太阳拉格朗日点、火星和木星周围的轨道上。初步研究正在进行中，以确定为专用科学数据通道提供光通信系统的可行性，目的是在类似质量、功率和尺寸限制的情况下，将目前的主力军射频链路带宽提高一个数量级。目标是在距离1 AU的地方提供100 Mbps的信道带宽，全球通信链路可用性达到95%。

Deep space science downlinks via optical communication

By the year 2025 the European Space Agency plans to be operating a number of currently studied or planned scientific missions which will place satellites in orbits around the Moon, the Earth-Sun Lagrange points, and Mars and Jupiter. Initial studies are underway to determine the feasibility of providing optical communications systems for dedicated science data channels with the objective to improve upon the present workhorse radio frequency link bandwidths by an order of magnitude within similar mass, power, and size limitations. The target is to provide 100 Mbps channel bandwidth from a distance of 1 AU with a global communication link availability of > 95%.
