摘要

欧洲数据中继系统(EDRS)目前作为第一个基于激光的操作数据中继服务实施，为低地球轨道地球观测任务创建一个虚拟地面站。它基于Tesat激光通信终端(LCT)，该终端是根据DLR公司的合同开发的，用于LEO和GEO轨道上的连续通信服务。本文详细介绍了LCT的结构、发展和验证，并描述了Tesat在单光子外差探测方面的进展，该探测可以用作深空通信链路的接收器，即使在像近太阳通信链路这样的严重背景噪声水平下也能进行通信。

The European Data Relay System, high speed laser based data links

The European Data Relay System (EDRS) is currently implemented as the first operational laser based data relay service, creating a virtual ground station for low earth orbit earth observation missions. It is based on the Tesat Laser Communication Terminal (LCT), which was developed under contract from DLR for continuous communication service in LEO and GEO orbits. The paper details the structure, development and verification of the LCT, and describe the developments at Tesat for single photon heterodyne detection, that can be used as receiver for deep space communication links to enable communications even under severe background noise levels like near to sun communication links.
