自欧洲空间局（欧空局）的地球静止数据中继卫星ARTEMIS于2003年2月开始运行以来，欧空局和加那利群岛天体物理研究所在ARTEMIS与安装在西班牙加那利群岛天体物理研究所泰德天文台的光学地面站之间进行了例行的双向光学链路试验。这些实验旨在静态和动态地表征不同大气湍流条件下光下行链路和上行链路的性能，同时开发和测试预测链路性能的适当理论模型。概述了OGS和IAC泰德天文台顶部的附加设施，以及不同的实验配置，包括不同数量的发射子孔径和发散的上行链路的传播和通信的统计结果的总结。关键参数，如闪烁和衰落和浪涌统计，与理论预测和分析的远场图案。还介绍了OGS与欧空局卫星SMART-1之间的深空上行链路实验结果。最后对欧空局的自由空间光通信计划进行了总结，包括不同卫星上的光学有效载荷。
Since the European Space Agency (ESA) geostationary data-relay satellite ARTEMIS started its operation in February 2003, ESA and the Instituto de Astrofisica de Canarias (IAC) have carried out routinely bidirectional optical link experiments between ARTEMIS and the Optical Ground Station (OGS), installed in the Teide Observatory of the IAC in the Canary Islands, Spain. The experiments aimed at characterizing statically and dynamically the performance of the optical downlinks and uplinks in different atmospheric turbulence conditions, together with the development and testing of appropriate theoretical models to predict the link performance. An overview of the OGS and additional facilities on top the IAC Teide Observatory is given, as well as a summary of the statistical results on propagation and communication for different experimental configurations, including different number of transmitting subapertures and divergence in the uplink. Key parameters, like scintillation and fade and surge statistics, are correlated with theoretical predictions and an analysis of the far field pattern is included. The results of the deep space uplink experiments between the OGS and ESA satellite SMART-1 are also presented. Finally ESA free space optical communication programs are summarised, including optical payloads on board different satellites.
