在TELEO演示的框架内，由空中客车公司领导的欧洲财团正在图卢兹开发一种空间光学仪器。这一激光通信终端将于2023年期间置于地球同步轨道上。我们的飞行实验室将展示新技术（如指向机制，光学放大器，红外相机）和相关概念，如指向采集和跟踪（PAT）策略。光学仪器由一个26厘米的望远镜组成，望远镜由一个机械装置操纵。由于采用了低变形热机械概念，整个结构设计确保了光学器件的高性能。一个紧凑的焦平面组件是容纳在这个望远镜。它用于以极高的抑制效率管理高光功率Tx以及接收到的信标和Rx波束。专用电子设备还包括用于高度稳定的热调节、模式和PAT算法管理、功率分配、机械驱动器、探测器采集、激光源和光学放大器的终端。在卫星上进行集成和最后环境测试之前，正在制造电信设备的所有构件，并测量其性能。可以在补充内容页面上访问其他演示内容。
In the framework of the TELEO demonstration, a space optical instrument is being developed by a European consortium led by Airbus at Toulouse. This laser communications terminal will be placed on GEO orbit during the year 2023. Our flight laboratory will demonstrate new technologies (such as pointing mechanisms, optical amplifier, Infra-Red camera) and the associated concepts such as Pointing Acquisition and Tracking (PAT) strategy. The optical instrument is composed of a 26 cm telescope steered by a mechanism. The whole structure design ensures high performance of the optics thanks to a low distortion thermo-mechanical concept. A compact Focal Plane Assembly is accommodated under this telescope. It is used to manage with tremendously high rejection efficiency the high optical power Tx and the received beacon and Rx beams. Dedicated electronics also compose the terminal for highly stable thermal regulation, modes and PAT algorithms management, power distribution, mechanisms drivers, detector acquisition, laser sources and optical amplifiers. All the building blocks of the TELEO instrument are now being manufactured and their performances are being measured, before integration and final environment tests on the satellite.
