欧洲数据中继系统（EDRS）被称为“S paceDataHighway”，使用两颗地球同步轨道卫星作为数据中继节点。该系统将在航天器和/或高空机载平台（HAP）与地面之间提供近实时的电信服务。该系统的主要优点包括：扩展的平台通信范围超过视线（BLOS），拦截所有轨道，更高的数据速率导致每天从一个GEO节点的数据中继流量容量> 50 Tb。诸如传感器数据中继高达1800 Mbps（使用激光卫星间链路），高速任务1 Mbps（闭环）和平台/传感器遥测110 Mbps的服务导致世界上第一个商业数据中继和任务服务LEO和HAP平台。
The European Data Relay System (EDRS), known as ‘S paceDataHighway’, uses two GEO satellites as data relay nodes. The system will provide a near-real-time telecommunication service between spacecraft &/or high altitude airborne platforms (HAPs) and the ground. Key benefits of the system include: Extended platform communications range Beyond Line of Sight (BLOS), Interception of all orbits, Higher data rates resulting in >50Tb per day data relay traffic capacity from just one GEO node. Services such as sensor data relay at up to 1800Mbps (using laser intersatellite links), high speed tasking at 1Mbps (close-loop) and platform/sensor telemetry at 110Mbps result in the world's first commercial Data Relay & Tasking service to LEO & HAP platforms.
