European Data Relay System
The European Data Relay System (EDRS) system is a planned European constellation of state of the art GEO satellites that will relay information and data between satellites, spacecraft, UAVs, and ground stations. The designers intend the system to provide almost full-time communication, even with satellites in low Earth orbit that often have reduced visibility from ground stations. It will make on-demand data available to, for example, rescue workers who want near-real-time satellite data of a crisis region.
