Mission Details

EDRS-C (Hylas 3)

The European Data Relay System (EDRS) system is a European constellation of state-of-the-art GEO satellites that 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 makes on-demand data available to, for example, rescue workers who want near-real-time satellite data of a crisis region.
