The mission

The European Data Relay Satellite (EDRS) system is an independent, European satellite system in the frame of the ARTES 7 program, which will settle a new standard for space based communication services.  A constellation of geostationary satellites will receive the data of Low Earth Orbit (LEO) satellites and transfer the data to the ground operations.

The dedicated EDRS-C satellite is fitted with a data relay payload with a laser communications terminal (LCT) for satellite-to-satellite links. Both have been supplied by Tesat-Spacecom. The Ka band antenna will ensure data links with ground stations in Europe at transmission speeds of up to 1.8 Gbps. Also on board the satellite is a hosted payload known as “HYLAS-3” provided by Avanti Communications.
