Aerospace giant, Airbus Defence and Space is also working as a partner and service operator to this program. The first node, called EDRS-A, will begin relaying information this summer from its first customers: the ESA/European Commission Copernicus Sentinel-1 and -2 satellites.

EDRS is the most ambitious telecom program of ESA, which is creating the means for an entirely new market in commercial satellite communications. Dubbed as 'SpaceDataHighway', EDRS will uniquely provide near-realtime Big Data relay services using cutting-edge laser technology. It will dramatically improve access to time-critical data, aiding disaster response by emergency services and maritime surveillance, for example.

From that point on, ESA and Airbus will use the first and future EDRS nodes to increase the time low-orbiting satellites, the International Space Station and unmanned aircraft can send data to Earth from intermittent to near-continuous, opening up a wealth of new possibilities.

Once fully deployed, EDRS will relay up to 50 terabytes of data from space to Earth every day. It will eliminate the downlink delay currently prohibiting immediate access to satellite information and phase out Europe's reliance on foreign ground stations.

EDRS-A will be launched as a hosted payload on the Eutelsat-9B satellite on 29 January at 22.20 GMT (23:20 CET, 04:20 30 January local time) on a Proton rocket, with satellite separation around 9 hours later. In-orbit tests will begin on the EDRS laser payload three weeks later. The payloads were built by Airbus subsidiary TESAT-Spacecom and funded by the DLR German Aerospace Center Space Administration.
