* Weather satellite services that require the fast delivery of large quantities of data around the world.
The system has been developed as part of the [[ARTES]] 7 programme and is intended to be an independent, European satellite system that reduces time delays in the transmission of large quantities of data. The programme is similar to the American [[Tracking and Data Relay Satellite System]] that was set up to support the Space Shuttle—but EDRS is using a new generation [[Laser Communication Terminal]] (LCT) which carries data at a much larger [[bit rate]]: the laser terminal transmits 1.8
Such a terminal was successfully tested in 2007/8 during in-orbit verification between the German radar satellite [[TerraSAR-X]] and the American [[Near Field Infrared Experiment|NFIRE]] satellite, both in LEO, when it achieved 5.5 gigabits per second.<ref name=TerraSAR-X-NFIRE-2009>[https://www.dlr.de/content/en/downloads/news-archive/2009/20090615_two-years-of-successful-operation-for-germany-s-terrasar-x-the-earth-observation-satellite_17874.pdf ''Two years of successful operation for Germany's TerraSAR-X, the Earth observation satellite'' DLR June 2009]</ref>

EDRS is being implemented as a Public Private Partnership (PPP) between the [[European Space Agency]] (ESA) and [[Airbus Defence & Space]] (ADS, former Astrium).<ref name="ESA and Astrium sign PPP">[http://www.esa.int/esaTE/SEMQD49U7TG_index_0.html EDRS: An independent data-relay system for Europe becoming reality]</ref> ESA funds the infrastructure development and is the anchor customer through the Sentinel satellite missions.
