There are a number of key services that will benefit from this system's infrastructure:
* Earth Observation applications in support of time-critical and/or data-intensive services; e.g., change detection, [[environmental monitoring]].
* Government and security services that need images from key European space systems such as Global Monitoring for Environment and Security.
* Emergency response and crisis intervention applications that need information and data over areas affected by natural or man-made disasters.
Line 45 ⟶ 46:
* 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 [[
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]{{Dead link|date=August 2024 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

EDRS infrastructure consists of two geostationary optical payloads and a Ka band payload, a ground system consisting of a satellite control centre, a mission and operations centre, a feeder link ground station (FLGS), and four data ground stations.
=== Space
The first EDRS payload, '''EDRS-A''', comprising a laser communication terminal and a [[Ka band|K<sub>a</sub> band]] inter-satellite link, was placed on-board [[Eutelsat]] commercial telecommunication satellite, called Eutelsat 9B (COSPAR 2016-005A). The satellite was launched in January 2016 by a [[Proton-M]] rocket and will be positioned at 9°E.<ref name="Eutelsat9Blaunched">{{cite web|title=Lift-off for Europe's space laser network|url=https://www.bbc.com/news/science-environment-35446894|website=bbc.com|date=30 January 2016|access-date=30 January 2016}}</ref><ref>[http://www.satellitetoday.com/launch/2014/01/16/ils-to-launch-eutelsat-9b-satellite-in-2015/ ILS to Launch Eutelsat 9B Satellite in 2015]</ref>
A second EDRS payload was launched aboard a dedicated spacecraft.

The EDRS A and C form the initial core [[space infrastructure]] that provides direct coverage for LEO satellites over Europe, the Middle East, Africa, the Americas, Asia, and the Poles.
=== Ground
The [[ground segment]] of EDRS includes three [[ground station|ground receiving station]]s located at Weilheim, Germany, Redu, Belgium and Harwell, UK. The prime [[Mission Operations Centre]] is in Ottobrunn, Germany, while a backup centre
The EDRS-A payload as well as the EDRS-C satellite are operated by the German Space Operations Center (GSOC) of the [[German Aerospace Center]] in Oberpfaffenhofen near Munich, Germany.
