Data-Relay Satellite Beams at Light Speed
The most sophisticated laser communication network ever on 6 August 2019, EDRS-C is in geostationary orbit some 36

System (EDRS) was built to accelerate the flow of information the communication satellite to maintain an almost constant
from Earth-observation satellites to people on the ground. The connection with Earth-observation satellites that are closer to the
second satellite in the network, EDRS-C, has now passed its user planet’s surface and circle the Earth every 90 minutes or so. The
commissioning review and entered into full service. Launched EDRS satellites use lasers to communicate with Earth-observation
satellites and beam their data back to Europe in almost real time.
Without them, there would be delays of up to 90 minutes. EDRS-C
has joined its sister satellite, EDRS-A, and can now be used by
its customers to relay information from all four Sentinel satellites
that watch over Earth, capturing day-and-night radar images
and multispectral high-resolution images of vegetation, soil and
water cover, inland waterways and coastal areas – as well as
information for emergency services. The Sentinel satellites form
part of the EU’s Copernicus program. EDRS is a new, independent
European satellite system, and is a Partnership Project between
ESA and operator Airbus as part of ESA’s efforts to federate
industry around large-scale programmes, stimulating technology
developments to achieve economic benefits. The EDRS-C
satellite platform was built by OHB System in Germany and the
laser terminals were developed by Tesat-Spacecom and the DLR
German Space Administration.
