PARIS (ESA PR) — The most sophisticated laser communication network ever designed has gained its second satellite.

The European Data Relay System (EDRS) was built to accelerate the flow of information from Earth-observation satellites to people on the ground.

The second satellite in the network, EDRS-C, has now passed its user commissioning review and entered into full service.

BERN, Switzerland (RUAG Space PR) — The European Data Relay System (EDRS), dubbed the “SpaceDataHighway”, uses innovative laser technology to dramatically cut the time needed for Earth observation satellites to deliver information to the ground. The second satellite to join the sister satellite already in orbit is due for launch on 6 August.

The “brain” (onboard computer) of the latest satellite, called EDRS-C, was delivered from RUAG Space to the satellite builder OHB System AG. The onboard computer controls and monitors the payload of the satellite and many other subsystems.

COLOGNE, Germany (DLR PR) — The European Data Relay Satellite System (EDRS), also known as the ‘space data highway’, is setting a new standard in real-time data transfer. The innovative laser nodes can transport data volumes of up to 1.8 gigabits per second to Earth, with minimal delay. The programme’s first communication node, EDRS-A, was launched on 29 January 2016, and is already providing relay services for data transfer from the four Sentinel satellites of the EU Copernicus Earth observation programme. The advantage is that the Earth observation satellites can deliver significantly more data to the ground faster and thus also better serve the end user (see info box). The first dedicated satellite in the series – EDRS-C – was designed, constructed and tested in Germany. It has been thoroughly tested over the past 11 months and will begin its journey to Europe’s spaceport in French Guiana in June 2019. It will be launched into a geostationary orbit on 24 July 2019 on board an Ariane 5 launch vehicle.

PARIS, 2 April 2019 (ESA PR) — The European Data Relay System (EDRS)—dubbed the “SpaceDataHighway” by its private operator, Airbus—has passed another milestone.

EDRS-A, the first satellite in what will eventually be a global constellation, has made its 20,000th successful optical link to its customer satellites since its launch in January 2016, marking a world first in laser communication in space.
