SpaceDataHighway Demonstrates its Unique Timeliness Capability During Live Event
(Source: Airbus; issued July 22, 2019)
A Sentinel satellite is taking an image to identify dark vessels and potential oil spills and making this time-critical information available in almost real time to users thanks to the European Data Relay System (EDRS). This highly valuable capability has been successfully showcased during a live demonstration held at the headquarters of the European External Action Service in Brussels on 10 July.

“This event marks the first official live demonstration of this globally unique data relay capability based on cutting-edge laser technology able to send data over distances of 40.000km at 1.8Gbps. Connected via a live stream with the EU delegation in Tokyo, this event also allowed invited Japanese industries and institutional representatives to follow our live link session during a parallel event organized by Airbus and its business partner JSAT.” explained Mathias Schneidereit, leading the EDRS market development activities at Airbus.

Dubbed the “SpaceDataHighway” service, the EDRS infrastructure enables Earth-observation satellites to deliver their information to users on the ground in near real-time, accelerating responses to emergency situations and spurring the development of new services and products.

The system works by using highly precise lasers to speed up the data relay of imagery from Low Earth orbiting satellites. Without EDRS, these satellites can only dump their information when they are in direct line-of-sight with a ground station, which happens on average only every 90 minutes. With EDRS, they send their data through space via a laser link to telecommunication satellites in a higher, geostationary orbit that have a constant view of a ground station.

Delegates at the meeting watched staff from the European Maritime Safety Agency (EMSA) analyse images of ships off the coast of French Guiana that were captured just seconds earlier by an Earth-observation satellite called Sentinel-1B as it orbited the planet.

The team was able to pinpoint more than 40 individual ships on a 60,000 square kilometre patch of the Atlantic Ocean that was twice the size of Belgium. They even checked the ships’ wakes for any evidence of oil spills – and found none on this occasion. The whole process took approximately 10 minutes until the image was shown live in Brussels and Tokyo.

EDRS is a public–private partnership between ESA and Airbus, with significant investment by the German Space Administration DLR. Besides the first long term customer Copernicus, the SpaceDataHighway data relay services will be used by Pleiades NEO from 2020 onwards.

Evert Dudok, Executive Vice-President at Airbus, said: “The SpaceDataHighway and the EDRS service is a unique European capability. It is truly pioneering and as we saw today, it puts earth observation at our fingertips.”

Magali Vaissiere, Director of Telecommunications and Integrated Applications at ESA, said: “EDRS has a wealth of applications. To stay ahead of the international competition, we have to make sure that EDRS meets the real needs of users and we have to keep on investing in the infrastructure itself to make it global. It will become a worldwide commercial success.”
