The most refined laser communication community ever designed has gained its second satellite tv for pc.

The European Information Relay System (EDRS) was constructed to speed up the circulate of knowledge from Earth-observation satellites to individuals on the bottom.

The second satellite tv for pc within the community, EDRS-C, has now handed its consumer commissioning assessment and entered into full service.

Launched on August 6, 2019, EDRS-C is in geostationary orbit some 36,000 kilometers above Earth.

This geostationary place permits the communication satellite tv for pc to keep up an virtually fixed reference to Earth-observation satellites which are nearer to the planet’s floor and circle the Earth each 90 minutes or so.

The EDRS satellites use lasers to speak with Earth-observation satellites and beam their information again to Europe in virtually actual time. With out them, there can be delays of as much as 90 minutes.

EDRS-C has joined its sister satellite tv for pc, EDRS-A, and may now be utilized by its prospects to relay info from all 4 Sentinel satellites that watch over Earth, capturing day-and-night radar pictures and multispectral high-resolution pictures of vegetation, soil and water cowl, inland waterways and coastal areas – in addition to info for emergency providers.

The Sentinel satellites type a part of the EU’s Copernicus program.

EDRS is a brand new, unbiased European satellite tv for pc system, and is a Partnership Mission between ESA and operator Airbus as a part of ESA’s efforts to federate trade round large-scale applications, stimulating know-how developments to attain financial advantages.

The EDRS-C satellite tv for pc platform was constructed by OHB System in Germany and the laser terminals had been developed by Tesat-Spacecom and the DLR German House Administration.
