Overview

04 ČVN. 2015 16013

The European Data Relay System (EDRS) is the most sophisticated laser communication network ever designed.

Dubbed the ‘SpaceDataHighway’, EDRS helps Earth-observing satellites to transmit large quantities of potentially life-saving data down to Europe in near-real time.

Its two geostationary satellites use optical links to gather low-orbiting satellites’ information at far higher data rates than traditional radio frequency beams.
