Second flight

EDRS-C is the second satellite to use the SmallGEO platform.

It is the second node to the European Data Relay System, a unique public–private partnership between ESA and Airbus.

The system – dubbed the SpaceDataHighway by industry – provides data relay between low orbiting satellites and the EDRS nodes over optical links, with the information sent down to Europe in near-real time.

EDRS-C is the first dedicated EDRS satellite, and will double the system's capacity in orbit.
