Elements of the Network:

DHRs and CollGS

The Collaborative GS and DHR Network has been designed to increase the number of data access points and overall re-dissemination capacity of Sentinel Data, in order to reduce the load on ESA’s core providing redundancy for unavailability, while reducing the load on standard access from the Core Ground Segment managed by ESA.

The participants to this network are:
• Collaborative Ground Segment;
• Copernicus Data Hub Relays.


Who are the

Collaborative users?


The Collaborative Ground Segment consists of National entities retrieving and disseminating data to their local communities for EO data exploitation.


Data Hub Relays


The Copernicus Data Hub Relays act as an additional distributed set of data access points transferring data within the network and to national CollGS.
