IRIS2 is the new European Union secure satellite constellation. This project is the European Union’s answer to the pressing challenges of tomorrow to provide secure connectivity services and enhanced communication capacities to the EU and its Member States. In addition, as well as to governmental users, private companies and European citizens while benefiting from ensuring high-speed internet broadband to cope with connectivity dead zones.

SES - together with other consortium partners and core members, was selected by the European Commission to build and to operate the IRIS2 multi-orbit satellite constellation.

The IRIS2 team enters next project phases, we seek and there is a strong need of support for all the activities around service provisioning and products that the system can offer in the future.
