About si-Cluster

Who we are

The Hellenic Space Technologies and Applications Cluster (si-Cluster) is an innovation cluster operating in the field of Space Technologies and Applications in Greece. It was established in 2009 as a joint initiative of Corallia, a Unit of the Research Centre Athena, and the Hellenic Association of Space Industries (HASI). It is an industry-led and user-driven innovation cluster active in the field of Space Technologies and Applications in Greece. It brings together more than 70 Greek businesses, academic and research centers and other private and public sector organisations and the civil society. The si-Cluster underpins industrial and scientific excellence in specific fields of space technologies and applications, respecting the diverse missions, roles and responsibilities of industrial members, the academic and research community, the public administration and end users. It operates within an active quadruple helix for the benefit of the whole space ecosystem and other important sectors of the economy, such us Agriculture, Transport, Environment, Security, Defence, Telecoms, etc. The si-Cluster members have been recognized internationally for the innovative technologies and solutions they develop and offer. They address international markets and have achieved significant successes, “opening up” another sector of activity for the Greek economy. The si-Cluster is considered the leading hi-tech “project” of the country. Its cooperative structure and its successful operating model guarantee success and synergies in an extremely demanding technological sector. The important infrastructures, the international network of collaborations and the close links with actors of the wider innovation ecosystem have created a strong framework for the development of competitive advantages.

Our vision

si-Cluster’s vision is to sustain a world class cluster on Space Technologies and Applications.

Our mission

si-Cluster’s mission is to place Greece on the global map of this highly developing and competitive market, based on the country’s rich scientific potential and build capacities to attract high-impact research, innovation and commercial activities that will benefit the society.
