Creotech Instruments S.A. has joined the signatories of a letter of intent launching an initiative to create a hybrid satellite constellation in the Three Seas region. The document was signed on April 29, 2026, during the Three Seas Summit and Business Forum in Dubrovnik.
The project aims to build a regional satellite data-sharing system on a scale not previously seen in Central and Eastern Europe. The joint initiative brings together companies from Three Seas countries, including Croatia, Czechia, Greece, Poland, Slovakia and Slovenia. Its goal is to significantly strengthen Earth observation capabilities by sharing satellite resources and developing interoperable ground infrastructure.
Creotech’s involvement forms part of broader efforts to reinforce the European space sector and build independent regional capabilities in acquiring and using satellite data. Such data are increasingly important for security, the economy and crisis management.
The signing ceremony was attended by Ivan Anušić, Deputy Prime Minister and Minister of Defence of Croatia; Harry Theoharis, Deputy Minister of Foreign Affairs of Greece; Marcin Przydacz, Secretary of State and Head of the International Policy Bureau at the Chancellery of the President of Poland; and Rastislav Chovanec, State Secretary of Slovakia.
“Participation in this initiative is an important step towards building a strong regional space ecosystem. Through cooperation among Three Seas countries, it will be possible to significantly increase the efficiency of satellite data use and develop advanced space technologies in Central and Eastern Europe,” said Grzegorz Brona, CEO of Creotech Instruments S.A.
He added that the hybrid constellation initiative shows that coordinated action and shared resources can create a scale effect that would be difficult for individual countries to achieve on their own. According to Brona, the open nature of the project also creates room for further companies and countries to join at later stages.
“This is not only a matter of technology, but also of security, infrastructure resilience and better responses to challenges such as climate change and geopolitical instability. For Creotech Instruments S.A., it is also an opportunity to further strengthen its capabilities in satellite systems and actively participate in building Europe’s Earth observation capacity,” Brona said.
The initiative envisages a new model of cooperation between countries in the region in the use of Earth observation data. The project is based on the assumption that satellites owned by individual countries could also perform imaging tasks for other member states, substantially increasing data availability for each participant.
In the first stage, cooperation will cover data exchange and mutual commissioning of satellite imagery. The next step will be the integration of ground infrastructure. Receiving stations in individual countries would be able to receive data from partner satellites and serve as mutual backups, increasing the resilience of the entire system.
The fact that most Three Seas countries are members of the European Space Agency is expected to facilitate interoperability between satellites from different countries.
The letter of intent is non-binding and sets the direction for further cooperation between space-sector companies from Croatia, Czechia, Greece, Poland, Slovakia and Slovenia. The signatories in Dubrovnik act as the initiators of the project, which is expected to be expanded to include new partners at later stages.
The participating countries were represented by selected space-sector companies and organisations, including Creotech Instruments, CloudFerro and Eycore from Poland; VZLU Aerospace, Groundcom and Czech Space Alliance from Czechia; the Hellenic Association of Space Industry and Geosystems Hellas from Greece; SPACE-SI from Slovenia; Protostar Labs from Croatia; and Sab CTRL Space and Touch4IT from Slovakia.
The significance of the project extends beyond the space sector. Satellite data now play a key role in areas such as security, critical infrastructure protection, crisis management and climate change monitoring. A joint Three Seas constellation could become one of the foundations for strengthening the region’s resilience in a changing geopolitical environment.
The signing of the document in Dubrovnik marks a first but important step towards creating a regional satellite system that could strengthen Central and Eastern Europe both technologically and strategically.
