The EU Space Surveillance and Tracking (EU SST) Partnership has officially grown to 19 EU Member States, marking a significant expansion of the EU SST capabilities. Following an Implementing Decision adopted by the European Commission, the signature of a new SST Partnership Agreement was recently finalised and entered into force on 12 April 2026, completing the addition of four new Member States to the Partnership.
The Partnership’s Member States, represented by their Constituting National Entities, will continue joining forces and networking their national assets to improve EU SST’s performance and autonomy in the Space Situational Awareness (SSA) domain and contribute to ensuring space safety and sustainability. The new Partnership, in cooperation with EUSPA acting as the EU SST Front Desk, will build on EU SST’s successful track record of service provision, with more than 600 satellites currently safeguarded from the risk of collision and more than 400 organisations benefitting from space safety services.
The four new Member States of the EU SST Partnership are:
- Belgium – Minister of Defence of the Kingdom of Belgium (BE MoD)
- Bulgaria – Ministry of Innovation and Growth of the Republic of Bulgaria (MIG)
- Lithuania – Innovation Agency Lithuania (IAL)
- Luxembourg – Ministry of Economy, SME, Energy and Tourism of Luxembourg (MECO)
The new members have teamed up with the 15 Member States that are part of EU SST since the Partnership’s creation in 2022:
- Austria – Austrian Research Promotion Agency (FFG)
- Czech Republic – Ministry of Industry and Trade (MPO)
- Denmark – Danish Ministry of Defence Acquisition and Logistics Organisation (DALO)
- Finland – Finnish Meteorological Institute (FMI)
- France – Centre national d'études spatiales (CNES)
- Germany – German Space Agency (DLR)
- Greece – National Observatory of Athens (NOA)
- Italy – Agenzia Spaziale Italiana (ASI)
- Latvia – Ministry of Education and Science of the Republic of Latvia (IZM)
- the Netherlands – Ministry of Economic Affairs (EZ)
- Poland – Polish Space Agency (POLSA)
- Portugal – Ministry of National Defence (PT MoD)
- Romania – Romanian Space Agency (ROSA)
- Spain – Agencia Espacial Española (AEE)
- Sweden – Swedish National Space Agency (SNSA)
The main objectives of the Partnership are to:
- deliver operational, public SST services to users through a service provision model based on the best available expertise in Europe;
- achieve a higher level of European Union strategic autonomy in space surveillance and tracking;
- foster innovation and competitiveness of the European industry and start-ups ecosystem in the SSA domain;
- exploit synergies between civil and defence, acknowledging the security dimension and dual nature of SSA, and
- engage with international partners and promote global coordination between SSA systems around the world.
“On behalf of the EU SST Partnership, I am delighted to welcome Belgium, Bulgaria, Lithuania, and Luxembourg as our newest Member States. This marks a significant step forward in our mission to provide “SSA made in Europe” and to reinforce our strategic autonomy, which begins with strategic awareness. Together, we will continue to build a more resilient and collaborative space surveillance network for Europe and beyond”, stated Pascal Faucher, Chair of EU SST.
An amendment to the Implementing Arrangement between the EU SST Partnership and EUSPA, which entered into force on 14 April 2026, has also been signed.
As next steps, the Partnership will sign new EU-funded grants that will allow EU SST to continue its activities until 2028, and EU SST will mark soon 10 years of service provision.
As part of the Space Situational Awareness component of the EU Space Programme, EU SST remains the key operational capability for the EU's future approach to Space Traffic Management, continuously working on improving its sensors network and data processing capabilities while developing new services.
