EU SST Factsheet

EU Space Surveillance and Tracking (EU SST) is a key capability that helps to protect space infrastructure and services from in-orbit collisions between space objects and other disruptions. It thereby safeguards European economies, societies and citizens who increasingly rely on space-based services such as navigation or Earth observation, and so contributes to the resilience of European space assets and to a higher level of EU strategic autonomy. 

Integrated in 2021 as a full-fledged subcomponent of the EU Space Programme, EU SST is fully operational, with its own network of sensors from EU Member States, a database connecting national Operations Centres, and services provided to users through the EU SST Front Desk at EUSPA. It is also security relevant: its internal data policy protects sensitive information and the security interests of EU SST partners, and gives guidelines on handling SST data.
