Facts & Figures
What is SST?
The EU Space Surveillance and Tracking (EU SST) protects satellites and space infrastructure from collision risks, monitors in-orbit fragmentations, and uncontrolled re-entries, protecting EU missions like Galileo, EGNOS, Copernicus and GOVSATCOM, as well as national and commercial spacecraft. As part of the EU Space Programme’s Space Situational Awareness component, it safeguards the European economies, societies and citizens who rely on space-based services.
The EU SST Front Desk, managed by EUSPA, is the central access point for SST services and information, providing satellite operators with timely warnings and expert guidance to prevent collisions and protect space assets.
Launch
EU SST was initially established in 2014, and since 2021 it has been part of the EU Space Programme.
Implementation
The EU SST Partnership, together with EUSPA acting as the EU SST Front Desk, work together to develop a European SST capability.
Purpose
To contribute to the safety and sustainability of space operations by providing a set of Space Surveillance and Tracking services.
