What is EUSST?


Space Surveillance & Tracking (SST)

The safety and security of the economies, societies, and citizens in Europe rely on space-based applications such as communication, navigation, and observation. Yet, due to the growing complexity of the orbital environment, space-based assets are increasingly at risk from collision with other operational spacecraft or debris. At the same time, objects may re-enter and cause damage on the ground. Mitigating these risks demands the capability to survey and track such objects and to provide this information to a variety of stakeholders.

For this purpose, a Space Surveillance and Tracking (SST) Support Framework was established by the European Union in 2014 foreseeing the creation of an SST Consortium of, initially five EU Member States (France, Germany, Italy, Spain and UK), and currently eight (also Poland, Portugal, Romania), as enlarged in 2018. “Space Surveillance and Tracking” refers to the capacity to detect, catalogue and predict the movements of space objects orbiting the Earth.

Since 2016 the SST Consortium and the European Union Satellite Centre have been working together to develop a European SST capability in a series of EU-funded projects, known as “EUSST”. The EU Member States of the SST Consortium have designated national Operational Centres for the provision of operational SST services to SST Users via the EUSST Service Provision Portal for the implementation of the SST Support Framework.
