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 that risk involves the capability to survey and track such objects, and to provide this information to a variety of stakeholders.
