New & improved EUSST Missions and Services. Horizon Europe TOP1

This Horizon Europe grant is to be understood within a wider context on EUSST, where other grants are being executed simultaneously with the common objective of improving the EU autonomy on Space Surveillance and Tracking.In particular, this TOP focuses on:- Keep the knowledge and capabilities of Europe on the Space Surveillance and Tracking domain at the leading edge.- Adapt, improve and evolve the current EUSST initial services (Collision Avoidance; Fragmentation; Re-entry) portfolio to future user needs and space environment.- Improve the overall performance of the EUSST services and ensure, in the long-term, a high level of performance and appropriate autonomy at Union level.- Identify and define new missions and services (e.g. debris mitigation; debris remediation). - Explore the implementation of new services, in complement of the three existing ones. - Support the pre-developments and end-to-end early demonstration of new SST services.The starting point of these activities is the output of 2-3SST2018-20, which constitutes the state of the art on SST matters.
