SST & STM system architecture and evolutions. Horizon Europe TOP2

SST & STM system architecture and evolutionsThe specific objectives of the HE_EUSST_MS_TOP2 action have been defined considering the specific objectives defined in the Work Programme:• Foster European cooperation in the SST domain and improve the EUSST performance towards larger autonomy.• Highlight and propose solutions to fill the gaps in the current EUSST architecture.• Pave the way on which the EUSST system has to evolve towards a higher level of performance (e.g. accuracy; number / size of catalogued objects...), quality of service (e.g. timeliness of information...) and autonomy.• Demonstrate the complementarity, coherence and added-value of each element of EUSST system towards a more autonomous, interoperable SST system.Explore and look for higher levels of cooperation with other SST systems such as the US SSA system which is of paramount importance to develop long-term cooperation.• Raise the main issues and propose relevant answers to questions posed by all those developments in various technical and operational domains based on the outcome of the previous STM coordination and support actions developed under H2020.• Propose adaptation to the new changes, and solutions for their possible integration into the existing standards, practices and technological means.The state of the art on the topic can be summarized as the current activities carried out in project 2_3SST2018-20 and the current grants under HE.
