LEONSEGS-Large Earth Observation new space ecosystem ground segment

LEONSEGS is a federated multi-mission Earth Observation Ground Segment Service Platform that connects EO data providers, New Space satellite operators and data platforms through harmonised interfaces managed by a central automated service. The poster outlines how LEONSEGS follows a Ground Segment as a Service (GSaaS) approach to integrate multiple missions, coordinate satellite tasking and combine heterogeneous datasets into tailored EO products. It highlights benefits such as unified access to EO data and services, improved timeliness and quality of information for decision-making, and a modular architecture that supports the sustainable growth of a collaborative European New Space ecosystem. This poster was presented at the EU booth of the European Commission during the ESA Living Planet Symposium 2025 (LPS25), 23–27 June 2025, Austria Center Vienna, Vienna, Austria, and is co-funded by the European Union.
