Ground Segment Systems Ground Segment Systems Simplifying Ground Segment deployments for Space missions Deimos Ground segment systems are built using a combination of gs4EO products, working in a coherent and synchronized way. We develop several tools and subsystems for the various phases of a satellite mission such as Operational Data Processors, End-To-End Simulators, Payload Data Ground Segments, Flight Operation Segments and EO Data Applications and Services. gs4EO tools are the outcome of the work developed over the years in various Earth Observation missions for ESA, EUMETSAT, National Agencies and Commercial Companies. Related Products GS4EO Ground Segment Systems GS4EO is a suite of tools offering unique and reliable solutions for complete GS or specific subsystems such as data processing, payload calibration and monitoring facilities. Gs4EO is a set of multimission, independent and interoperable modules, designed for maximising mission return and minimize operation and customization costs
