Abstract: The increasing complexity of satellite systems, driven by the adoption of Industry 4.0 technologies and strict ECSS standards, demands innovative design methodologies. The METASAT project introduces a model-based engineering workflow that integrates open-architecture hardware with advanced software virtualisation layers, such as the XtratuM hypervisor, to address these challenges. By leveraging a specialised toolchain that combines TASTE with MathWorks tools, METASAT enables efficient code generation for hardware accelerators, including the SPARROW AI accelerator and the Vortex GPU. This paper provides an overview of the project, detailing its design approach, toolchain integration, and contributions towards enhancing satellite on-board software engineering. Through these innovations, METASAT demonstrates how advanced modelling and automated code generation can reduce development costs and timelines, improve system performance, and ensure the competitiveness and dependability of future satellite missions.
