Abstract
This thesis presents a model-based methodology for Assembly, Integration, and Verification (AIV) of space systems, targeting post-Critical Design Review (post-CDR) project phases. While Model-Based Systems Engineering (MBSE) is increasingly adopted in early life cycle stages, its application to AIV remains limited and largely document-driven. The proposed methodology formalizes AIV through a structured ontology and process model, capturing relationships between requirements, verification activities, criteria, and evidence. Implemented in SysML v1, it enables end-to-end traceability and supports consistent AIV planning, execution, and reporting. Alignment with ECSS verification documentation requirements is demonstrated through model-based artifact generation. The approach is applied to a CubeSat payload qualification campaign. Results indicate improved transparency, consistency, and traceability compared to traditional practices, highlighting the potential of MBSE to support digital continuity beyond early space system life cycle phases.
