The aerospace industry is currently experiencing a significant transition towards the digitalisation of spacecraft development processes. This shift presents several challenges, including technical limitations in data exchange systems and the increasing complexity of space systems. Over the years, a variety of System Engineering (SE) approaches have been adopted with the objective of managing information as it passes between engineering teams, ensuring consistent design data across different projects and activities, and reducing mission costs and development times. The most relevant of these approaches are Data-Driven Systems Engineering (DDSE) and Model-Based Systems Engineering (MBSE). The DDSE centralises and integrates all space mission engineering data, creating a single source of truth for rapid and collaborative decision-making and enabling faster automation and iteration.
