The New Space Economy is characterized by the use of standardized and miniaturized components, which, combined with easier access to space, enable cost-efficient space system solutions. Despite the availability of standard satellite platforms and interfaces, modern space services often require the integration of disruptive payload technologies, introducing new engineering challenges. Model-Based Systems Engineering (MBSE) provides a digital framework to integrate such payloads into existing satellite platforms, capturing key design information from stakeholder needs to final system realization. However, satellite digital models are often developed in isolation and tailored to specific mission objectives. Even when based on standard methodologies, the reuse of model elements remains cumbersome and error-prone, leading to risks of inconsistent traceability and functional misalignment across missions. Moreover, existing agile functional modeling approaches are not always aligned with broader digital transformation goals, as they typically rely on graphical notations, which limit model accessibility and make reuse complex and time-consuming. Therefore, this paper proposes an object-oriented functional approach for managing satellite platform digitalization in a modular and reusable manner through functional grouping. An automated framework was developed to support fast, consistent deployment of satellite digital models across missions, leveraging standard solutions and use cases. By enabling configuration and workflow automation, the approach contributes to the System as Code transition in systems engineering. The results demonstrate the potential of combining object-oriented functional analysis with the System as Code paradigm to streamline the development of standard satellite platforms for New Space missions, supporting broader and more effective MBSE adoption.     «
