MBSE for Satellite Communication System Architecting

Abstract

The risk of failure for aerospace missions can be reduced if architects model the product in a systematic way and make decisions for physical implementation based on stakeholder needs. Satellite communication system architecting should take one of its dominating elements, the communication satellite, into account for consistent modeling during the whole product lifecycle. Model-based system engineering (MBSE) serves as a useful tool for system modeling activities and connections with manufacturing. In this paper, satellite communication system architecting is investigated in the preliminary design stage via MBSE methodologies and the system modeling language (SysML). Application scenarios and use cases are built up aiming at satisfying stakeholder needs. System black-box analysis and white-box logical decomposition are further realized. The logical architecture is then partitioned for physical implementation and system optimization is carried out to give architecting suggestions. Requirement traceability is examined to finish the current design stage. The models realized by the MBSE method are reusable and easily extendible to detailed system design and implementation in the whole product lifecycle.

MBSE for Civil Aircraft Scaled Demonstrator Requirement Analysis and Architecting

“…1) An investigation of various MBSE methodologies (as in [10]) and modeling tools (as in [23]) will be helpful to find the best approach for civil aircraft scaled demonstrators. For future work, we will apply MBSE into various demonstrators and compare the effectiveness of different tools and methods.…”

“…Reference [9] presents an MBSE framework using an object-process methodology and incorporating the framework into a model-based design domain for landing gears with dynamic landing constrains. Reusable logical architecture models of satellite communication system is constructed in [10] after a comprehensive investigation of various methodologies. The models have detailed parametric constrains for model-based trade-off analysis.…”

Modellbasierte Umsetzung des Anforderungsmanagements zur Unterstützung der Entwicklung eines Experimentalsatelliten

“…Die Schaffung einer ganzheitlichen Sichtweise auf die jeweilige Problemstellung und eine klare und eindeutige Terminologie spielen bei den betrachteten Arbeiten eine wichtige Rolle. Die Arbeiten [1], [19], [20], [21] und [22] [13] und [25] und den in der Abbildung 5 aufgelisteten Arbeiten die Ergebnisse der Arbeiten [26] und [27] herangezogen. Die in [27]…”

Des Weiteren bietet ein Experimentalsatellit die Möglichkeit, zusätzliche Erkenntnisse bezüglich der Einsatzmöglichkeiten neuartiger Satellitentechnik in einem speziellen Betriebsumfeld zu gewinnen.…”

A Design-Task-Oriented Model Assignment Method in Model-Based System Engineering

“…e most commonly used modeling language in MBSE is the system modeling language (SysML), a general-purpose graphical modeling language that supports analysis, specification, design, verification, and validation of complex systems [11,16], and has been adopted by many MBSE projects [1,9,12,13,17]. Despite the fact that it is accepted by the Object Management Organization as a standard modeling language, SysML is not easy to adapt for system engineers who have not been exposed to object-oriented concepts because, like the unified modeling language (UML), it emphasizes familiarity with these concepts.…”
