“…Developed by the Space Systems Working Group of the International Council on Systems Engineering (INCOSE), the CubeSat SystemReference Model (CSRM) is a SysML model with the following objectives[6]:• "Demonstrate Model-Based Systems Engineering (MBSE) as applied to a CubeSat Mission" • "Develop a CSRM that a university team can use as starting point for their mission-specific model" • "Develop the CSRM as an Object Management Group (OMG) Specification" Finalized in 2021, the CSRM is currently under review at OMG to become a standard[7]. In coordination with the responsible working group, an excerpt of the CSRM describing the reference hardware architecture of a CubeSat has been obtained to serve as a guideline for the Tutorial's model architecture in COMET.According to the CSRM, the following 9 individual subsystems comprise a CubeSat system:•Attitude Determination and Control • Command and Data Handling • Communications • Guidance, Navigation and Control • Mission Payload • Power • Propulsion • Structures and Mechanisms • Thermal Furthermore, each CSRM subsystem contains "Components", as exemplified by the power subsystem in figure 3.…”

As part of the “ESA_Lab@" initiative, a Concurrent Engineering facility has been constructed at the Mechanical Engineering department of Technical University Darmstadt. Concurrent Engineering is a well-proven concept for designing complex space systems and missions in the pre-phase 0/A mission phase. The Concurrent Engineering methodology and processes are enabled by a multidisciplinary team and specific infrastructure in terms of both hardware and software, which generate an effective and time efficient design management system. The university’s “Concurrent Engineering Lab” provides an environment for both researchers and students to explore and apply the Concurrent Engineering approach in areas such as (model-based) systems engineering, Industry 4.0/ Space 4.0, and space traffic management. Furthermore, collaboration with the European Space Operations Centre – also located in Darmstadt – regarding the application of Concurrent Engineering for Ground Segment & Operations has been started. The first addition to the university’s curriculum centered around the Concurrent Engineering Lab will be a “Concurrent Engineering Tutorial”, an opportunity to introduce the Concurrent Engineering methods and tools via hands-on experience to students of the newly established master’s degree program “Aerospace Engineering”. “Tutorials” are elective block courses of the degree program which offer practical learning experiences in many different fields, awarding 4 credit points upon successful completion. Building on the lectures "Fundamentals of Space Systems" and "Space Systems and Space Operations", the week-long “Concurrent Engineering Tutorial” will challenge students to use their acquired knowledge to develop a preliminary design for a predefined CubeSat mission. This Tutorial will not only provide a closer understanding of the individual subsystems of the space segment of a mission, the Concurrent Engineering process and the relevant software “COMET” by RHEA Group but will also create a synergy with a student association of the university, as one of their projects is the development of a CubeSat. This paper describes the background and approach to the development of the Tutorial, in particular the structure of the re-usable model architecture in “COMET”, which was specifically derived and implemented for this purpose and validated via a pilot study
