CubeSats are widely used by universities and research institutions all over the world. Their popularity is generally attributed to the use of low-cost components, free student labor and simple design. They have been shown to encourage Science, Technology, Engineering and Math (STEM) students to become involved in designing, implementing and testing a real functioning spacecraft system. Projects like this encourage students from different disciplines to team up to design and build CubeSats, providing interdisciplinary work experience. Participating students vary in their expertise in developing such systems. Some will work on the project for years while others are not willing to spend two or three consecutive semesters developing a CubeSat project. Despite their simplicity in design and low cost, CubeSats are considered great engineering systems for exploring space. Nevertheless, a large number of CubeSat projects fail due to having an unclear mission, ambiguous system requirements and a lack of documentation. Students need to have a clear vision of how to build a real CubeSat system that can be launched and that can function in space. Thus, this paper proposes engineering methodologies and tools to help students develop CubeSat systems. These tools can help students with planning, collecting, eliciting and documenting the requirements in a well-defined manner. This paper focuses on student-driven CubeSat projects designed by students and faculty members. Additionally, data is presented in this paper to identify the challenges and needs of CubeSat developers. Plans for future work are also discussed.

Model-Based Systems Engineering (MBSE) is a key practice to advance systemsengineering that can benefit CubeSat missions. MBSE involves creating a system model that is a single source for system engineering such as architecture development and interface management. The system model also integrates other discipline specific engineering models and simulations. Our application of MBSE uses System Modeling Language (SysML), a graphical modeling language, to model all aspects of a system either directly or through an interface with another model. SysML diagrams are used to describe requirements, structures, behaviors, and parametrics from the system down to the component level. The model is intended for use by aerospace students in their classroom or by a CubeSat team building a mission-specific CubeSat. Using the CubeSat Reference Model as a starting point, a user can populate a mission-specific model with the concept lifecycle stakeholders and stakeholder needs, objectives, constraints, and measures of effectiveness (MOEs) and carry out concept life-cycle studies.

“…Preliminary system design cares about initial and toplevel modeling which are closely connected with user needs. Cubesat models were developed using MBSE in [11]- [13]. Additionally, Cubesat SysML models for specific missions such as the Radio Aurora Explorer (RAX) [14] have been designed.…”

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.
