Abstract:

Model-Based Systems Engineering (MBSE) is a key practice to advance the systems engineering discipline, and the International Council on Systems Engineering (INCOSE) has established the MBSE Initiative to promote, advance, and institutionalize the practice of MBSE. As part of this effort, the INCOSE Space Systems Working Group (SSWG) Challenge Team has been investigating the applicability of MBSE for designing CubeSats since 2011. The goal of the team is to provide a sufficiently complete CubeSat Reference Model that can be adapted to any CubeSat project.

At the core of MBSE is the development of the system model that helps integrate other discipline-specific engineering models and simulations. The team has been working to create this system model by capturing all aspects of a CubeSat project using the Systems Modeling Language (SysML), which is a graphical modeling language for systems engineering. In the past three phases of the project, the team has created the initial iteration of the reference model, applied it to the Radio Aurora Explorer (RAX) mission, executed simulations of system behaviors, interfaced with commercial simulation tools, and demonstrated how behaviors and constraint equations can be executed to perform operational trade studies.

The current, fourth, phase has been focused on the next iteration of the CubeSat Reference Model. The CubeSat Reference Model starts with an identification of potential stakeholders. Each stakeholder’s needs, objectives, constraints, and measures of effectiveness are incorporated into the reference model. The reference model supports all life cycle stages from concept to retirement. The model supports all phases of operations: launch, early operation, and normal operations. The CubeSat Reference Model is built using No Magic Inc. products as the modeling tool set including MagicDraw and Cameo Systems Modeler. Finally, the team is investigating options to share the model with CubeSat designers.
