CubeSat Model Based System Engineering (MBSE) Reference Model - Application in the Concept Lifecycle Phase

Abstract

Model-Based Systems Engineering (MBSE) is a key practice to advance systems engineering 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.
