The use of Commercial-Off-TheShelf (COTS) components reduces development cost and time, making CubeSats an accessible and cost effective route to space. CubeSats are increasingly important for in-orbit demonstrations of new technologies. Further, their flexibility allows them to be configured for a wide range of science mission profiles, either as a standalone platform, as a communications relay for lunar and inter-planetary missions, such as NASA's Mars Cube One (MarCO) satellites [14], or as a daughter spacecraft to study a near-Earth object such as LICIACube [2]. Several CubeSats for high energy astrophysics are currently in orbit and in development [9].enModel-based systems engineering (MBSE)CubeSatsSystems engineeringVerification and validationSatellite communicationsConference Publication10.1109/SMC-IT56444.2023.000222024-01-0919/FFP/6777https://creativecommons.org/licenses/by/3.0/ie/
