Development of a Nanosatellite System Modeling Architecture for EIRSAT-1

Over the last two decades, CubeSats which are nanosatellites with form factors based on units (U) of 10 x 10 x 10 cm3, have become more common in academia, enabling students to gain hands-on experience with satellite design, testing and deployment [15]. 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].
