Pre-Conference Workshop Session 1: Coordinating Successful Educational Programs

Utah State University, Logan, UT

Abstract

In this study, we designed and implemented an education using CubeSat educational kit “HEPTA-Sat” to acquire Model-Based Systems Engineering (MBSE) practically. We share the lessons learned there.

In the development of complicated systems such as CubeSat, it is difficult to manage requirements and tasks only in the mind, and omissions and inconsistencies may occur. And, in communication between members and document accumulated in the project, there is often a contradiction with the receiver, since there is implicit information which is not clarified in the background. Therefore, by describing a system in a modeling language and managing it by connecting various related information, it is possible to grasp the whole complicated system and its context, and to succeed project management and knowledge management.

Therefore, we designed a course to practically acquire approach to realize the above system development and conducted it. The course consisted of overview of Systems Engineering, practical assembly of HEPTA-Sat, explanation of the system model, practical training in mission design and modeling, mission implementation and verification, and presentations.

Because modeling is a highly abstract task that describes the structure and behavior of a system graphically, it is difficult for beginners. For this reason, students will practice assembling the HEPTA-Sat, which enables them to learn the basic functions of the satellite system, before handling the system in an abstract manner, and deepen their understanding of the specific system.

In modeling, free graphic drawing tool "diagrams.net" is used, the system is expressed from 3 views (operational, functional, physical), and 2 sides of static and dynamic. A series of flow is presented so that modeling can be performed while maintaining consistency among multiple models. In addition, an example of the mission and system model of HEPTA-Sat was prepared, and it was used to promote the understanding modeling approach.

Mission design, modeling, implementation and verification were carried out as a field of the practice of the learned content. Verification Matrix which arranged the verification item by the retrieval from the model and the report which records the result of the verification were also made. They are connected to model by hyperlink as the simple demonstration of connecting model and context.

Because it was possible to teach consistently with one thing, positive opinions such as "It was easy to understand by dealing with the system from both abstract and concrete aspects." were obtained from the participants. In the last presentation, many students were able to deepen their understanding of the model. Therefore, if the cycle from input to output can be carried out multiple times, it is expected that understanding will improve.
