For space technology education, we performed the first CubeSat ground model competition for KOSEN (National Institute of Technology) students in Japan, using a newly developed Model CubeSat. Based on the actual operation of the satellite, the events of the Model CubeSat competition were designed to focus on three important subsystems-the electrical power, attitude control, and communications systems. In this paper, we outline the results of the Model CubeSat competition for KOSEN students and discuss the educational merits and further improvements to spread the Model CubeSat competition nationally.
