For space technology education, we developed a CubeSat ground model and used it in a production course for students at the National Institute of Technology (KOSEN). The Model CubeSat is designed to make it easier for high-school students to assemble all constituent parts and customize the model. Considering the flexibility to adjust the contents for competitions, the Model CubeSat has a size of about 13 cm cube, is an autonomous device with solar panels, rechargeable batteries, and has long distance wireless communication tools from ZigBee. In this paper, we explain the development of the CubeSat ground model and report the results of its production course.
