Waseda announces the development of a compact artificial satellite
WASEDA-SAT2 will be launched on May 18th

On May 15th, the compact artificial satellite WASEDA-SAT2 was exhibited at the Kansai Satellite Office of the Japan Aerospace Exploration Agency (JAXA) in Higashi-Osaka City, Osaka Prefecture. The satellite was developed by the Miyashita Laboratory and Yamakawa Laboratory of the Faculty of Science and Engineering, and it will be loaded on the H2A rocket which is scheduled to be launched on 6:44 AM on May 18th of this year. Together with the KSAT developed by Kagoshima University and the Negai developed by Soka University, the WASEDA-SAT2 will be grouped and launched with the Venus exploration device Akatsuki. The satellite will circle the earth's atmosphere at an orbit of 300 kilometers.

WASEDA-SAT2 is a cubic satellite which is approximately 10 centimeters on each side and weights approximately 1.15 kilograms. The satellite will be used in experiments such as the projection/filming of QR codes in the satellite orbit and the transmission of data to the earth. Currently, the satellite has been transported to the Tanegashima Space Center (Minamitane-cho) where it is undergoing final adjustments.

Space development is project-based education which realizes the hopes and dreams of students through cooperation with society. Students used their knowledge in machine processing and employed university manufacturing facilities in order to create the satellite. The satellite development was realized by applying various knowledge such as function/capability design utilizing design engineering, capability prognosis and verification using 3 fields of mechanics, and control systems operated by electrical circuits utilizing mechatronics.
