KOSEN-2 is an educationalnanosatellite jointly developed by eight schools ofNational Institute of Technology in Japan. The satellite would have testedIoT technologies in space. KOSEN-2 was launched on 12 October 2022 by anEpsilon rocket as part of theInnovative Satellite Technology Demonstration-3 mission, but the launch resulted in a failure and the satellite was lost.[1]
KOSEN-2 was a 2U-sizeCubeSat developed by eight colleges of National Institute of Technology. After separating from the launch vehicle the satellite would have extended a directional antenna similar to aYagi antenna. The directional antenna was designed by Kochi College.[2] Kagawa College was in charge of the communication system between the satellite and ground, Gifu College made the satellites's thermal design, Gunma College manufactured its attitude control system, and Tokuyama College manufactured parts using metal3D printers.[3] The project was led by Masahiro Tokumitsu of Yonago College.[4]
KOSEN-2 will would have used its accurateattitude control to point itsdirectional antenna towardsweather buoys. KOSEN-2 would have then received maritime data from the buoys and collect them.[3][5]
