Test and Verification of Nanosatellite HORYU-II and Orbital Anomaly Investigation

Abstract

HORYU-II is a 30 cm-cubic shaped nanosatellite weighing 7 kg developed by Kyushu Institute of Technology. Its main mission is demonstration of high voltage technology. HORYU-II went through extensive tests utilizing the facilities of Center for Nanosatellite Testing at Kyushu Institute of Technology. We reflect on its verification and testing processes of the project that started in April 2010 and ended in May 2012. We consider the effectiveness of each process by comparing the results obtained after the launch that took place on May 18, 2012. Especially, HORYU-II suffered serious anomaly for one month in June 2012 where it could not carry out any missions. We present the result of anomaly investigation.
