Flight results of new technology onboard a lean satellite HORYU-IV

HORYU-IV is a 30cm cubic satellite with an approximate mass of 10kg. HORYU-IV carries a high voltage photovoltaic solar array capable of generating a voltage up to 350V. Its main mission is to acquire an arc current waveform by an onboard oscilloscope and capture its image by a camera triggered by the oscilloscope. In addition, it plans to carry out various flight demonstration of new technology. The satellite was successfully launched to an orbit of 575km altitude and 31 ° inclination on February 17, 2016 by H-IIA rocket. Overview of the satellite and its mission are presented.
