Objectives and Applications The goal is to obtain hands-on experience through system engineering, for the students of the Kyushu Institute of Technology (KIT), who developed this satellite. On orbit demonstration of the nanosatellite bus technologies. To safely generate a 300 V photovoltaic power in LEO (Low Earth Orbit) as a high-voltage technology demonstration. The primary goal of HORYU-2 is to demonstrate new solar array designs that can generate power, free of ESDs (ElectroStatic Discharges), by producing 300 V via a specially designed solar array itself, not via a conventional DC/DC converter. If successful, HORYU-2 will become the first spacecraft in the world that achieved 300 V photovoltaic power generation in space. Also, contributing to the local educational program for elementary and junior high school students through HORYU-2 ground communications and the distribution of Earth surface imagery.
