Horyu 4 (AEGIS)

Horyu 4 [KIT]

Horyu 4 or AEGIS (Arc Event Generator and Investigation Satellite) is a small technological satellite built by Kyushu Institute of Technology (Kyutech).

Horyu-4 is testing an experimental high-voltage solar array system and observing corresponding spacecraft charging effects on the satellite caused by the high voltage.

The mission of Horyu-4 is to:

  • Acquire current waveform of arcing phenomena on high voltage solar array
  • Acquire image of arcing phenomena on high voltage solar array
  • Advance our knowledge on spacecraft charging
  • Contribute to reliability improvement of present space systems and realization of future high power space system

Horyu 4 was launched piggy-back with ASTRO H and two other small satellites on a H-2A-202 rocket from Tanegashima in early 2016.
