Raijin-2


Raijin-2 is a Japanese micro-satellite launched in 2014. The satellite is built around a 10 cm diameter, 1m focal length Cassegrain telescope and features the following instruments:
All instruments are powered by GaAs solar cells mounted on the spacecraft body, with estimated electrical power of 47.6W. The spacecraft features an unusual central-pillar bus, inherited from the :ja:SPRITE-SAT|Sprite-Sat satellite. The attitude control is done by means of reaction wheels and magneto-torquers, and qualified for 0.1 degrees angular accuracy.

Launch

RISING-2 was launched from Tanegashima, Japan, on 24 May 2014 by a H-IIA rocket.

Mission

The satellite is intended for atmosphere research, especially for gathering statistics on cloud formation and the occurrence of sprites in the upper atmosphere. Mission data are down-linked in S-band with maximal data rate of 38.4 kbit/s.
