Ginrei
Ginrei or ShindaiSat was a 400x400x450mm cube-like microsatellite intended to text experimental visible light communication. The satellite is made in Shinshu University (Japan). The ground station was completed by 18 March 2014 and attempts to communicate with satellite have started the same day. 2-way optical communication with ground station is planned. Also, advanced attitude control using visible light communication is planned as well.

Mission results
The Ginrei optical signals were received 10 seconds per pass, averaged over 56 passes over the control station.[3] The narrow beam and infrequent operation of optical transmitter have resulted in severe disappointment in amateur optical tracking community.[4]
gollark: Why?
gollark: The shallowness is probably fine! The problem is that you don't actually have to think very hard for most of the content here.
gollark: The answer is obviously π, but that isn't the point.
gollark: But rigor and problem-solving-ness aren't the same thing either.
gollark: It does slightly teach the theory. It's just very bad at it.
