GinreiorShindaiSat was a 400x400x450mm cube-like microsatellite intended to text experimental visible light communication.[3] 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.
The Ginrei optical signals were received 10 seconds per pass, averaged over 56 passes over the control station.[4] The narrow beam and infrequent operation of optical transmitter have resulted in severe disappointment in amateur optical tracking community.[5]
