Ginrei or ShindaiSat 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.
Mission results[edit]
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]
