The FITSAT-1 CubeSat was developed by students at the Fukuoka Institute of Technology (FIT) in Japan. As well as the optical LED experiment the satellite carries several amateur radio payloads: a CW beacon on 437.250 MHz, a telemetry beacon on 437.445 MHz and a high-speed data downlink on 5840.0 MHz.

Information on how to see the optical beacon signal can be found on the Visual SAT-Flare Tracker 3D site at
