Abstract

The 2U-size cubesat RAIKO was launched to the International Space Station (ISS) in July 2012, and released to space in October 2012. The preset sequences of the 30-min initial separation phase were successfully carried out, and 46 photos were taken and stored to memory by the onboard CMOS and CCD sensors. Four Japanese universities collaborated in joint operations of RAIKO, which included successful S-band command/telemetry operations at a telemetry downlink rate of 100 kbps using the 100-mW onboard transmitter. In addition, Ku-band beacon signals were successfully monitored to determine the orbit and atmospheric disturbances. This paper presents an outline of RAIKO, the ground station network, the operation method, and associated results. The cubesat RAIKO inherited the satellite bus technology of a 50-kg microsatellite, and various technology demonstrations were achieved. Through the joint operation of RAIKO, the ground station network was practically improved and will contribute to the operations of future micro- and nanosatellites.
