Abstract
"Cute-1.7+APD II" is a nano-satellite now being developed at Tokyo Institute of Technology, Laboratory for Space Systems (LSS), which have developed and launched 2 nano-satellites called CubeSat, and the satellite will be the third one in this laboratory. Our second CubeSat named "Cute-1.7+APD" was launched in February 2006 and had worked well for more than 3 weeks. Cute-1.7+APD II is a modified version of the satellite planned to finish all the missions which could not be finished in Cute-1.7+APD. We have added several improvements and have conducted evaluation tests for the satellite in order to make the satellite completely work well in orbit. This paper will explain the total system of the satellite and briefly explain these improvements. Cute-1.7+APD II will be launched from India in 2007 autumn together with 5 university satellites by Polar Satellite Launch Vehicle (PSLV), developed and operated by Indian Space Research Organization (ISRO).
