Pico-satellite "Cute-1.7 + APD II" was developed at Tokyo Institute of Technology, Laboratory for Space Systems (LSS), which have developed and launched 3 pico-satellites called CubeSat. Cute-1.7 + APD II is a modified version of Cute-1.7 + APD and is planned to finish all the missions which could not be finished in it. Several improvements were added and evaluation tests have conducted for the satellite in order to make it completely work well in orbit. Cute-1.7 + APD II was successfully launched on April 28, 2008 by Indian PSLV (Polar Satellite Launch Vehicle) with 9 satellites. This paper will briefly explain these improvements and result of launch and initial operation.
