In those days, the development and use of nano-satellite are becoming popular globally, and to increase communication capacity is required. As a solution of this problem, there is free space optical (FSO) communication technology. This technology is researched and developed by ESA, DLR, JAXA, NICT, NASA and so on. NICT developed Small Optical TrAnsponder (SOTA), made experiments of micro-satellite-ground laser communication. We are developing a nano-satellite for hyperspectral remote-sensing, and planning to downlink the image data by optical communication. The purpose of this study is to develop the useful package of optical transmit-receive system on the ground and to develop the space use transmit-receive module. We have been developing proto-type communication module and making experiments at the range of 170m, 1km. This paper shows the evaluation about the range feasible for communication of our proto-type module. On the next stage, we will conduct further experiments at long range, 10 or 20 km.
