ChubuSat is a microsatellite of about 50 kg, jointly developed by Nagoya University, Daido University, and the Meiyu Aerospace Support Technology Team (MASTT), a consortium of 24 small and medium-sized aerospace enterprises in the Chubu Region. It was developed with the aims of decreasing satellite costs and lowering the barrier to participate in space development by private enterprise, and expand space utilization by expanding private-sector demand ―goals which align with those of our program. The first satellite, ChubuSat-1(Kinshachi-1) was launched from Yasny, Russian November, 2014 using a Dnepr rocket. One of the projects proposed by our students is expected to be launched as ChubuSat-2 in FY2015.

ChubuSat-1 shown in picture below, its shape is about 50-centimeter cube and weighs about 50 kilogram and is onboard with a visible light camera developed by the Kimura laboratory in Tokyo University of Science, and a store-bought infrared camera.  It has been in tasks to check the following: operating situations on facilities in case of fire occurrence by disaster strike at isolated areas, recognition of volcanic eruption, regular remote monitoring to afflicted district when natural disasters occur, detecting forest fires in remote places, creating the database of debris in space and so on. Message relay service for amateur radio users is also provided. ChubuSat-1 (Kinshachi-1) was launched from Yasny, Russian November, 2014 using a Dnepr after we completed developing the instrument and various tests to put it on-orbit.
