The code name of ISSL's CubeSat is "XI" ([sai]; X-factor Investigator). This derives from its cubic shape ( XI means domino in Japanese), and also represents our investigating spirit toward new knowledge and technology.
We are going to make 3 experimental models before making flight model, and all the models are to be numbered serially (such as XI-I, XI-II, etc.) In our original schedule, XI-IV is to be the flight model, and XI-V will be the back up. After successfully injected to the low earth orbit and becoming our first artificial satellite around earth, that model will be given a friendly nickname other than "XI".
Our CubeSat mission is on-orbit verifications of the technology necessary for super-small satellite system. Acquiring indispensable technology on spacecraft, such as communication, power and electronics, we will establish the development methodology of the small satellite. And by extensively using commercial-off-the-shell components, we drastically reduce the total development cost, and make the database on the space-use of the COTS parts.
