XI 4, 5 (CO 57, 58, CubeSat-OSCAR 57, 58)
XI IV [ISSL]
The code name of ISSL's CubeSat is "XI" (X-factor Investigator). This derives from its cubic shape (XI means domino in Japanese).
The XI 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, it will establish the development methodology of the small satellite. And by extensively using commercial-off-the-shell components, the total development cost will be drastically reduced and a database on the space-use of the COTS parts will be built. A number of Cubesat-XI prototypes have been built - the fourth is the first flight model with the fifth being its backup.
