TSUBAME is a 30kg class micro-sat planned for LEO to be
launched from Japan 2012. It's the fourth satellite development project
undertaken within the Laboratory for Space Systems at Tokyo Institute of
Technology. TSUBAME demonstrates a satellite platform that can be used for a
variety of engineering and scientific missions. The missions are as follows;

1. Demonstration of satellite bus technology for 30kg-class micro satellite
and verification of COTS components such as micro-processors, memory and
Li-ion batteries in the space environment

2. Verification of Control Moment Gyros developed by the Laboratory for
Space Systems

3. Demonstration of high-speed attitude manoeuvres technology using Control
Moment Gyros. Some sensor data acquisition experiments will be conducted
at the same time in order to demonstrate applications of CMGs.

4. Demonstration of SRLL communication protocol developed by Tokyo Institute
of Technology and high-speed GMSK data down-link
5. Data collection experiment through internet with the aid of radio amateurs
all over the world Proposing to use VHF for telecommand and UHF for
telemetry down-link and a CW beacon. CW beacon coordinated on 437.275MHz.
Down-link AX.25/SRLL, 1200bps AFSK telemetry on 437.505MHz, and S-band BPSK.
