3. Cute-1.7Project Overview • Facilitate future microsatellite developments • Radiation protection for commercial devices as black box. • Share experiment opportunities in real satellite • Advanced magnetic-torquer control algorithm Radiation Shield PDA Magnetic Torquer Digital Camera Transceiver

4. Typical Method Verification of each electronic part, e.g. IC. Use of parts qualified to space application. Method in Cute-1.7 Covering normal parts with radiation shield. Redundancy Radiation Protection Radiation protection is the essential issue in space applications To design and demonstrate a radiation shield box in which you can be sure ordinary devices works. It will facilitate satellite design process, then enable easy access to space.

5. Advanced control algorithms are proposed expecting more microsatellites with MTQ >> Cute-1.7 gives opportunities Magnetic Torquers A type of attitude control devices-Interacts with Earth’s magnetic field Simple, reliable mechanism-Best suits microsatellites

7. CUTE-I in News/Presentations (Part of the entire list) • 2003-12-17 Interviewed by Altium Japan. • 2003-10-19 Presentation at 9th Japan Microwave Amateur’s Meeting • 2003-08-23,24 Presentation at HAM Fair 2003 • 2003-07-26 Presentation at Space Development Forum at MeSci • 2003-07-10 Banner near the main gate of Tokyo Tech celebrating CUTE-I launch. • 2003-07-09 Celebration message form Japan Amateur Radio League • 2003-07-04 Celebration message from AMSAT-France • 2003-07-02 Presentation at Space Activity Commission • 2003-06-30 (L-0) CUTE-I LAUNCHED! • 2003-06-27 (L-3) Interview by Kyodo News • 2003-06-20 (L-10) Article on Yomiuri Shimbn • 2003-06-14 (L-16) Article on Asahi Shimbun • 2003-05-30 Interview by Kyodo News • 2003-05-28 Interview by ‘Tech Tech,’ Tokyo Tech’s public relations magazine • 2003-05-19 Interview by Asahi Shimbun • 2003-04-24 Interview by ‘Montyly Playboy’ • 2003-03-10-11 First International CubeSat Symposium in IHJ • 2003-02-17 CUTE-I in NHK TV News • 2003-02-10 Article on Mainichi Newspapers • 2001-11-20 Interviewed by JAMSAT Presentations for specific communities AFTER launch. Newspapers, magazines BEFORE launch. Most of interviews after decided launch date. (Satellite developpers want a wide variety of people to know mission’s outcome, though.)

8. Availability of Rockets • 15 CubeSat will be launched in Fall 2004. • Mr Freddy, Toronto U. is contacting providers. • Launch of piggy-bag satellites depends on main payload. • More satellites ready, more launch opportunities. • Cute-1.7 is based on CubeSat specifications so as to find launch opportunities more easily.

9. Frequency Allocation • Use of Amateur Radio Band • Based on CUTE-I’s success. • Service for Radio Amateurs • Functionality like a repeater will be implemented. Comments by radio amateur FM repeater is interesting for radio amateurs to use. Since there are not many FM satellites, a satellite would have frequent access. Some radio amateurs have exchanged packets with others in the opposite side of Earth using FO-29. I myself haven’t tried it, though. That should be interesting.

10. Closing Remarks • Cute-1.7 is not trying to be prominently technological. • But it will benefit various people: • Researchers and students interested in attitude control algorithms • Developers and users in subsequent nanosatellite projects • Radio Amateurs • ＿＿＿＿＿
