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

4. 4 Radiation Protection 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 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. 5 Magnetic Torquers A type of attitude control devices -Interacts with Earth’s magnetic field Simple, reliable mechanism -Best suits microsatellites Advanced control algorithms are proposed expecting more microsatellites with MTQ >> Cute-1.7 gives opportunities

Newspapers, magazines BEFORE launch. Presentations for specific communities AFTER launch. (Satellite developpers want a wide variety of people to know mission’s outcome, though.) (Part of the entire list)

8. 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. 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. 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. Comments by radio amateur

10. 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 – ＿＿＿＿＿
