e-kagaku-1 Spacecraft

Educational and amateur radio mission.

1. TNC Development Develop original TNC for ground station and share the know-how to other amateur radio operators. TNC materials that have been developed are listed below. TNC system design overview.
2. Analogue FM Audio Transmission Conduct a digi-talker. Amateur radio operators can receive our voice data. The voice data includes a greeting from the developer.
3. Youth Education Provide education opportunities to junior high and high school students. Students design the systems and participate in operations.
4. SLR (Satellite Laser Ranging) / Non-amateur Mission Measure the round-trip flight time of ultrashort pulses of light to the satellite. Laser irradiation and ranging are performed periodically with the cooperation of JAXA and laser sites in other countries.

• On-orbit demonstration of satellite laser ranging technology using a miniature laser reflector (mini Mt. FUJI).
• Building project-based learning programmes through satellite development. Middle and high school students have been working on this project.
• On-orbit demonstration of integrally moulded frames (Mono Base Frame).
• The operation of the Digitalker function, which can be used by amateur radio operators.
• Original development and technology dissemination of TNC (Terminal Node Controller).
