Satellite Radio Reception Experiment Using SDR as a Teaching Material for High School Physics

This is a poster presented at the 6th Shaw-IAU Workshop on Astronomy for Education, organised by the IAU Office of Astronomy for Education (OAE, http//astro4edu.org). Title: Satellite Radio Reception Experiment Using SDR as a Teaching Material for High School Physics Presenter:Uchiyama, Hideki (Shizuoka University) Some artificial satellites transmit radio waves that can be received using amateur radio equipment. Satellite radio reception experiments allow students to observe satellite movements and study high school-level physical phenomena. Kobayashi et al. (2020) showed that these experiments effectively motivate Japanese high school students to learn science. We propose using Software-Defined Radio (SDR) instead of analog receivers for the experiments. SDR enables direct visualization of frequency changes, allowing for the quantitative measurement of satellite velocity using the Doppler effect formula. It offers valuable material for studying Kepler's motion and the Doppler effect in high school physics. We conducted classes with SDR-based experiments and will report our findings.

The Shaw-IAU workshops focus on astronomy education for primary and secondary school students and teacher training both in universities and in service. This year's workshop featured two special topics: an exploration of the first two years of the James Webb Space Telescope for the scientific topic, and the crucial aspect of evaluation in educational contexts as the non-scientific topic.More details can be found on: https://astro4edu.org/shaw-iau/Keep up to date with future Shaw-IAU Workshops and other opportunities at the IAU Office of Astronomy for Education by joining our mailing list https://astro4edu.org/mailing-list/Follow the IAU OAE on Bluesky and Facebook under @astro4edu
