| Headline Details: 1 A 3U CubeSat. . Amateur radio signal transmission of digitally stored voice message in Analog FM modulation and digitally stored image in analog SSTV modulation (Scottie 1 format), and 2. Getting the data of geomagnetic sensor and controlling satellite attitude with magnetic torquers using the data. 3. The camera takes a picture of the Earth and transmits the captured data to Earth. The mission period is about two months. The amateur band transmission is open for the public. Voice messages and images digitally stored in the satellite are sent from the satellite to amateur radio stations on the ground by radio communication. This practice will contribute to the improvement of amateur radio communication scheme in the environment of low earth orbit satellites in which Doppler shift and communication time restriction less than 10 minutes are appeared.. Proposing a UHF downlink using 9k6 GMSK, 1k2 AFSK, Analogue voice, SSTV and CW. Planning Interstellar Technologies launch from Taiki-cho Japan into a 2030 km circular 42 degree inclination orbit in Feb 2027 together with OMUSAT-III More info at https://grp.tcu.ac.jp/tac/satellites/tcu-01/ | ||||
