Re-post from ANS-245
Seven CubeSats deployed from Japanese Experiment Module “Kibo” on Thursday, August 29.
According to the IARU Amateur Satellite Frequency Coordination, six of these satellites, CosmoGirl-Sat, SaganSat0, SAKURA, Binar2, Binar3 and Binar4, operate on the amateur bands. Three of them carry APRS digipeaters operating on the world-wide APRS frequency of 145.825 MHz.
CosmoGirl-Sat 145.825MHz, 437.120MHz
APRS VHF, callsign JS1YOI
CW, 4k8 GMSK UHF
A 1U cubesat built by Cosmo Girls Amateur Radio Club, a group of Japanese women established under the theme of “Getting closer to the universe.” The satellite also carries a high-resolution camera for earth imaging, as well as a short message UHF store-and-forward system.
SaganSat0 145.825MHz, 437.050MH
APRS VHF
GMSK 4k8, CW UHF
A 1U cubesat built by students at various high schools in the Saga Prefecture of Japan. The satellite also carries an infrared camera and gamma ray detector.
SAKURA 145.825MHz, 437.375MHz
APRS VHF
GMSK 4k8 UHF
A 1U cubesat built by the Chiba Institute of Technology, a university in Narashino, Japan. The satellite also carries experiments designed to monitor sunspots and solar flares, as well as to assess environmental damage on earth.
Binar-2 437.700MHz, Binar-3 437.850MHz, Binar-4 437.925MHz
CW, OQPSK 100/38.4kbps, GFSK 19.2/9.6/1.2kbps
Three cubesats built by Curtin University in Australia designed to test radiation shielding materials and modeling of re-entry data from LEO.
