On December 9th, five CubeSats were successfully deployed from the Japanese Experiment Module “Kibo” aboard the International Space Station (ISS). The deployment was part of JAXAs J-SSOD#30 mission and included DENDEN-01, LignoSat, ONGLAISAT, YODAKA and YOMOGI satellites. Two of these satellites, LignoSat and YOMOGI, have received previous IARU coordination to operate over amateur radio frequencies.
LignoSat was developed by Kyoto University and Sumitomo Forestry Co., Ltd. This CubeSat tests the use of wooden materials in space by measuring strain, temperature, and geomagnetism, along with detecting single event upsets (SEU). Amatuer radio satellite enthusiasts were ready to decode telemetry from the satellite this week, but unfortunately there has been no reported reception of either CW or AX.25 packets on the satellite's coordinated frequency of 435.820 MHz.

DENDEN-01 was developed by Kansai University and partner institutions. Its mission includes testing advanced nanosatellite technologies, such as temperature-stabilizing devices, thin solar modules, and compact S-band communication systems. The satellite also supports educational activities and data analysis using a compact hyperspectral camera.
ONGLAISAT is a 6U CubeSat co-developed by the Taiwan Space Agency, the University of Tokyo, and ArkEdge Space Inc. It features a telescope for high-resolution Earth imaging using Time Delay Integration (TDI) technology. This mission aims to produce clear and high signal-to-noise ratio images for Earth observation.
YOMOGI was developed by the Chiba Institute of Technology. Its mission combines environmental monitoring and engineering education. The satellite observes red tide in Tokyo Bay, monitors water pollution in Uganda, and uses APRS to send sensor data to ground stations. Many 4800 baud GMSK telemetry packets have been received and decoded over the last few days indicating that the satellite is functioning well.

YODAKA was developed by ArkEdge Space Inc. and other collaborators. It features a store-and-forward communication mission, collecting and retransmitting text messages from users on Earth, as well as a camera mission to capture Earth imagery. These activities support educational programs at Iwate Prefectural Hanamaki Kita High School and rural revitalization efforts in Hanamaki City.
The deployment highlights collaboration between JAXA, Space BD Inc., Mitsui Bussan Aerospace Co., Ltd., and the J-CUBE program, which fosters academic and commercial utilization of CubeSats. Amateur radio operators and educational institutions are actively participating in tracking and analyzing data from these satellites.
