Masahiro Arai JN1GKZ reports that six CubeSats delivered to the International Space Station by the HTV-6 will deploy from the ISS using the new JEM Small Satellite Orbital Deployer (J-SSOD) on Monday, January 16.

JAXA ISS CubeSat Deployment 2017-01-16The new J-SSOD has four satellite install cases. One satellite install case has 3U space, so the new J-SSOD could deploy twelve 1U CubeSats at a time.

The six CubeSats are installed as follows:

Case    CubeSats
#1        three 1U CubeSats ITF-2、WASEDA-SAT3、FREEDOM
#2        one 3U CubeSat    EGG
#3        one 2U CubeSat    AOBA-VELOX3
#4        one 3U CubeSat    TuPOD (including Tancredo1 and OSNSAT)

ITF-2、WASEDA-SAT3、AOBA-VELOX3, TuPOD and Tancredo1 have amateur radio downlinks.

#1 and #2 will be deployed at 0900-0930z January 16, #3 and #4 will be 1030-1100z.

Live broadcast will start at 0850z on the JAXA YouTube channel.

On Thursday, February 27 at 1837 UT a cluster of Japanese amateur radio satellites were launched from the Yoshinobu Launch Complex at the Tanegashima Space Center.

At 1948 UT Francisco Jimenez-Martin Sanchez EA1JM received the 437.325 CW (A1A) beacon from the ARTSAT1:INVADER CubeSat.

Also on the first pass at 1952 UT Jan van Gils PE0SAT received
STARS-II (comprises Mother and Daughter satellites)

The student team that developed the ITF-1 CubeSat would appreciate any reports of their satellite on 437.525 MHz FM Morse code, see

An English language article about ShindaiSat is available at

ShindaiSatShindaiSat is a 20 kg spacecraft approx 300 by 300 by 350 mm which is planning to use bright LEDs for Space to Earth optical communication using Morse code. It also carries an optical lens system for receiving modulated LED light from the ground station.

There will be an AX.25 packet radio telemetry beacon and a low power CW beacon. Downlink frequencies of 437.305 and 437.485 MHz have been coordinated by the IARU Amateur Satellite Frequency Coordination Panel.

The article says “A launch of ShindaiSat as a secondary payload is manifested for mid-2014 on the primary GPM (Global Precipitation Measurement) mission of NASA and JAXA. JAXA is providing the launch on the H2A vehicle from the Tanegashima Space Center, Japan.

Orbit: Non-sun-synchronous circular orbit, altitude = 407 km, inclination = 65º.”

On October 4, 2012 five CubeSats were successfully deployed from the International Space Station (ISS). The first pod containing RAIKO and WE-WISH was deployed at 1437 UT while the second pod containing FITSAT-1, F-1 and TechEdSat deployed at 1544 UT. Pictures can be seen at

October 4 was also the 55th anniversary of the launch of the first satellite Sputnik 1. Videos of Sputnik are here.

Four of the CubeSats carry Amateur Radio payloads, they are TechEdSat, F-1, FITSAT-1, and WE-WISH. As of Oct 5, 1015 UT signals had been reported from WE-WISH and FITSAT-1 as well as weak signal reports for TechEdSat.
