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.

SPROUT amateur radio SSTV satellite to launch in 2014

SPROUT Amateur Radio SSTV Satellite

SPROUT, a 20 x 20 x 22 cm amateur radio nano-satellite with a mass of 7.1 kg, plans to launch with the L-band (1236.5 MHz/1257.5 MHz/1278.5 MHz) Synthetic Aperture Radar (SAR) satellite ALOS-2 on May 24, 2014. [Updated May 19, 2014]

SPROUT (Space Research On Unique Technology) was built by students from Nihon University and its objectives are:

1. Operation of satellite by radio amateurs. SPROUT downlinks the digi-talker sound recorded preliminary in the satellite, the digi-peater voice and packet uploaded by radio amateurs, Slow Scan TV (SSTV) and FM packet of the picture of the Earth taken by the satellite camera, which can be received by radio amateurs. SPROUT has two downlink frequencies and two uplink frequencies, and one uplink frequency and one downlink frequency will be open for radio amateurs. They can use the digipeater and packet and use one camera mounted on SPROUT and take the pictures by themselves, and downlink the pictures by SSTV.

2. Demonstration of the deployment of the combined membrane structure and verification of the design method of the structure SPROUT has a triangular membrane supported by two tubes like framework. They are folded and stored in the satellite before the launch. After the launch, the nitrogen gas is injected into the tubes in space, and they extend, so that the membrane deploys (called “combined membrane structure”).

3. Demonstration of attitude determination and control of a nanosatellite Will conduct the attitude determination experiment on orbit by using the sun sensors, gyros, and geomagnetic sensor, and conduct the attitude control experiment by using the magnetic torquers.

It carries two UHF/VHF radio systems – one for Telemetry, Tracking & Control (TTC) using CW, 1200 bps AFSK and 9600 bps GMSK AX.25 packet and one for amateur operations using 1200 bps AFSK AX.25 packet.

SPROUT plans to launch from the Tanegashima Space Center into a 628 km Sun Synchronous Orbit (SSO) on May 24, 2014.
