https://directory.eoportal.org/web/eoportal/satellite-missions/s/shindaisat

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.”

ShindaiSat to carry Optical LED Morse Code Beacon

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.

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.

It is expected to launch into a 400km 65 degree orbit from Japan in 2013.

Further transmissions from the optical LED beacon on the amateur radio CubeSat FITSAT-1 are planned for January 10-15. Weather permitting the satellite beacon should be visible using binoculars.

2013, Flashing LED Schedule (times GMT):
10th Jan. 23:57:30 – 23:59:30  New Delhi India        (10Hz Green 2min)
11th Jan. 13:52:30 – 13:54:30  San Francisco USA  (10Hz Green 2min)
12th Jan. 22:00:30 – 22:02:30  Bangalore India        (10Hz Green 2min)
13th Jan. 14:41:30 – 14:43:30  Melbourne Australia (10Hz Red     2min)
14th Jan. 11:03:30 – 11:05:30  Oklahoma USA         (10Hz Green 2min)
15th Jan. 22:27:30 – 22:29:30  Wulumuqi China       (10Hz Green 2min)

The FITSAT-1 CubeSat was developed by students at the Fukuoka Institute of Technology (FIT) in Japan. As well as the optical LED experiment the satellite carries several amateur radio payloads: a CW beacon on 437.250 MHz, a telemetry beacon on 437.445 MHz and a high-speed data downlink on 5840.0 MHz.

New Scientist magazine has an article about Hojun Song DS1SBO and his Open Source Satellite Initiative OSSI-1 CubeSat.

OSSI-1 is planned to launch in the 2nd quarter of 2013 into a 575 km 63° inclination orbit on a Soyuz-2-1b rocket from the Baikonur launch facility in Kazakhstan along with the Bion-M1, SOMP, BEESAT 2, BEESAT 3 and Dove-2 satellites. The Soyuz-2-1b launch had originally been planned for August 2012 but was delayed.

Hojun Song DS1SBO, developer of the OSSI CubeSat, will be speaking at the WIRED 2012 event taking place in London, EC1Y 4SD on Friday, October 26.

OSSI-1 has a beacon in the 145 MHz band and a data communications transceiver in the 435 MHz band. It carries a 44 watt LED array to flash Morse Code messages to observers on Earth. It is planned to launch in April on a Soyuz-2-1b rocket from the Baikonur launch facility in Kazakhstan along with the Bion-M1 and Dove-2 satellites.

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 http://www.uk.amsat.org/?p=10804

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.
