Inverting SSB/CW transponder 300 mW PEP.

145.935 MHz BPSK Telemetry 30 or 300 mW.

Orbit: Non-sun-synchronous circular orbit, altitude = 407 km, inclination = 65º.” JAXA is providing the launch on the H2A vehicle from the Tanegashima Space Center, Japan. 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. Downlink frequencies of 437.305 and 437.485 MHz have been coordinated by the IARU Amateur Satellite Frequency Coordination Panel. There will be an AX.25 packet radio telemetry beacon and a low power CW beacon. It also carries an optical lens system for receiving modulated LED light from the ground station.

ShindaiSat 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.

Watch the BBC TV report: Korean artist has high hopes for his homemade satellite Video – How the Amateur Radio Satellite OSSI-1 Works The IARU amateur satellite frequency coordination panel has announced frequencies for a downlink on 145.980 MHz and an uplink/downlink on 437.525 MHz. OSSI-1 is planned to launch on Apinto a 575 km 64.9° 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.

It has a beacon in the 145 MHz band, a data communications transceiver in the 435 MHz band and carries a 44 watt LED optical beacon to flash Morse Code messages to observers on Earth. He has designed and developed it from scratch using readily available components rather than expensive space qualified hardware. The IARU amateur radio satellite frequency coordination panel has announced the frequencies for the OSSI-1 CubeSat developed by Hojun Song DS1SBO.Īrtist and radio amateur Hojun Song DS1SBO has spent 7 years developing his Open Source Satellite Initiative satellite OSSI-1.

Its success showed the outstanding design and construction abilities of the student team from the Fukuoka Institute of Technology. It supported a data rate of 115.2 kbps and sent a JPEG 640×480 VGA pictures in just 6 sec.įITSAT-1’s low orbit meant its lifespan was limited to just 9 months but in that time it was able to achieve a number of technology firsts. The 5840.0 MHz transmitter on FITSAT-1 ran about 2 watts output. FITSAT-1 carried a CW telemetry beacon on 437.250 MHz, a 1200 bps AX.25 packet radio transmitter on 437.445 MHz, a high-speed (115.2 kbps) data transmitter on 5840.0 MHz and an optical LED array to flash Morse code to observers on Earth.
