Hojun Song DS1SBO performing final assembly of OSSI-1 satellite on April 9, 2013
The OSSI-1, BEESAT-2, BEESAT-3 and SOMP amateur radio CubeSats lifted off on a Soyuz-2-1a with research satellites Bion-M1, AIST and Dove-2 from Launch Complex 31 at Baikonur in Kazakhstan on Friday, April 19 at 1000 UT. The OSSI-1 CubeSat was deployed from its Pod on the top of Bion-M1 at 1615 UT.

The launch vehicle went into an initial elliptical orbit of 290 km by 575 km orbit at an inclination of 64.9°. A series of orbital maneuvers will be carried out to raise the orbit to 575 km circular before BEESAT-3, SOMP, then BEESAT-2 are deployed at around 1045 UT on Sunday, April 21.
The Center for Operation of Space Ground-Based Infrastructure said the satellites attached to the outer surface of the spacecraft “Bion-M” will be deployed in the period between the 4th and the 35th orbit. It is thought this may mean deployments will take place on the 4th and the 32-34th orbit but that there will be no deployments on the other obits.
OSSI-1 weighs 963 grams
Korean artist Hojun Song DS1SBO has spent 7 years developing his Open Source Satellite Initiative satellite OSSI-1. He has designed and built it from scratch using readily available components rather than expensive space qualified hardware. The launch was the most expensive part of the project costing $100,000.
It has a 12 WPM CW Morse code beacon on 145.980 MHz, a data communications transceiver on 437.525 MHz using AX.25 packet radio and carries a 44 watt LED optical beacon to flash Morse code messages to observers on Earth.
When deployed the OSSI-1 145.980 MHz Morse Code beacon will send “OS0 DE OSSI1 ANYOUNG”.

The development of the OSSI satellite has been documented on the Open Source Satellite Initiative Blog http://opensat.cc/blog/ and the Wiki http://opensat.cc/wiki/
The Korean national amateur radio society KARL described the OSSI-1 CubeSat in their report to the International Amateur Radio Union Region 3 Triennial conference which was held in Viet Nam in 2012. Read the report at http://www.iaru-r3.org/15r3c/docs/019.doc
In this 20 minute video Korean artist Hojun Song DS1SBO and Donghee Park describe the Open Source Satellite Initiative amateur radio CubeSat OSSI-1.
