OSSI-1

Bion-M was launched into orbit at 10:00 UTC on April 19, 2013, from Baikonur Cosmodrome, Kazakhstan, with 6 other small satellites, including OSSI-1.

[1][4] OSSI-1 is the pet project of Hojun Song, a South Korean artist and amateur radio operator.

He worked on it for seven years, designing and building the satellite using off-the-shelf components rather than equipment that had been certified for use in space.

[7] The satellite had a Morse code beacon transmitting "OS0 DE OSSI1 ANYOUNG" on 145.980 MHz and 4 LED lights with a total power of 44 watts to flash Morse code messages, using an open protocol.

[4][7][8][9] According to Korean amateur radio organisation KARL, Hojun Song had some difficulties launching a satellite as a private individual, connected to registering with space bodies and being allocated broadcast frequencies by the international telecoms regulator the ITU.
