∎ STSAT-2c

Following the STSAT-2A and STSAT-2B, the STSAT-2C was the third satellite to be launched from the first Korean-developed launch vehicle KSLV-1 at the Naro Space Center. STSAT-2C has a weight of 100kg, a 300x1,500km elliptical orbit, and was launched on January 30, 2013.

STSAT-2C successfully entered orbit and is currently carrying out missions to verify domestically developed space technologies such as precision orbit technologies (beacon transmission, satellite laser ranging (SLR) via Laser Retro-reflector Array (LRA), Reaction Wheel Assembly (RWA), and Femto-second Laser Oscillator (FSO), as well as conducting space environment observation in an elliptical orbit using the space science payload.
