STSAT-2C (Science and Technology Satellite-2) is the third satellite launched by the Naro-1 (KSLV-1) launch vehicle, at Naro Space Center, Korea in 2013.

STSAT-2C carries six payloads:

  • the Laser Retro-reflector Array (LRA) allows the spacecraft to be tracked with centimeter accuracy by satellite laser ranging (SLR) stations which make up the International Laser Ranging Service (ILRS).
  • a Langmuir probe will be used to determine the electron temperature, electron density, and electric potential of plasma.
  • the Space Radiation Effects Monitor (SREM) will be used for measurements and monitoring of the near-earth space environment.
  • in addition, the Reaction Wheel Assembly (RWA), IR Sensor (IRS), and Femto second Laser Oscillator (FSO) are carried for the verification of new space technologies

STSat 2C successfully reached orbit after launch on 30 January 2013. It operated until April 2014, when contact was lost. It reentered on 13 November 2019.
