STSAT-2C is a research and technology testing satellite operated by the South Korean Korea Aerospace Research Institute . It is the successor to STSAT-2A and the third satellite of the second generation of STSAT satellites.
construction
The three-axis stabilized satellite is equipped with six devices. The Laser Retro-Reflector Array (LRA) enables the orbit of the satellite to be determined with centimeter accuracy by ground stations of the International Laser Ranging Service. The Lagnmuir Probe (LP) is used to determine the electron temperature, electron density and electric field of plasma . The Space Radiation Effects Monitor (SREM) is used to monitor the radiation conditions in near-earth space. In addition, prototypes for testing new space technology are on board with the Reaction Wheel Assembly (RWA), the IR sensor (IRS) and the Femto Seconds Laser Oscillator (BFS). The energy supply is provided by solar cells on two small fold-out wings and on the outside of the satellite with an output of around 80 watts and lithium-ion batteries. STSAT-2C has a planned lifespan of one year.
Mission history
The satellite was launched into a highly elliptical low-earth orbit on January 30, 2013 at 07:00 UTC by a KSLV-1 launcher from the Naro Space Center . This was the first successful launch of a South Korean missile. Contact with the satellite was made for the first time eleven hours after the launch.
As of April 2014, the satellite stopped reporting. Re-entry is expected in 2021.
