STSAT 3 (Gwahaggisul-wiseong 3)


STSAT-3 (Science and Technology Satellite-3) is a multi-purpose microsatellite designed and developed at SaTReC (Satellite Technology Research Center) of KAIST (Korea Advanced Institute of Science and Technology).

The purpose of the STSAT-3 mission are:

  • A science mission to provide astronomical infrared imagery of the galaxy and of the cosmic background
  • An Earth observation mission to provide infrared and hyperspectral imagery for Earth environmental monitoring, land classification research, and monitoring of water quality.
  • a technology demonstration (engineering objective) mission with the introduction of a composite bus structure, Li-ion battery, LEON-3 on-board computer, and a HPS (Hall-thrust Propulsion Subsystem) with a thrust of about 10 mN
