Kitsat-3

Kitsat-3 was a South Korean remote sensing minisatellite which carried MEIS (Multispectral Earth Imaging System) and SENSE (Space ENvironment Scientific Experiment) instruments to Low Earth orbit. Launched on 26 May 1999 by Indian space agency ISRO, on orbit the satellite was renamed to Uribyol 3. Manufactured by KAIST Satellite Technology Research Center (SaTReC), Kitsat-3 was developed with experience from Kitsat-1 and Kitsat-2 (no heritage to the Kitsat-1 and Kitsat-2 bus) and was the first independently designed South Korean satellite.[1][2][3][4]

Launch

Kitsat-3 was launched in the PSLV-C2 mission by 26 May 1999 by Indian space agency ISRO at 06:22 UTC from Sriharikota Launching Range in India. The launch was the first commercial launch by ISRO of its expendable launch system (PSLV) and $1.0 million (equivalent to $1.53 million in 2019) was charged by the Indian agency for launching and injecting the satellite in the Low Earth orbit.[5]

Mission highlights
  • First independently designed South Korean satellite.
