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 (LEO). Launched on 26 May 1999 by Indian space agency Indian Space Research Organisation (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.{{cite news|url=http://satrec.kaist.ac.kr/e_02_01_02.php|title=KITSAT series – KITSAT-3|publisher=KAIST Satellite Technology Research Center |access-date=9 July 2016}}{{cite news|title=KITSAT-3|publisher=eoportal.org|access-date=9 July 2016|url=https://directory.eoportal.org/web/eoportal/satellite-missions/k/kitsat-3#foot15%29}}{{cite news|title=Kitsat 3 (Uribyol 3)|publisher=Gunter's Space Page|access-date=9 July 2016|url=http://space.skyrocket.de/doc_sdat/kitsat-3.htm}}{{cite news|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1999-029B|title=KITSAT 3|publisher=NASA|access-date=9 July 2016}} {{PD-notice}}
