Built by students of the Korean Advanced Institute of Science and Technology (KAIST) under a technology transfer program at the University of Surrey's Spacecraft Engineering Research Group - UoSAT in the United Kingdom. KO-23 is operated from The Satellite Technology Research Center (SaTReC) in South Korea.

For further information also see UoSAT & SSTL Satellite Mission Summary and KITSAT-1 Microsatellite Mission.

KO-23 is presently operating as a packet store-and-forward satellite, very similar to UO-22 and KO-25. Ground station requirements are the same for all three spacecraft.

We have just a few of KO-23's images available.
