As a professor at KAIST, he created the KAIST Satellite Technology Research Center and led a collaboration with students from KAIST and the University of Surrey to successfully engineer the first Korean satellite, KITSAT-1, also named "Our Star." The satellite was successfully launched from the Guiana Space Center in 1992.
