World-class satellite development technology
Although Korea was a latecomer, having begun developing satellites in the 1990s, it has come a long way thanks to continuous investment and R&D, and it is considered to be among the world's top six or seven in terms of satellite development capability. It has secured the world's most advanced satellite design, analysis, assembly, and test technologies to meet various domestic satellite demands. Having constructed a cutting-edge satellite testing facility, it owns satellite operation infrastructure and technology and satellite information utilization technology essential for satellite development.
KARI has accumulated technologies for developing low-orbit earth observation satellites and geostationary satellites applying advanced technologies through world-class satellite research and development. It transfers its satellite development technologies to private industries.
