Korea Aerospace Industries (KAI) and Hanwha Systems are vying to construct 40 ultra-small synthetic aperture radar (SAR) satellites for South Korea, designed to monitor the region every 20-30 minutes. The project, estimated to cost 1.2-1.3 trillion won, is set to begin satellite launches later this year, with a contractor selection expected in October. KAI aims to reduce costs using commercial components, while Hanwha collaborates with Satrec Initiative for integrated designs, with launches planned through SpaceX and the Korea Space Launch Vehicle II.
