(Satrec I; Korean: 쎄트렉아이) or SI is a South Korean satellite manufacturing company headquartered in Daejeon, South Korea The company was founded in 1999 by the engineers who developed the first Korean satellite (KITSAT-1) at KAIST SaTRec (Satellite Technology Research Center). The company designs and builds Earth observation satellites called SpaceEye-series, and it provides various space components, including high resolution electro-optical payloads and star-trackers. SI's first satellite was a Malaysian Earth observation satellite, RazakSAT launched in 2009. SI has two subsidiaries: SI Imaging Services (SIIS) is the exclusive image data provider of KOMPSAT-series, and SI Analytics (SIA) provides AI-native GEOINT solutions for satellite imagery. SI also used a spin-off process to establish the SI Detection (SID) company which provides radiation monitoring solutions.²
