South Korean Aerospace company From Wikipedia, the free encyclopedia
Satrec Initiative Co., Ltd. (Satrec I; Korean: 쎄트렉아이; RR: Sseteurek Ai) or SI is a South Korean satellite manufacturing company headquartered in Daejeon, South Korea[3] 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 spun-off SI Detection (SID), which provides radiation monitoring solutions.[buzzword]

Satrec Initiative was founded in Daejeon, South Korea in 1999. There are two subsidiaries established based on SI's business in the remote-sensing satellite. One is SI Imaging Service (SIIS) founded in 2014, and they provide very high resolution optical and SAR images obtained from KOMPSAT-series and DubaiSat-2. Second subsidiary is SI Detection, and they develops and provides state-of-art radiation detectors derived from spacecraft radiation detecting systems.
SpaceEye-X is a satellite bus, which was originally designed to carry very high resolution optical payload(<0.5 m resolution).[4] SpaceEye-X provides the capability to accommodate various payloads, including SAR antennas.
SpaceEye-1 is an improved model and advanced variant of the SI-300 satellite bus, which was the platforms of DubaiSat-2 and DEIMOS-2. Current model is optimized for Earth observation purposes (<1 m resolution).[5]
SpaceEye-W is a mini-satellite platform (100 kg class). This platform has a very flexible configuration; it can support assorted missions from technical demonstration and science missions to Earth observation missions and telecommunications.
SpaceEye-T is a 700 kg class satellite platform that will form the basis for SI's own Earth observation satellite constellation. It will offer an optical payload with 30-cm resolution and 12 km swath width.[6] As of March 2024, the first SpaceEye-T satellite is planned for launch in 2025.[7]
SI provides Hall-effect electric propulsion systems (HEPS) optimized for small satellite missions. They provide power processing units, propellant feeding units, and Hall effect thrusters with various power consumption range. HEPS has been acquired flight heritages; DubaiSat-2 and DEIMOS-2 equipped HEPS-200 (200 W power consumption).[8]
SI develops and manufactures star trackers that have enormous flight heritages.
