Satrec Initiative Co., Ltd. (Korean: 쎄트렉아이) or SI or Satrec I is a South Korean satellite manufacturing company headquartered in Daejeon, South Korea[2] The company was founded in 1999 by the engineers who developed the first Korean satellite (KITSAT-1) at KAIST Satellite Technology Research Center (SaTRec). The company designs and builds Earth observation satellites platform called SpaceEye-series, and SI provides various space components, including high resolution electro-optical payloads and star-trackers. SI's market entering began with a Malaysian Earth observation satellite, RazakSAT. SI has two subsidiaries, SI Imaging Service (SIIS), which is the main image data provider of KOMPSAT-series and SI Detection (SID), which provides radiation monitoring solutions.
History
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.

Platforms
SpaceEye-X
SpaceEye-X is a satellite bus, which was originally designed to carry very high resolution optical payload(<0.5 m resolution).[3] SpaceEye-X provides the capability to accommodate various payloads, including SAR antennas.
SpaceEye-1
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).[4]
SpaceEye-W
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.
Subsystem-level Products
Electric Propulsion Systems
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).[5]
Star Tracker
SI develops and manufactures star trackers that have enormous flight heritages.
