Value proposition
Applying 3D astronomical spectroscopy technology adapted for Earth observation, enabling high-precision hyperspectral data acquisition, processing, and analysis from satellite platforms for agriculture, environmental monitoring, and defense applications
Products and solutions
Hyperspectral satellite payloads (100kg-class and 10kg-class CubeSat), End-to-end satellite observation data platform (acquisition, processing, analysis), 3D high-dispersion spectroscopy technology for Earth observation
Unique value
Only private Korean company developing space-grade hyperspectral imaging technology, leveraging world-class expertise from Seoul National University astronomy and KASI (Korea Astronomy and Space Science Institute), with Korea's first astronaut leading global business development
Target customer
Domestic and international government agencies, private space companies, precision agriculture firms, environmental monitoring organizations, defense/security sectors
Industries served
Aerospace & Defense, Precision Agriculture, Environmental Monitoring, Climate/Energy, National Security
Technology advantage
3D high-dispersion spectroscopy technology originally developed for space telescopes (NISS), adapted for Earth observation; proprietary vacuum/cryogenic chamber for space environment testing; end-to-end platform covering data acquisition to AI-powered analysis
How they differentiate
Only private Korean company in satellite hyperspectral imaging; technology derived from world-leading astronomical 3D spectroscopy (NISS instrument for space telescope); team includes Korea's first astronaut (Lee So-yeon) for global business development; vertically integrated from hardware (satellite payloads) to software (data analysis platform)
