Who we are

SPEX develops hyperspectral payloads, data processing pipelines, and analysis solutions for Earth observation applications.

Founded by astronomers, we apply space-proven spectroscopy to Earth observation.


We turn spectral data into insight.

From composition to physical conditions, we extract meaningful information from light.

Each region produces a unique spectral signature.

By analyzing these patterns, we identify composition, temperature, and physical conditions, even from a distance.

Technology proven in space,
now applied to Earth.

SPEX is developing hyperspectral imaging payloads for satellites in Korea.
Today’s spaceborne HSI often relies on push-broom scanning, a proven architecture for wide-area coverage.


Building on this foundation, we explore advanced astronomical techniques to improve spatial-spectral efficiency.


In parallel, we develop end-to-end calibration and validation workflows that transform raw measurements into reliable hyperspectral products.

From data acquisition to insight


SPEX develops hyperspectral data analysis workflows and solutions for Earth observation.

By developing and validating hyperspectral instruments in parallel, we gain a deeper understanding of how spectral data is acquired, calibrated, and transformed into reliable products.

This end-to-end perspective helps us deliver more trustworthy analysis, clearer interpretation, and more practical solutions.

Better data starts with deeper understanding.

→ Drone-based hyperspectral payload over Jeju farmland captured rich spectral data in real-world outdoor conditions.

→ SPEX translated the measurements into intuitive vegetation maps that revealed field variation beyond conventional RGB imagery.

→ This project demonstrates our end-to-end capability in field acquisition, spectral processing, and application-ready mapping.

→ The data revealed subtle condition differences and turned them into clear, interpretable contrast maps.
