KT SAT offers tailored remote sensing satellite data and solutions for diverse industries.
EO(ELECTRO OPTICS)
Electro-Optical (EO) satellite imagery consists of high-resolution images of the Earth's surface, captured using sensors that detect visible and near-infrared light.
BLACKSKY(USA) is a provider of optical imagery with a spatial resolution of approximately 1m (ranging from 0.8m to 1.2m). By operating both sun-synchronous and inclined orbits, it offers a high revisit frequency-up to 15 times per day-making it particularly suitable for surveillance and reconnaissance applications. Image acquisition scheduling and ordering can be managed through the Spectra® platform.

- Suitable for mapping and navigation applications (Swath Width of 13km or more)
-
- Six WorldView Legion satellites with 30cm class resolution are operated in both sun-synchronous and inclined orbits (as of November 2025)
SAR(Synthetic Aperture Radar)
✓ SAR (Synthetic Aperture Radar) is a radar technology that uses a synthetic aperture to image the Earth's surface, capable of operating day or night and in all weather conditions.
✓ SAR imagery enables the identification of terrain and artificial structures based on texture and patterns (speckle). The intensity of the reflected signal varies depending on surface roughness, moisture, and material, creating distinctive differences in brightness.
ICEYE (Finland) operates the world's largest synthetic aperture radar (SAR) satellite constellation, providing SAR imagery with a spatial resolution of up to 0.25m, the fastest SAR image delivery, and the capability to acquire wide-area scan imagery using electronic beam steering, offering unprecedented revisit times to customers worldwide.
