Hancom InSpace announced on the 19th that it will launch "Sejong-3," Korea's first private hyperspectral satellite, aboard SpaceX's Falcon 9 rocket on the 29th of this month (local time). Through this launch, the company plans to expand its satellite data business by adding hyperspectral observation capabilities to its existing Sejong series observation system.
Sejong-3 is a 6U-class microsatellite measuring 200mm x 100mm x 340mm and weighing approximately 10.8kg. It will conduct Earth observation missions from low orbit at an altitude of 500-600km, equipped with a hyperspectral sensor. The core payload, a hyperspectral sensor, collects image data capable of analyzing the unique reflective properties of materials based on 442 wavelength bands.
Data obtained through hyperspectral observation will be utilized in agriculture and forestry sectors. It can support precision agriculture by identifying crop growth conditions and stress factors, and detecting potential disease outbreaks early. In forestry, it enables precise environmental management including tree species classification, forest damage monitoring, and wildfire risk zone analysis.
Hyperspectral data applications can also extend to advanced surveillance and reconnaissance areas, such as identifying camouflaged or concealed objects and analyzing surface materials. As material property-based analysis becomes possible beyond simple image interpretation, more precise and reliable information can be provided.
Hancom InSpace entered the NewSpace market in 2022 by successfully launching Sejong-1, Korea's first private commercial Earth observation satellite. Beyond satellites, the company provides industry-specific customized solutions through "InStation," a multi-source intelligence fusion AI analysis platform that integrates data from satellites, drones, and ground sensors. Based on this foundation, the company's strategy is to solidify its position as a high-value-added data service provider that delivers decision-support information beyond simple imagery across various sectors including agriculture, environment, and defense.
A Hancom InSpace official said, "Sejong-3 features next-generation hyperspectral observation technology capable of precisely analyzing material properties beyond just photographing the ground." The official added, "We will continue to strengthen our competitiveness in the global satellite service market by combining our unparalleled ultra-precision data acquisition capabilities with our proprietary platform technology."
