The KOMPSAT-3A Advantage

Robust Archive
KOMPSAT-3A helps fill in the gaps in the satellite imagery archive. In places with limited high-resolution imagery, KOMPSAT-3A often has available data.

Improved Resolution
KOMPSAT-3A boasts 40-cm resolution satellite imagery, an improvement on KOMPSAT-3’s 70-cm resolution.

Overview & HistoryKOMPSAT-3A SpecificationsPricing

KOMPSAT-3A, when launched in March 2015, was Korea’s most advanced Earth observation satellite. The Korean Aerospace Research Institute (KARI) designed and built KOMPSAT-3. The next generation satellite, KOMPSAT-3A, was a joint venture between the Korean government and private industries with KARI passing its technology on to Korean Aerospace Industries and Asia-Pacific Aerospace. KOMPSAT-3A insures data continuity with KOMPSAT-3 and expands on its capability with 40-centimeter (cm) resolution panchromatic and 1.6-meter (m) four band multispectral data (i.e. blue, green, red and near-infrared).
