KOMPSAT Series

KOMPSAT (Korean Multi-Purpose Satellite) program is a part of Korean government’s space development program, which aims at providing very high resolution satellite imagery to national and international remote sensing society. Since the first launch of KOMPSAT-1 (6.6 m, Optical) in 1999, resolution has been evolved to 55 cm due to the launch of KOMPSAT-3A, and has been widen to X-band SAR satellite imagery. KOMPSAT is dual-use program. Korean Aerospace Research Institute(KARI) is in charge of KOMPSAT operation, and SI Imaging Services (SIIS) has worldwide exclusive distribution rights of KOMPSAT imagery. As a national space program, data continuity of KOMPSAT is guaranteed for both VHR Optical and SAR.
