The KOMPSAT (Korean Multi-Purpose Satellite) programme is a part of Korean government’s space development programme, which aims at providing very high resolution satellite imagery. Korean Aerospace Research Institute (KARI) is in charge of KOMPSAT operations.
The spacecrafts design for KOMPSAT-2, -3 and -3A is based on an agile platform for fast and precise off-nadir imaging (up to 30º) and single-pass stereo-pair acquisitions.
