The KOMPSAT-2 Advantage

Historical Archive

Kompsat-2 offers a robust archive dating back to 2006, a time period when few satellites collected high-resolution imagery.

Continuous Coverage

KOMPSAT-2 is a bridge of continuous optical imagery collection between KOMPSAT-1 and KOMPSAT-3, providing an archive that goes back to 2000 between the three Korean satellites.

Overview & History

KOMPSAT-2 was launched by the Korean Aerospace Research Institute (KARI) on July 28, 2006. It was modeled after its predecessor, KOMPSAT-1, with a significant improvement on its resolution. KOMPSAT-2 is equipped with 4-meter (m) 4-band multispectral (i.e. blue, green, red and near-infrared [NIR]) sensors and a 1-m panchromatic sensor. It can cover large geographic areas with its impressive swath width of 15 kilometers (km).

KOMPSAT-2 was followed by KOMPSAT-3’s launch in 2012 and continues to provide high-resolution 1-m imagery, far exceeding its original life expectancy and mission parameters. As of September 19, 2022, KOMPSAT-2 has fulfilled its mission and is in safe mode.
