KOMPSAT-3

Like the earlier KOMPSAT-1 and KOMPSAT-2 satellites, it takes its name from the popular Korean folk song Arirang. Its launch was the culmination of a project begun in 1995. KOMPSAT-3 orbits at a height of 685.1 km (425.7 mi), circling the Earth 14 times per day, and is expected to maintain that orbit for 4 years. It weighs 980 kg (2,160 lb). The satellite carries an Advanced Earth Imaging Sensor System (AEISS), which can distinguish to a 70-cm resolution, allowing the identification of individual vehicles on the ground. The satellite was succeeded by KOMPSAT-5 and KOMPSAT-3A, which were launched on 2013 and 2015 respectively. South Korea started the KOMPSAT programme in 1995 to nurture its national Earth-imaging industry and supply services for remote-sensing applications. The South Korean KOMPSAT-3 Earth-imaging satellite was developed by Korea Aerospace Industries (KAI) and Korea Aerospace Research Institute (KARI), in partnership with EADS Astrium, to assure continuity with the KOMPSAT-2 satellite launched in 2006.
