KOMPSAT programme | |
KOMPSAT-3 (Korean Multi-purpose Satellite-3), also known as Arirang-3,[2] is a South Korean multipurpose Earth observation satellite. It was launched from Tanegashima Space Center, Japan at 16:39 UTC on 17 May 2012. 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.[3]
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.[4]
The satellite was succeeded by KOMPSAT-5 and KOMPSAT-3A, which were launched on 2013 and 2015 respectively.
