KOMPSAT-2
KOMPSAT-2 (Korean Multi-purpose Satellite-2), also known as Arirang-2, is a South Korean multipurpose Earth observation satellite. It was launched from Plesetsk Cosmodrome, Russia at 07:45:43 UTC (16:05:43 KST) on 28 July 2006. It began to transmit signals at 14:00 UTC (23:00 KST) the same day. Like the earlier KOMPSAT-1 satellite, it takes its name from the popular Korean folk song Arirang. Its launch was the culmination of a project begun in 1995.
KOMPSAT-2 orbits at a height of 685 km (426 mi), circling the Earth 14 times per day, and is expected to maintain that orbit for 3 years. It weighs 800 kg (1,800 lb). The satellite carries a Multispectral Camera (MSC) which can distinguish to a 100-cm resolution, allowing the identification of individual vehicles on the ground. The satellite was succeeded by KOMPSAT-3, KOMPSAT-5 and KOMPSAT-3A, which were launched in 2012, 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-2 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-1 satellite launched in 1999. KOMPSAT-2 was orbited on 28 July 2006 by a launch vehicle from Plesetsk, Russia. Spot Image was the distributor of KOMPSAT-2 imagery until April 2011. SI Imaging Services is the worldwide exclusive distributor of KOMPSAT imagery including KOMPSAT-2 since November 2012.
KOMPSAT-2 operates in a near-polar, circular Sun-synchronous orbit. The orbital parameters are:
KOMPSAT-2's instruments are designed to acquire high- and very-high-resolution imagery with a footprint of 15 km. The satellite has the capacity to acquire 20 minutes of imagery on each orbit and it can steer its sensors both ways out to 30° off track. Panchromatic and multispectral images can be acquired at the same time.
KOMPSAT-2 radiometer features:
Two receiving stations deliver KOMPSAT-2 imagery 1 to 3 days after acquisition and in under 24 hours in Europe. The Deajeon station in South Korea is responsible for tasking the satellite. The Toulouse station in France is responsible for updating the catalogue, producing imagery and delivering it to its customers.
KOMPSAT-2 is designed for very-high-resolution (VHR) remote-sensing applications, such as:
