Arirang-2, also known as KOMPSAT-2, is a South Korean multipurpose satellite. It was launched from Plesetsk, Russia at 4:05 PM KST on 28 July 2006. It began to transmit signals at 11 PM the same day. Like the earlier Arirang-1 satellite, it takes its name from the popular Korean folk song Arirang. Its launch was the culmination of a project begun in 1999. Arirang-2 orbits at a height of 685 kilometers, circling the Earth 14 times per day, and is expected to maintain that orbit for 3 years. It weighs 765 kilograms.〔(【引用サイトリンク】title=Multipurpose satellite Arirang 2 set for launch )〕 The satellite carries a high-powered digital camera which can distinguish to a 1-meter resolution, allowing the identification of individual vehicles on the ground.〔(【引用サイトリンク】work=Korea Times ''23 July 2006'' )〕 Among other purposes, this will allow the South Korean intelligence service to observe North Korean military activities. Prior to the launch of this satellite, the South Koreans had been largely dependent upon surveillance information provided by the United States. The satellite was succeeded by Arirang-3 and Arirang-3A, which were launched on 2012 and 2015 respectively. == History == 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 KARI (Korea Aerospace Research Institute), 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 Rockot launcher from Plessetsk, 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Arirang-2」の詳細全文を読む スポンサード リンク
