KOMPSAT-1 (Korean Multi-purpose Satellite-1), also known as Arirang-1, was a satellite created by the Korea Aerospace Industries (KAI) and Korea Aerospace Research Institute (KARI), and launched by a United States launch vehicle on 21 December 1999. This was the first satellite built primarily by South Korean engineers, although previous foreign-built satellites had been launched by Korean companies. It took its name from the popular Korean folk song Arirang.
