Arirang-1 or Arirang I, also known as KOMPSAT 1 (Korean Multi-purpose Satellite 1), COSPAR 1999-070A, SATCAT 26032, was an unmanned artificial satellite created by the Korea Aerospace Research Institute (KARI) and launched by a US rocket on December 21, 1999. This was the first satellite built primarily by South Korean engineers, although previous foreign-built satellites had been launched by Korean companies. It carried a surveillance camera able to distinguish objects with a diameter of 6.6 meters. It took its name from the popular Korean folk song Arirang.
The satellite was launched from Vandenberg Air Force Base in California on a Taurus rocket. It had been built in Daedeok Science Town in Daejeon, South Korea. The parts were shipped in three stages from Korea to California by First Express International, a Korean shipping firm.
The Arirang-1 was succeeded by the Arirang-2 in 2006. Additional satellites in the series were planned.
On January 6, 2008, the KARI reported that they had lost contact with the satellite. It is suspected to have had a malfunction that has affected power generation. After the loss of contact with the satellite, the mission was formally ended 31 January 2008.
