Arirang-2

Kompsat, an acronym for Korea Multi-Purpose Satellite is the name of a South Korean satellite series. The program began in 1994 to develop the remote sensing technology in Korea.

Satellite

Kompsat 1 (also Arirang -1) was launched on 21 December 1999 from Vandenberg Launch Complex 576E with a Taurus rocket into a 690 x 722 km sun-synchronous high rail with an inclination of 98.3 °. The 470- kg satellite observed the oceans in the visible and near infrared range. The electro- optical camera (EOC ) had a resolution of about 6.6 m and a swath width of 24 km. He also had particle detectors on board. He was of the Korea Aerospace Research Institute ( KARI ) based on the Northrop Grumman Space Technology TRW Lightsat T200B satellite bus for satellites with about 500 kg in weight and 73 kg of hydrazine as a fuel. TRW was awarded the development contract in the amount of 32 million U.S. dollars on 19 September 1994.

On 28 July 2006, the Russian carrier rocket from Plesetsk brought Rockot from the 800- kg satellite Kompsat 2, also known as Arirang - 2 indicates, on a 685 km high Sun-synchronous orbit. The launch was planned already in 2004, but postponed due to problems with the launcher. As a payload of the satellite the satellite carries a multispectral images 30 ° with a black -and-white spatial resolution of about one meter and a resolution of 4 m to 4 color channels in the range of 450 to 900 nm The swath width is about 15 km, from the vertical can absorb. The data is stored on a solid state recorder. The durability is for three years. The total cost of the satellite system is estimated at 270 million U.S. dollars.

Kompsat 3 ( Arirang -3), which has a similar structure as Kompsat 2, was launched 17 May 2012 (May 18, according to local time) with a Japanese H-IIA rocket.

The satellite Kompsat 5 is equipped with radar ( X-band SAR) instead of optical imaging technique. After the launch was planned for 2012, was announced in the spring of 2013 the Korean Education and Science Minister Lee Ju -ho, that the Dnepr program would be terminated and Korea had to seek an alternative to transport with this rocket. Nevertheless, a Dnepr rocket was provided later, which was built in 1994 as an intercontinental ballistic missile of the type RS -20 and modified for space launches in 2009. The launch took place at Baikonur Jasny on August 22, 2013.
