KOMPSat , an acronym for Ko rea M ulti- P urpose Sat ellite , is the name of a South Korean satellite series. The program began in 1994 to develop remote sensing technology in Korea.

Satellites

KOMPSat 1 (also Arirang-1) took off on December 21, 1999 from the Vandenberg launch complex 576E with a Taurus rocket in a 690 × 722 km high sun-synchronous orbit with an inclination of 98.3 °. The 470 kg satellite observed the world's oceans in the visible and near infrared range. The electro-optical camera (EOC) had a resolution of around 6.6 m and a swath width of 24 km. He also had particle detectors on board. It was developed by the Korea Aerospace Research Institute (KARI) on the basis of the Northrop-Grumman-Space-Technology-TRW- Lightsat-T200B - satellite bus for satellites weighing around 500 kg and with 73 kg hydrazinebuilt as fuel. TRW won the $ 32 million development contract on September 19, 1994.

Start of KOMPSat 5

On July 28, 2006, a Russian Rockot rocket launched from Plesetsk from the 800 kg satellite KOMPSat 2, also known as Arirang-2 , into a 685 km high sun-synchronous orbit . The launch was actually planned for 2004, but had been postponed due to problems with the launcher. The satellite carries a multispectral camera as its payload with a black and white spatial resolution of approx. One meter and a resolution of 4 m on 4 color channels in the range from 450 to 900 nm. The swath width is around 15 km, with the satellite taking 30 ° of the vertical can accommodate. The data is saved on a solid-state recorder. The service life was designed for three years. The total cost of the satellite system is estimated at $ 270 million.

KOMPSat 3 (Arirang-3), which has a similar structure to KOMPSat 2, was launched on May 17th, 2012 (May 18th local time) with a Japanese H-II A launcher.

The KOMPSat 5 satellite is equipped with radar (X-band SAR) instead of optical imaging technology. After the launch was only planned for 2012, the Korean Education and Science Minister Lee Ju-ho was informed in the spring of 2013 that the Dnepr program would be ended and that Korea would have to find an alternative to transport with this rocket. Nevertheless, a Dnepr missile was later made available, which was built in 1994 as an RS-20 ICBM and converted for space launches in 2009. The launch took place on August 22, 2013 from the Jasny Cosmodrome .

The start of KOMPSat 6 and KOMPSat 7 is planned for the end of 2021.

The satellite images are marketed by the Spot Image Group , provided they do not show any part of Korea.
