AKA: Arirang;Korea Multi-Purpose Satellite. Status: Operational 1999. First Launch: 1999-12-21. Last Launch: 2015-03-25. Number: 4 . Gross mass: 470 kg (1,030 lb).

TRW and Korean engineers worked together to develop the spacecraft.

The payload consisted of several scientific instruments as well as a Ka-band communications device. KOMPSAT was based on TRW's Eagle class of light weight, modular spacecraft. It had 3-axis stabilization with dual solar arrays. The payload included a 10 m resolution CCD imaging system supplied by Litton Itek Optical Systems. TRW supplied a low resolution camera for ocean and Earth resources monitoring. Other scientific instruments included a device to measure Earth's ionospheric and magnetic fields and a high-energy particle detector.

TRW signed the $ 32 million contract to develop the satellite on 19 September 1994.
