South Korean communications technology satellite. One launch, 1999.12.21. KOMPSAT was the first joint spacecraft development project for the South Korean aerospace agency KARI (Korea Aerospace Research Institute).
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.
AKA: Korea Multi-Purpose Satellite.

Korea South South Korea became familiar with large-scale rocketry through maintenance and modification activities on American-supplied Honest John and Nike Hercules tactical missiles. By the 1990's Korea had developed an independent capability to manufacture solid propellant rocket motors of up to one tonne mass. In 1990 KARI was funded to build the first indigenous sounding rockets, flown as the KSR-I and KSR-II. In December 1997 KARI was allowed to proceed with development of liquid oxygen/kerosene rocket motor for an orbital launcher, but this was abandoned when the South Korean government decided it wanted to be among the top ten spacefaring nations by 2015. The existing program was too limited in growth potential to allow that. Therefore it was decided to leapfrog the technology by contracting with Russian companies. First launch of the KSLV-I launch vehicle from the new space centre took place in 2010. More...

Associated Launch Vehicles
Taurus American all-solid orbital launch vehicle. Pad-launched launch vehicle using Pegasus upper stages and Castor-120 first stage. First launch used slightly larger Peacekeeper ICBM first stage instead of Castor-120. Under a 2002 contract from Boeing, Orbital developed a three-stage version of Taurus to serve as the interceptor boost vehicles for the US government's missile intercept system. The firm portion of the company's contract, awarded in early 2002, was valued at $450 million and extended through 2007. More...
