KOMPSAT starts sending science data to Earth
TRW NEWS RELEASE
Posted: Feb. 28, 2000
Developed by Korean Aerospace Research Institute (KARI) and Korean industry jointly with TRW Inc., KOMPSAT is carrying three science instruments. These include two instruments built by TRW for remote sensing applications and a space physics instrument package built by the Korean Advanced Institute of Space & Technology for characterizing the space environment.
"We are pleased with the performance of the instruments and the spacecraft," said Dr. Jang-Soo Ryoo, vice president, KARI. "Data from the remote sensing instruments will help us to gain a better understanding of the Korean peninsula and the oceans surrounding Korea, while the space physics data will help us to understand the effects of space on electronic components."
KOMPSAT's primary payload instrument is an electro-optical camera (EOC), which has started to provide images for the production of digital elevation models of the Korean peninsula. The models will be used for topographical disciplines, such as land development planning, monitoring floods, avalanches and landslides, archeological surveys and hydrological studies. The EOC is a pan-chromatic camera with 6.6 meter resolution.
Both the EOC and OSMI are the latest in TRW's line of air- and space-borne electro-optical instruments to go on orbit.
In addition, KOMPSAT is carrying a space physics sensor that includes a high energy particle detector and an ionosphere measurement sensor. These instruments will enhance the understanding of how the space environment affects microelectronics and spacecraft.
KOMPSAT is based on the TRW family of lightweight spacecraft, a series of modular satellite whose design is readily tailored to mission specific requirements. This family includes the Total Ozone Mapping Spectrometer-Earth Probe and the Republic of China Satellite-1.
The KOMPSAT program consists of two satellites. A protoflight model was built in TRW's California manufacturing facility, and the flight model was built by KARI with assistance from TRW at its Taejon facility.
TRW Space & Electronics Group builds communications, scientific and defense spacecraft for military, civil and commercial customers; produces, integrates and tests payloads; develops advanced space instruments; and integrates experiments into spacecraft. It is an operating unit of TRW Inc., which provides advanced technology products and services for the global automotive, aerospace and information systems markets.
