The main mission of EOC is cartography to provide the images for the production of 1/25000-scale maps of the Korean territory. EOC collects 510 by 730 nautical mile panchromatic imagery with the ground sample distance of 6.6 m and the swath width of 17 km by push broom scanning. EOC also can scan ±45 degree across the ground track using body pointing method. Though the main mission of EOC is for Korean peninsula, it can be extended to the worldwide mission through direct oversea data reception or using 2.5 Gbit Solid State Recorder at end of life.
OSMI is worldwide ocean color monitoring for the study of biological oceanography. It will generate six-band ocean color images with 800 km swath width and 1 km ground sample distance by whiskbroom scanning. OSMI is designed to provide on-orbit spectral band selectability in the spectral range from 400 to 900 nautical mile through ground command. This flexibility in band selection can be used for various applications and will provide research opportunities to support the next generation sensor design.
SPS consists of the High Energy Particle Detector (HEPD) and Ionosphere Measurement Sensor (IMS). HEPD has missions to characterize the low altitude high-energy particle environment and to study the effects of radiation environment on microelectronics. IMS measures densities and temperature of electrons in the ionosphere and monitors the ionospheric irregularities at the KOMPSAT-1 orbit.
KOMPSAT is based on TRW Space & Electronics Group's family of lightweight, standardized spacecraft bus adapted to fit KARI's specific mission requirements.
In March 1995, TRW signed a contract with the Korea Aerospace Research Institute to jointly develop with KARI and Korean industry a new lightweight, multi-purpose satellite. It represents the first joint satellite development project ever undertaken by KARI and is a key step forward for the Republic of Korea in its quest to become a self-sufficient, space-faring nation. Over the last five years, engineers from KARI and Korean industry have worked side by side with TRW engineers to produce two complete, ready-to-launch satellites and to acquire expertise in designing, building and using satellites to satisfy Korea's key environmental and scientific goals.
The primary purpose of the protoflight model was to verify the structural and functional design of the satellite. It serves as a back-up for the flight model, should the need arise. Some hardware for the satellite's electrical, thermal, structural, and propulsion subsystems was produced in Korea by Korean industrial partners. TRW provided on-site assistance to these Korean partners to ensure that the components were properly produced and prepared for integration into the spacecraft. The second satellite, the actual flight model, was assembled, integrated, and tested at KARI facilities in Taejon, Republic of Korea, by KARI engineers with support from TRW personnel.
