- Abstract
The STSAT(Science and Technology Satellite) program is sponsored by the Republic of Korea and is managed by Korea Aerospace Research Institute(KARI). The STSAT-3(Science and Technology Satellite-3 System consists of the STSAT-3 satellite including spacecraft bus, MIRIS(Multi-purpose InfraRed Imaging System) for space observation, COMIS(COMpact Imaging Spectrometer) for earth observation, the ground station, and the launch service segment to place the satellite into the mission orbit (altitude: 400 800km, SSO). The space mission of MIRIS is to make a map of 360*6 degree on galactic plane. Field of view for MIRIS is 3.67 *3.67 degree and it has 3 filters for observation of Pa α band(1.8 1.9 µm). It requires at least one year to complete this mission. Another space mission of MIRIS is to observe cosmic background around the north ecliptic pole with I-band (1µm) and H-band (1.6µm). The secondary payload, COMIS, is for monitoring water, crop and atmosphere. It supports two modes of COMIS observation(strip imaging mode and streo imaging mode). Strip imaging is scanning a target in one direction and the data will be used for monitoring the quality of water and yellow sand in Korea. Streo imaging is scanning one target in three different directions (+50, 0, -50 degrees) on one orbit. Streo imaging data will be used for the observation of a harvest in Korea.This paper describes the top-level operations concept for the STSAT-3 system especially focused on MIRIS and COMIS payloads.
