Development of the Earth Observation Camera of MIRIS

Abstract

6Green Optics Co., Ochang 363-883, KoreaWe have designed and manufactured the Earth observation camera (EOC) of multi-purpose infrared imaging system (MIRIS). MIRIS is a main payload of the STSAT-3, which will be launched in late 2012. The main objective of the EOC is to test the operation of Korean IR technology in space, so we have designed the optical and mechanical system of the EOC to fit the IR detector system. We have assembled the flight model (FM) of EOC and performed environment tests successfully. The EOC is now ready to be integrated into the satellite system waiting for operation in space, as planned.

Thermal Analysis of MIRIS Space Observation Camera for Verification of Passive Cooling

“…MIRIS will perform multipurpose observation with two infrared (IR) cameras: the space observation camera (SOC) and the earth observation camera (EOC). The EOC will observe the Earth (particularly the Korean peninsula) to monitor forest fires, volcanoes, and the vegetation index (Lee et al 2011). The SOC, on the other hand, will survey the Galactic plane to study the origin of the warm ionized medium through emission line survey and measure the absolute cosmic infrared background level through imaging in I and H bands, with a wide field of view (3.67 × 3.67 degree) in the wavelength range from 0.9 to 2 μm (Han et al 2010).…”
