Paper Abstract

Global Change Observation Mission (GCOM) consists of two series of satellites, GCOM-W (Water) and GCOM-C (Climate) for long-term monitoring of earth environment. Second-generation Global Imager (SGLI), the onboard mission instrument of GCOM-C, is the wide FOV multi-spectral optical radiometer in the wavelength range of near-UV to thermal infrared. SGLI consists of two sensor units, Visible and Near Infrared Radiometer (SGLI-VNR) and Infrared Scanning Radiometer (SGLI-IRS). SGLI will provide high accuracy measurements of Ocean, Atmosphere, Land and Cryosphere. Manufacturing and sensor system integration of SGLI flight models were completed. The sensor system proto-flight tests (PFTs) are on-going including optical characterization tests such as radiometric tests using an integrating sphere and geometric and MTF tests using a collimator. This paper describes development and pre-launch test status of SGLI flight model. Especially we focus on the pre-launch radiometric performances such as the spectral response characteristics and signal to noise ratio.
