The development status of Second Generation Global Imager (SGLI), Infrared Scanning Radiometer (SGLI-IRS)

Global Change Observation Mission, GCOM has two series of satellites, GCOM-W(Water) and GCOM-C(Climate). Both satellites are designed for five years on-orbit life time, and three satellites for each are planned to realize the long time over 11 years continuous global observation. The first satellite, GCOM-W with Advance Microwave Radiometer - 2 (AMSR-2), was already launched in 2012 and is continuously observing the earth for two years, now. The second satellite, GCOM-C with optical radiometer, Second Generation Global Imager (SGLI), is planned for launch in JFY- 2016. SGLI consists of two sensor units, Visible Near Infrared Radiometer (SGLI-VNR) and Infrared Scanning Radiometer (SGLI-IRS). The both flight model sensors are under the manufacturing and integration. This paper describes the SGLI-IRS development status.
