摘要

The Second-generation Global Imager (SGLI) on the Global Change Observation Mission (GCOM) is a multi-band optical imaging radiometer in the wavelength range from near-UV to thermal infrared. SGLI will provide high accuracy measurements of Ocean, Atmosphere, Land and Cryosphere. SGLI project is under Engineering Model (EM) phase to design and verify the overall sensor system prior to the Proto Flight Model (PFM) manufacturing. Based on previous Bread Board Model (BBM) results~([1]), the Scanning Radiometer Unit (SRU) and the Electronical Unit (ELU) are under development. The total sensor system verification is planned including not only optical test but also environmental test, such as rocket vibration environment and thermal vacuum environment, so on. This paper describes the current status of the SGLI instrument development.
