Hyperspectral Imager Suite (HISUI) is a hyperspectral sensor for a remote sensing on the International Space Station (ISS). HISUI is composed of one radiometer that obtains spectral images of 185 bands from the visible to shortwave-infrared region with the ground sampling distance (GSD) of 20 meters for the cross track and 31 meters for the along track. The sensor system is the follow-on mission of the Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) in the visible to shortwave infrared region. The observation data of the hyperspectral sensor is expected to an important role in the future spatial-spectral data for the resource exploration, disaster monitoring, environmental observation, agriculture, forestry and fisheries, etc. The tests of a flight model of HISUI have been carried out successfully in 2019 and HISUI is operating on the ISS. This paper describes the design and the performances of the flight model of HISUI and also presents radiometric performances in orbit.
