Hyperspectral Imager Suite (HISUI) is a remote sensing instrument mounted on the International Space Station (ISS). HISUI provides spectral images at 185 bands from visible to short wavelength infrared (SWIR) region (400 – 2500 nm) with the ground sampling distance (GSD) of 20 meters for the cross track and 31 meters for the along track. HISUI is the follow-on mission of the Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) that also covers spectral range from visible to SWIR region. The observation data of the hyperspectral sensor is expected to play an important role in the future spatial-spectral data for the resource exploration, environmental observation, agriculture, forestry, fisheries and so on. The initial checkout for a flight model of HISUI have been successfully carried out in 2019. This paper describes the In-orbit performances such as special, spectral and radiometric. All performance of HISUI in VNIR and SWIR regions fully satisfies the specification, and non-specification items, such as wavelength range, sampling interval, offset, dark noise radiometric sensitivity, are confirmed that the performances of all components are maintained as expected.
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.
