HISUI Project
HISUI project is carried out by the Ministry of Economy, Trade and Industry (METI), to develop a hyperspectral imager for space demonstration, install it on the Japan Experiment Module (JEM) in International Space Station (ISS) operated by Japan Aerospace Exploration Agency (JAXA) to observe the earth, process and use the acquired data, and demonstrate through all these activities.
Project Outline
Hyperspectral Imager Suite (HISUI) is a spaceborne hyperspectral remote sensing imager developed by Japanese METI.
In optical sensors observed globally with moderate resolution, multispectral sensors that observe more than a dozen bands of wavelengths are currently widely used. In the future, the optical sensors that can observe all continuous wavelength bands in detail, that called hyperspectral sensors, will prove to be very effective in classifying vegetation, minerals, and so on.
Under these circumstances, hyperspectral sensors are being planned or developed mainly in the US and Europe, and the HISUI project is also underway in Japan. HISUI was launched in December 2019 and installed on JEM in ISS. And the global observations with hyperspectral sensor will be realized by HISUI.
HISUI's continuous 185 band which covers the visible to short-wavelength infrared, will provide new information that is currently unavailable, such as the distribution of much more minerals, detailed classification of forests and grasses, and understanding of soil conditions. It has the potential to take remote sensing technology to a new stage.
