HySIS

HySIS is ISRO's Hyper Spectral Imaging Spectrometer payload, a passive optical hyperspectral imaging spectrometer for Earth-surface observation in the visible, near-infrared and shortwave-infrared regions.^[1][2] It covers 400-2500 nm across 326 detector channels: 70 VNIR channels from 400-950 nm and 256 SWIR channels from 900-2500 nm, with 10 nm spectral sampling.^[2] Ground sampling is 30 m over a 30 km swath.^[2][3] The payload is associated with vegetation and land-cover variables, and its HySIS flight has demonstrated hyperspectral classification, spectral library matching and vegetation-index mapping workflows.^[2] Utilization runs from 2019 to 2026 on an R&D satellite, so buyers should treat it as an operationally flown hyperspectral reference rather than a broad-revisit imaging constellation.^[2]
