Spectral Bands
The tables below delineate the spectral characteristics of the hyperspectral imaging sensor on each of the Dragonette satellites. Wyvern strategically operates the hyperspectral imaging sensor on each Dragonette satellite to collect HSI data products with band centre wavelengths that are aligned with existing commercial (e.g., PlanetScope) and science mission (e.g., Landsat, Sentinel, etc.) satellite remote sensing data sources.
