The hyperspectral thermal imager: High spectral and spatial resolution thermal imaging from a 6U platform

The HyTI (Hyperspectral Thermal Imager) mission, funded by NASA’s Earth Science Technology Office InVEST (In-Space Validation of Earth Science Technologies) program, will demonstrate how high spectral and spatial long-wave infrared image data can be acquired from a 6U CubeSat platform. The mission will use a spatially modulated interferometric imaging technique to produce spectro-radiometrically calibrated image cubes, with 25 channels between 8-10.7 microns, at 13 wavenumber resolution), at a ground sample distance of ~60 m. The HyTI performance model indicates narrow band NEdTs of <0.3 K.
