Abstract

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 35 channels between 7.5-11 microns, at 13 wavenumber resolution, at a ground sample distance of approximately 60 m. Measured spectro-radiometric performance indicates narrow-band NEdTs of approximately 0.2K. The small form factor of HyTI is made possible via the use of a no-moving-parts Fabry-Perot interferometer, and JPL’s cryogenically cooled HOT-BIRD FPA technology.
