Abstract:
The hyperspectral thermal emission spectrometer (HyTES) has been flying science campaigns on a low altitude Twin Otter platform for the past few years. It's now routinely capturing multi-species gas plumes over urban and other applicable environments as well as mineralogical classification over key targets of interest (e.g. Cuprite, Death Valley, etc.). The instrument's thermo-mechanical configuration is being modified to support operation using a higher altitude platform. HyTES uses a thermal infrared Dyson imaging spectrometer. It provides 256 spectral channels between 7.5m to 12m. This paper discusses how the system currently operates and how it's being modified to work on NASA's ER-2 platform. The overall cryovacuum system is being totally redesigned with a significant reduction in both mass and volume. The ER-2 will fly at a nominal altitude of 20km and will provide a 18.6km wide swath with 36m ground pixel size.
