EO-1 Hyperion Instrument

Instrument Summary


The Hyperion instrument provides a new class of Earth observation
data for improved Earth surface characterization. The Hyperion
provides a science grade instrument with quality calibration based
on heritage from the LEWIS Hyperspectral Imaging Instrument (HSI).
The Hyperion  capabilities provide resolution of surface
properties into hundreds of spectral bands versus the ten
multispectral bands flown on traditional Landsat imaging missions.
Through these large number of spectral bands, complex land
eco-systems shall be imaged and accurately classified.





Instruments Overview



The Hyperion provides a high resolution hyperspectral imager
capable of resolving 220 spectral bands (from 0.4 to 2.5 μm) with
a 30 meter spatial resolution. The instrument images a 7.5 km by
100 km land area per image and provides detailed spectral mapping
across all 220 channels with high radiometric accuracy. The major
components of the instrument include the following:


●System fore-optics design based on the KOMPSAT EOC mission. The
telescope provides for two separate grating image spectrometers to
improve signal-to-noise ratio (SNR).

●A focal plane array which provides separate short wave infrared
(SWIR) and visible/near infrared (VNIR) detectors based on spare
hardware from the LEWIS HSI program.

●A cryocooler identical to that fabricated for the LEWIS HSI
mission for cooling of the SWIR focal plane.
