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.
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.
Hyperspectral imaging has wide ranging applications
in mining, geology, forestry, agriculture, and environmental management.
Detailed classification of land assets through the Hyperion will enable
more accurate remote mineral exploration, better predictions of crop yield,
and assessments, and better containment mapping.
