Satellite Instruments
Hyperion, the first successful operational hyperspectral sensor, was launched in November 2000 on the NASA EO-1 satellite. EO-1 was the first mission in NASA's New Millenium Program, had a one year design life, and focused on validation of new technologies. Instruments have performed almost flawlessly, and the mission operations funding has been extended through 2011. Hyperion's system fore-optics include a single telescope which provides for two separate grating image spectrometers to improve signal-to-noise ratio (SNR). Data are collected in 242 contiguous (ave) 10nm bands using a focal plane array with separate VNIR and cryocooled SWIR detectors. 198 bands are calibrated due to spectral overlap of the VNIR and SWIR and low response of bands at short wavelengths. Radiometrically and terrain corrected operational products are available as 16-bit radiance data. The fine spectral resolution of the Hyperion instrument has provided opportunities for a wide range of applications in land cover mapping, including minerals exploration, forestry inventory and stress monitoring, crop discrimination and monitoring, wetlands, soils characterization, and arid land applications. The narrow spectral bands also provide capability for spectral unmixing for sub-pixel mapping and greatly improved atmospheric correction of scenes. It is considered as a prototype for future spaceborne hyperspectral missions and is being utilized both operationally and as a testbed for future missions.
