The EO-1 spacecraft, part of the new millennium program, hosts three advanced technologies, the Hyperion imaging spectrometer, the advanced land imager (ALI), and the LEISA atmospheric corrector (LAC) payloads. EO-1 was launched on November 21, 2000 into a sun synchronous orbit behind Landsat 7. Hyperion, which has a 7.6 km swath width, a 30 meter ground resolution and 220 spectral bands, is the focus of this paper. The calibrated spectral bands extend from 400 mn to 2400 mn in 10 mn bandwidths. The initial objectives for the TRW Hyperion team was to characterize the on-orbit performance as thoroughly as possible and to compare with pre-flight characterization test data. On-orbit characterization was followed by research activities carried out by the EO-1 science validation team aimed at assessing the utility of space-based hyperspectral data. This paper provides an overview of the technical innovation and on-orbit characterization of the Hyperion instrument. This paper highlights data collects and analysis methodology of a set of standard and unique data collects that were defined to address specific issues. Sample science applications are also briefly discussed. |
