Abstract :
The end-to-end calibration plan for the Hyperion EO-1 hyperspectral payload is presented. The ground calibration is traceable to a set of three high quantum efficiency p-n silicon photodiode trap detectors the responsivities of which are traceable absolutely to solid state silicon diode physical laws. An independent crosscheck of the radiance of the Calibration Panel Assembly used to flood the Hyperion instrument in field and aperture was made with a transfer radiometer developed at TRW. On-orbit measurements of the Sun´s irradiance as it illuminates a painted panel inside the instrument cover are compared to the radiance scale developed during ground calibration. In addition, an on-orbit calibration lamp source is observed to trace the ground calibration constants determined on the ground to the solar calibration determination. Reference is made to a ground truth campaign at Lake Frome, Australia and a Landsat radiometric comparison
