The radiometric, geometric, and spectral performances of the ASTER instrument were confirmed in the Proto Flight Model (PFM) tests and it is necessary to optimize the operation scenario for efficient data acquisition.
Abstract
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a high spatial resolution multi-spectral imaging radiometer, and spectrally covers the visible and near-infrared, short-wave-infrared, and thermal infrared regions with 14 spectral bands, 15 to 90m spatial resolution, and 60 km imaging swath. ASTER has the along-track stereoscopic viewing capability with BH of 0.6 and cross-track pointing function for global coverage. Several new technologies such as long-life active cryocoolers are adopted to realize high observation performances. The radiometric, geometric, and spectral performances of the ASTER instrument were confirmed in the Proto Flight Model (PFM) tests. Since operation of the ASTER will be limited by various constraints such as duty cycle and pointing change controls, it is necessary to optimize the operation scenario for efficient data acquisition. Prioritization of data acquisition requests will be based on factors such as data category, user category, and science discipline.
