Paper Abstract

ASTER is an advanced high spatial resolution stereo multispectral optical imager selected for flight on the NASA EOS-AM1 spacecraft in 1998. It is being provided by the Ministry of International Trade and Industry of Japan. The EOS-AM1 spacecraft is being developed under the management of Goddard Space Flight Center. ASTER consists of three telescope subsystems: VNIR, SWIR, and TIR and has a broad spectral coverage from the visible to the thermal infrared. The telescopes have ground resolutions (IFOVs) of 15, 30, and 90 meters, respectively. Because of these high spatial resolutions and the need for close registration of the three telescopes and their internal bands, jitter and stability are important factors in achieving satisfactory geometric and radiometric performances in the instrument's science data products. Integrated finite element model/optical analyses of ASTER jitter and stability were performed as part of an overall assessment of the EOS-AM1 instrument/spacecraft system. Significant disturbance sources and mitigation approaches were identified. The modeling techniques and results are described.
