Abstract

ASTER is an advanced multispectral imager with high spatial, spectral, and radiometric resolutions for EOS-AM1 spacecraft which will be launched with four other instruments in June 1998. The ASTER instrument covers a wide spectral region from visible to thermal infrared by 14 spectral bands. To meet a wide spectral coverage, optical sensing units of ASTER are separated into three subsystems, that is the visible and near infrared subsystem, the short wave infrared subsystem and the thermal infrared subsystem, depending on spectral region. Moreover, ASTER has an in-track stereoscopic viewing capability by a near infrared band. To acquire the stereo data the VNIR subsystem has two telescopes for the nadir and backward viewings. Several new technologies are adopted as design challenges to realize the high performance. The validity of these new technologies is verified through the evaluation of the engineering model.
