Paper Abstract

ASTER is an imaging remote sensor developed by MITI, Japan, on the platform EOS-AM1 fabricated by NASA, USA. The operation of the ASTER sensor will be jointly performed by Japan and USA. The ASTER Ground Data System (ASTER GDS) will be responsible for keeping track of the sensor status, sending data acquisition schedule and for processing ASTER Level 1 and higher level data. The preliminary design concept was discussed in the literature. The ASTER GDS seems to have several challenging aspects such as: (1) The ASTER GDS handles huge data volume. (2) The ASTER GDS accepts flexible mission operation, including cloud prediction. (3) The ASTER GDS makes a correction for the Band-to-Band misregistration, including inter-telescope registration. (4) User Interface including data search by browse data which will be shown to user electronically, and data acquisition request and data processing request. According to the Data Exchange Principle, the ASTER Data will be delivered at the lowest possible price. Therefore, user community of remote sensing is expected to widely spread and to have a chance to familiarize the remote sensing data. (5) ASTER GDS has a Direct Receiving station which is capable to receive and process high rate data downlinked by X-band, in real time. In this paper, challenging aspects (1) and (2) of the ASTER GDS will be discussed in detail. The issue relating to (3) was discussed in the reference.
