Description

In this paper, the dynamical characteristics of ASTER Ground Data System (ASTER GDS) were modeled for the study of the system construction. The data flow system of ASTER high rate science data including the imagery and engineering data was modeled by a system dynamics analysis tool, which has "Stocks" and "Flows" in the block diagrams as the fundamental elements. "Stocks" represent data accumulation and "Flows" represent data transfer. The modeled data flow system covered the scope from the observation on the spacecraft to the distribution of the processed data products. The following four partitioning scheme proved to be effective : EOS-AMI Sector, EOSDIS Sector, ASTER GDS Sector, USER Sector. ASTER data observed in EOS-AMI Sector are transmitted to EOSDIS Sector, where they are processed and transported to ASTER GDS Sector. The various products are generated in this sector, then transferred to USER Sector to distribute the products to the world. The effectiveness of system dynamical approach is demonstrated for the analysis of dynamical behavier of the ground data systems.
