The dynamical characteristics of the ASTER Ground Data System (ASTER GDS) were analyzed for the various operational conditions. Dynamical system resource allocation mechanizm, non-linearity of data prodessing capability of multiple data transfer and data output, and user requests for higher-level data products were modelled so as to simulate realistic situatiuons. A cloud-free observation was modeled to check response of the heavy-duty operations. The concluding remarks are as follows ; 1) non-lineality has relativly large impact, 2) however the mutiple data transfer has little impact on the system, and 3) the influence of data output is significant. It is also concluded that the performance of this system is sufficient both in normal operation and heavy-duty operation under a typical assumption of the system parameters. Finally, the studies presented in a series of papers demonstrated the effectivness of system dynamical analysis for the performance analysis of the satellite data processing facilities.
