Research on configurable strategy of spacecraft data management system.

The working model for the spacecraft testing has been evolving and will continue changing as this process is going on. This evolvement has aroused challenges to the designs of the spacecraft data management system. The problems include that requirement of the evolving working model could not be satisfied by simply tailoring the functions of the old systems, and that computing resources accumulated in history fails to be effectively utilized to serve the new applications. In response to these problems, this paper proposed a configurable strategy for spacecraft data management system. It contains the following parts: encapsulates basic computing units as components, connectors and component linkage language in which data management system can be developed by manipulating components and connectors. Finally, a part of the system implementation example illustrated effectiveness of the scheme proposed in this paper. © 2011 IEEE.
