Abstract
This paper describes the architecture and applications of the ZIPSIM series of spacecraft simulators. ZIPSIM is the foundation upon which spacecraft simulators are built at either the register-transfer level or lower level of fidelity. A simulator for a particular spacecraft is built by combining mission-specific components with standard ZIPSIM components. ZIPSIM provides standardized capabilities including utilization of multi-processor hosts, common components (e.g. schedulers, graphical and command-line interfaces, and data displays), reusable models (e.g. processors such as MIL-STD-1750A), uplink and telemetry interfaces related to Mission Operations at JPL, standards for runtime establishment and operation of component interconnections, and a standard command language (Tcl/Tk) for configuring and operating a simulator. An automatic code generator based on the CLIPS expert system is used to generate some of the support code.
