JWST IV&V Simulation and Test (JIST) Solid State Recorder (SSR) Simulator

As described in “JWST Integrated Simulation and Test (JIST) Core” (GSC-16739-1) on page 25, the JIST system is a software-based simulator that uses the James Webb Space Telescope (JWST) operational ground system, ground system command/telemetry databases, simulated flight computers, and unmodified flight software binaries to provide dynamic analysis capabilities. There is no hardware in the loop; the flight software communicates over a simulated MIL-STD-1553 and Spacewire port. The JIST SSR Simulator is a reusable component of the JIST system, and is responsible for simulating basic SSR functionality.
