Rapid Development of Guidance, Navigation, and Control Core Flight System Software Applications Using Simulink Models

The goal of this proposal is to demonstrate a new Guidance, Navigation, and Control (GNC) Flight Software (FSW) application development paradigm which takes advantage of Simulink's auto-coding capabilities using the Simulink Integration Layer (SIL).   This approach will reduce our staffing costs and software development schedule and will increase Goddard Space Flight Center's (GSFC) competitiveness for missions in emerging fields with smaller budgets.

We will demonstrate the usefulness of SIL for GSFC missions by attempting to compile the SIL source code with an autocoded sample GNC application flight software.  We will then attempt to execute the compiled GNC CFS applications on test flight hardware, collect performance data, and then document our results.  If possible, we will attempt to expand its functionality with regards to fault reporting, telemetry processing, and time management.
