The Navigation, Guidance, and Control (NGC) Department at Sandia National Laboratories conducts flight test programs where rapid proto- typing is essential. To successfully maintain schedule it is critical to have high confidence in the NGC hardware and software prior to integration testing. The NGC Department has developed a V-Model diagram approach to ensure high confidence with hardware and software prior to in- tegration testing within a rapid prototyping environment. The V-Model detailed design process flow describes a design approach for testing hard- ware and software early and often using hardware-in-the-loop (HWIL) and software-in-the-loop (SWIL) simulations.

The Navigation, Guidance, and Control (NGC) Department at Sandia National Laboratories needed a sustainable replacement for a difficult-to-maintain home-grown hardware-in-the-loop simulation visualization tool for spin-stabilized and thrust vector controlled (TVC) rocket system projects. Created and maintained by the Naval Research Laboratory (NRL), SIMDIS, or Simulation analysis and Display), has the capability to display, both as a playback and in real-time, the simulation output of HWIL simulations. Although the playback of simulation data is mostly out-of-the box, real-time display required a custom plugin to be developed and several plugin data flow configurations were explored and the configuration that produced the best results found. Displaying both HWIL simulation truth data and navigational telemetry data side-by-side is possible, and by leveraging SIMDIS display capabilities such as these, the NGC Department has accelerated the flight software development, debugging, and verification and validation (V&V) processes. © 2012 by the American Institute of Aeronautics and Astronautics, Inc.

The Navigation, Guidance, and Control (NGC) Department at Sandia National Laboratories has been developing model-based simulations of rocket systems for preliminary studies, Monte Carlo analysis, and real-time hardware-in-the-loop simulations for flight code verification and validation purposes. Over the years we have developed extensive experience developing model-in-the-loop, software-in-the-loop, and real-time hardware-in-the-loop simulations for rocket systems. This paper describes some strategies the NGC Department has taken to successfully implement model-based simulations for flight test programs. © 2012 by the American Institute of Aeronautics and Astronautics, Inc.
