Due to the rapid acceleration in technology and the drop in costs, the use of commercial off-the-shelf (COTS) PC-based
hardware and software components for digital and hardware-in-the-loop (HWIL) simulations has increased. However,
the increase in PC-based components creates new challenges for HWIL test facilities such as cost-effective hardware and
software selection, system configuration and integration, performance testing, and simulation verification/validation.
This paper will discuss how the Digital Video Timing Analyzer (DiViTA) installed in the Aviation and Missile
Research, Development and Engineering Center (AMRDEC) provides quantitative characterization data for PC-based
real-time scene generation systems. An overview of the DiViTA is provided followed by details on measurement
techniques, applications, and real-world examples of system benefits.
The Aviation and Missile Research, Engineering and Development Center (AMRDEC), System Simulation and
Development Directorate (SS&DD) is developing a Hardware-in-the-Loop (HWIL) facility known as the Multi-spectral
System Simulation (MSS). The simulation facility has the capability to simultaneously produce scenes in three spectral
bands. This paper describes the Near Infrared (NIR) and Imaging Infrared capabilities of the MSS simulation.
This paper will highlight the innovative facility upgrades and modeling techniques that will be utilized to produce hardware-in-the-loop simulations to support both the development and production phases of this Pre-Planned Product Improvement program.
The Air-to-Ground Missiles Systems (AGMS) Project Management Office (PMO) chose to invest in hardware-in-the-loop (HWIL) simulation as an integral part of their Longbow/HELLFIRE (Helicopter Launched, Fire-and-Forget) Modular Missile System program throughout the development and production phases. This investment has resulted in two HWIL simulations, developed by the U.S. Army Aviation and Missile Command (AMCOM) Missile Research Development and Engineering Center, that have had unprecedented success in program support from the early development through production phases. The Millimeter Simulation System 1 (MSS-1) facility is capable of edge-of- the-envelope performance analysis and verification using high- fidelity target, background, and countermeasures signature modeling. The System Test/Acceptance Facility (STAF), developed in partnership with Redstone Technical Test Center, tests full-up missiles for production lot acceptance. Between these two facilities, HWIL simulation is responsible for pre- flight confidence testing of missile hardware and software, software independent verification and validation (IV&V) testing, comprehensive performance evaluation, component verification, production lot acceptance, and data gathering for the shelf life extension program. One payoff of the MSS-1 HWIL investment has been an extremely effective flight test program with MSS-1 receiving credit for saving three flight tests and documenting over 40 failure modes. With the advent of the Performance Based Specification, the MSS-1 has become involved in continuous verification of high level specifications since contractor controlled, low-level specifications are subject to change. The STAF has saved 8 million annually through providing a non-destructive lot acceptance-testing paradigm, and further benefited the production phase by discovering three production problems. This paper will highlight the innovative uses of HWIL simulation as utilized in the Longbow/HELLFIRE program and document the successes demonstrated as this program has transitioned from development into the production phases.
