Benefits of Early Testing

Government System Integration Lab (SIL)Testbed:– Rapid experimental prototyping for integration and performance assessments

– Build Incremental Confidence, Risk Reduction, and Cost Savings/Avoidance

– Verify & Validate contractor designs, requirements of HW, SW, Interfaces, TDP, and M&S

– Use M&S to perform iterative Digital Engineering monte carlo (off-nominal) performance runs

– Perform pre/post GT/FT predictions/reconstruction and off-nominal testing

– Perform quick-turn, independent assessments and what-if exercises

– Conduct Quality and Reliability Assessments

– Support Urgent Material Release decisions with key performance Caps and Lims

– Opportunities for Crew Training & Feedback

Integration Testbeds consists of:– System Integration Lab (SIL) with Processor-in-the-loop (PIL) & Hardware-in-the-Loop (HWIL) for Testing

critical Battery Operation Center (AFATDS & Mission Planner), Launcher/canister, Fire control, and Missile AUR hardware, software, firmware, interfaces, and cables

Establishes an integrated, comprehensive, capability with the HW, SW, IFs and M&S for each flight test while immersed in a realistic and rapid prototype testing environment

Inertial Measurement Unit Stimulation Capabilities

• Stimulates the IMU with rigid (line-of-sight) and flexible body (vibration) environments

• IMU sees true line-of-sight (TLOS) angular stimulation allowing the gyro output to be fed back directly into the simulation

• Improvement over all-digital approximation or a synthetic line-of-sight (SLOS) configuration where the gyros only see relative motion

• Measurement precision of the gyros is preserved along with their dynamic response (linearity) and noise

IMU Closed Loop HWIL provides:

• Flight Test Risk Reduction• High Frequency Anomaly

Detection• Ground Test Environments

• Rigid Body (LOS)• Flexible Body

(vibration)

SIL provides specialized high fidelity stimulation
