3 Background Why is instrumentation important? The primary goal of T&E is DECISION QUALITY DATA Effectiveness/performance of System Under Test (SUT) can only be determined from relevant data Good instrumentation design and application can provide useful data for decision makers Often overlooked in context to test methodology How data is collected is as important as the external environment/methodology used to generate it 3

4 Challenges Instrumentation systems are facing constraints on multiple fronts Increasing Complexity of SUTs Data rates increasing dramatically Types of data becoming more varied SUTs becoming multi-layered with multiple participants Decreasing Budgets Instrumentation often the last consideration for Acquisition Program budgets Test-coded aircraft are in shorter supply 4

5 Why Standards? Why is providing effective data instrumentation across the DoD Enterprise a challenge? Often there can be multiple solutions to a single requirement These solutions are often incompatible 5

6 What Standards are Needed? Command & Control Data Transport Imagery (Video/Image/Stream) Media/File Structure External Time Synchronization Data Merge Time Correlation Defined Interfaces to Ground Support Infrastructure 6

11 Benefits of Standardization Promotes Interoperability Open and available to all stakeholders Ensures airborne instrumentation can be effectively used at any test range with any platform Promotes Vendor Competition Prevents vendor lock-in with proprietary interfaces and/or proprietary data formats Lowers barrier to entry for other vendors to provide solutions Promotes agility Using known standard as baseline allows for anticipation of growth (future technology) Incorporate new technology or architectures while maintaining compatibility with legacy systems Planning a solid standard can help to effectively support multiple requirements Vendor X Vendor Z Vendor Y Vendor A More vendors equals More competition equals Better solutions 11
