HLA Experimental Objective of Use Case
  • Apply HLA technology to real simulation
  • Develop hands-on capability
  • Develop Toolset to support HLA simulation
    development
  • Determine capabilities/constraints for
    applicability of HLA to RDE domain

3
Experiment Description
  • Live flight and HWIL simulations integrated with
    theater wide virtual simulations
  • Applicable to requirements analysis, engineering
    trades, test evaluation
  • Uses mostly legacy systems and simulations,
    linked via a common API design

System Testbed Sites
  • Expand Early Use of MS
  • Evolve simulations from
  • cradle to grave
  • Common environment for
  • performance evaluation
  • - Concept of Operations
  • - Design-to specifications
  • - As-built design
  • - Operational tests
  • Technology Insertion

TTV-1 Test Overview
  • Test Target Vehicle
  • ALI target
  • Single stage
  • Non-separating
  • ALI ScenarioVersion 1.3Ship positons

7
HLA Characteristics of Simulation
  • Used RTI 1.0.3 for this experiment
  • Initially based on RPR FOM, but much tailoring
    needed
  • HLA time stamps generated by extraction and
    alignment of time stamps in data sources
  • Propagation algorithms used to offset latencies

8
HLA Toolset
  • Used RTI (1.0.3)
  • Developed/maintained Common API
  • Developed data storage and retrieval tools
  • Developed replay and data monitoring tools
  • No current HLA compliance check
  • Need exists for a exercise management tool

9
Lessons Learned
  • Early use of MS is valuable
  • Identify critical/sensitive design parameters
  • Accelerate completion of design trades
  • MS supplements HWIL simulations
  • Monte Carlo runs
  • Expand performance windows
  • Minimize complexity
  • HLA technology is usable now
  • Maturity limits degree of integration
  • Legacy systems restrict applicability
  • Reduces integration efforts (schedule,
    complexity, error detection)

SBA (R)evolution at RMSC
  • Engineering simulations can be integrated
    real-time with range flight and sensor data
  • Confidence in system effectiveness trades
    increased
  • Acceptance of MS as supplement to flight tests
  • Promote design reuse of MS tools

HLA Performance
  • Fedex Blocking error recurs unpredictably
  • RTI overhead increases bandwidth significantly
  • Alignment of time stamps critical
  • Essential to understand derived effective
    simulation errors due to the timing errors
  • Difficult to design class structures to allow
    selective subscriptions
