Tactical Targeting Network Technology

• Technical Objectives
• Design, develop, evaluate and demonstrate
  wireless technology to provide tac targeting
  network capabilities for tactical aircraft, with
• Low latency (goal 2ms)
• High throughput (goal 10Mbit/s)
• Real-time on-demand capacity allocation
• Complete coexistence with Link 16
• Minimal cost purchase, installation life
  cycle.
• Network planning, monitoring and management tools
  to support tac targeting

• Milestones
• Phase 1 Feasibility 06/02
• Identification analysis of technical issues
• Candidate system definition analysis
• Phase 2 Show me 06/03
• Design, build, fly brassboard systems
• Phase 3 Prove it 09/06
• Build to moderate scale
• Rigorous flight tests.

• Military Impact
• Today
• Only static low rate data links exist for
  tactical airborne platforms, not adequate for
  planned time critical targeting.
• New Capability
• Sensors, shooters and commanders closely
  networked on demand with minimal operational
  overhead, and at very low cost.

TTNT Objective

• Design, develop, evaluate, and demonstrate
  technology required to provide tactical targeting
  network capabilities on
• tactical aircraft, exhibiting
• Responsiveness Low latency, dynamic capacity
  allocation
• High throughput
• Minimal Group A costs No new holes, no new
  cables
• Minimal operational support
• Link 16 Coexists with and is fully interoperable
  with
• JTRS Maximum exploitation of JTRS approach full
  compliance

Offered Traffic

• Traffic controlled by holding off low priority
  traffic as needed. Maintains offered traffic in
  preferred operating region.
• Allows immediate transmission when channel
  conditions permit
• Affords stability by controlling the quantity of
  traffic offered to the channel
• Gracefully degrades as offered load from
  applications increases
• Throughput preserved for higher priority traffic
• Eliminates complexity and traffic overhead
  associated with dynamic TDMA
• Supports scalability well beyond 200 users

• LPI/LPD friendly Channel Access
• Reduced Feature Signal In Space
• Multi-hop Routing
• Silent Node Support
• LPI/LPD Optimized TTNT
• Omni Directional
• SIS Optimization for LPI/LPD
• Additional Very Low Data Rates

Summary

• Currently only static low rate data links exist
  for tactical airborne platforms
• Not adequate for time critical targeting and
  network-centric operations
• TTNT is demonstrating the rapidly
  reconfigurable, affordable, robust interoperable
  and evolvable communications technologies needed
  to support emerging networked targeting
  applications
• Met all system goals
• Completed phase 2 breadboard flight tests
  successfully
• Participated successfully in JEFX04
• On track for scalability flight testing in FY 05
• Clear path for transition to USAF and USN via
  MIDS/JTRS and AMF
