Transfer of Control Process Objectives

• Simultaneously satisfy operational and tactical
  level requirements for distributed exercises
• Pass control of entities between operational and
  tactical Computer Generated Forces (CGF) systems
  to overcome resolution differences

Transfer of Control Process

• Operational Environment Generator
• Air Warfare Simulation (AWSIM)
• Adequate Operational Level of Fidelity
• Inadequate Tactical Level of Fidelity
• Tactical Environment Generator
• Next Generation Threat System (NGTS)
• Adequate Tactical Level of Fidelity
• Inadequate Operational Level of Fidelity
• DIS PDUs Used for Transfer of Control
• Transfer Control Request
• Acknowledge
• Set Record

JEFX 04 SIT 1 Test Plan

• Technical Test Plan
• Test Transfer of Control over distributed network
• Previous Test was over local LAN
• Test NGTS Manual and Automatic transfer of
  control function
• Use DMOC WTT Virtual and DMOC STAGE Constructive
  simulators
• Test Transfer of Control through DMOC DIS Filter
• Operational Test Plan
• Engage MiG 29 Aircraft after Transfer of Control
• Transfer Red Aircraft back to AWSIM, check fuel
  and weapon status

Manual Transfer of Control Test Results

• Four AWSIM generated red entities successfully
  transferred to NGTS manually
• Entities directed by the NGTS AWACS controller to
  engage two STAGE F-15
• Surviving MiGs transferred back to AWSIM, weapons
  and fuel consistent with NGTS status
• Four additional MiG 29s and 2 MiG 23s manually
  transferred from AWSIM to NGTS
• Problem with NGTS assigning transferred entities
  to NGTS controller
• Manually directed transferred entities to engage
  WTTs, engaged and destroyed NGTS entities

Transfer of Control Initiated

• TCR PULL PDU sent from NGTS to AWSIM
• TCR contains DIS Entity ID of the entity

Transfer of Control Transition

• Acknowledge PDU sent from AWSIM to NGTS
• ACK PDU sent by AWSIM after it has identified the
  entity for transfer
• AWSIM relinquishes control and stops sending
  updates for this Entity
• AWSIM sends Set Record PDU to NGTS
• PDU contains munitions list and available fuel
  (assume 2 different weapon types 2 4)

Automatic Transfer of Control Test Results

• For the AWSIM - NGTS automatic pull for STAGE
  engagement, the automatic TC worked
• Three AWSIM MiGs were automatically transferred
  to NGTS, the fourth had to be manually pulled
• Two MiG 29s were killed by STAGE F-15s, one STAGE
  F-15 was killed by NGTS MiG However
• Destroyed MiGs continued to send Entity State
  PDUs until manually deleted by NGTS
• Entity States sent showed entity destroyed, speed
  set to 0, altitude set to 1 ft.
• One transferred entity showed one call sign, but
  Redsim logger showed another
• NGTS Call Sign XX73 vs AWSIM Call Sign XX304

20
Automatic Transfer of Control Test Results

• For the AWSIM - NGTS automatic pull for WTT
  engagement, the automatic TC did not work
• When the AWSIM MiG 29s were within 60 miles, the
  automatic transfer of control did not initiate
• Three MiGs had to be pulled manually
• Since they were pulled manually, the controller
  was not assigned to these aircraft, and
  therefore, did not engage the WTTs
• Once the controllers were manually assigned, the
  WTTs engaged and killed the MiG 29s

21
Conclusions

• NGTS Automatic and Manual Transfer of Control
  Successful, but improvements are required
• Once NGTS Entities are destroyed, Entity State
  PDU transmission should stop
• NGTS Call Sign should be consistent with AWSIM
  Call Signs
• NGTS Reliability needs improvement
• NGTS Flexibility needs improvement
• Manual Transfer of Control Over-ride Controller
  Assignments
• DIS Filter Successfully read and passed Transfer
  of Control, Set Data, and Acknowledge PDUs
• Incorporate Transfer of Control Study Group
  Changes into NTGS and AWSIM
