Automatic Identification Technology (AIT)
2
Background

• FOCUSED LOGISTICS
• Provides situational awareness for military
  operations
• Initiates communication without first being
  activated by the user
• Delivers real-time information regarding the
  condition of equipment

• HOMELAND DEFENSE
• Increases load security for munitions and
  hazardous materials
• Provides carriers with continuous load tracking
• Delivers driver emergency notification
• Provides data sharing of timely and critical
  information
• Authorizes third party emergency response

Radio Frequency (RFID) Tags

• Inventory control functions
• Monitor external inputs such as temperature,
  pressure, chemicals and tamper detectors
• Control outputs such as valves and switches
• Identify an item's precise location
• Active Tags
• Operate with a battery
• Has a battery life of more than 5 years
• Read and write from as far as 100 meters
• Read and write through fences, walls, boxes, and
  file cabinets
• Read multiple tags with a single interrogation
  device
• Passive tags can be read or modified from shorter
  distances

Other AIT Equipment

• RF data collection devices which contain
  transceivers
• RF tag handheld readers/interrogators
• RF relays/repeaters
• RF checkpoint transceivers
• RF base station radios
• Wireless LAN
• Handheld bar code scanners

HERO ISSUE
9
Whats Different

• Violates general guidelines and rules
• 10 foot minimum separation distance
• Use within 4 inches or even touching
• Use in assemble/disassemble and magazine areas
• Use on flight-line and aircraft cockpit
• Typical evaluation methods did not address the
  proximity issue and near-field effects

10
Process StandardizationDevelopment

• AIT Equipment Investigations Conducted
• Identified typical RF emission levels
• Determined effect on sensitive EEDs
• Established safe separation distance criteria
• Findings
• Monopole/Dipole/EED antenna configuration most
  sensitive
• Aluminum fixture .125x14x21 identified as test
  platform
• Separation distances of 4 and 12 inches were
  identified for measurements

• Joint-Service decision to limit the received RF
  signal from AIT equipment to 87dB V.
• Use equipment no closer than 4 inches from
  ordnance.

11
Final Methodology

• Conducted laboratory experiments with EEDs
• Identified minimum coupled RF voltage level (97
  dB V) necessary to induce 15 of MNFC into a 50
  mA EED
• Requires test fixture antennas cut to 50 ohm
  resonance

12
Progress

• Evaluated approximately 100 equipments to date.
• Detected emissions exceeding criterion levels
• Resolutions
• Equipment fixes
• Increase separation distance
• Equipment certification list maintained at NSWCDD

Future Plans

• Publish certification requirements in NAVSEA OP
  3565 and NAVSEA INST 8020.7
• Publish and maintain an approved equipment
  certification list in NAVSEA OP 3565
• JOCG HERO Subcommittee coordinating service
  approval
• Encourage Operational Forces to utilize NAVSEA OP
  3565 authorized equipment list for the placement
  of electronic and electrical AIT equipment near
  ordnance.
