  • Final assembly
  • Wing manufacturing
  • May or may not have good infrastructure (power and network) in all locations
  • Tools often expensiveLast known location often good enoughBasic requirement is to find a toolSets of tools may need to be kept togetherAlso requirements that certain tools should be restricted to/from certain areas (e.g. right wing)Potentially indoor, outdoor, storage containers, in transit
  • Often location implies stage in processWant ability to define areas with entry and exit eventsAction may depend on more than just location (could pass through same location multiple times, action depends on previous steps)Sometimes track associated paperworkPotentially indoor, outdoor, in transit
  • Major value in this in coordinating distributing manufacturingVisibility across multiple plantsProduction integration“VIP” – visible industrial process (do we use this term?)
  • Automated setting of tool configuration (e.g. torque settings) based on location of tool and assemblyConfirmation that correct tool operations carried outMore common in auto but applicable to aero
  • Inside wings or other assembliesIn outdoor test areas – stray items likely to be stored in nearby containers
  • Less flexibility to change workflowsOften limitations on location of infrastructure on the building floorLess applicable to applications like tool tracking
  • Good balance of high accuracy with relatively low infrastructureVery flexible for granular workflow trackingSame infrastructure applicable for tool tracking, control, etcTypical accuracy ~1ft, depends on environment
  • TDOA only versus AOA optionSeparate communications channel (for tool control and feedback, varying tag update rates, etc)Characteristics of tags – form factor, battery life, etcIntrinsically safe required?Integration with other technologies – presence, GPS, etcSoftware platform and applications
  • Useful for areas where low precision location is acceptableGood for FOD within wings and other assemblies (other RF e.g. 2.4GHz better than UWB for penetration through metal)Good for storage containers
  • All options already discussed apply in various casesGPS is a useful addition for some use cases, especially for larger areas (don’t need infrastructure)Need last known location for GPS (aircraft shadow, metal containers etc)
  • Common tag with UWB, presence, GPS very useful for full cycle of applicationsCommon infrastructure / software platformControl channel important for switching modes
