What are DOTs?

Dynamic Optical Tags (DOTs) will be small retro-reflecting optical tags that, via clandestine 2-way interrogation at up to 10km, provide unique identification and precision location for every tagged target in view.

DOTs Capabilities

  • As platform moves throughout a region the DOT can record location information (via GPS) as well as other data (imagery, audio, etc.) that can provide vital information and decrease target ambiguity.
  • DOTs are persistent despite harsh environmental conditions and length time periods between application and interrogation.
  • DOTs are interrogated by some asset (UAV, P-3, U-2, handheld, etc.).
  • DOTs fast optical link allow non-RF data exfiltration.
