Navigate the sky with confidence.

Navigating the sky in today’s complex world of mixed civilian and military airspace, coupled with ever-increasing air traffic and evolving aerospace technologies requires that global military air traffic controllers and air defenders have a reliable, low-cost capability to swiftly
and effectively distinguish friend from foe. Telephonics’ Passive Detection and Reporting System (PDRS) passively receives signals providing an improved air surveillance picture, to meet the needs of today’s air traffic controller and air defenders.

Why choose passive air surveillance?

Passive air surveillance provides several benefits to air control and air defense operators including:

  • Situational awareness at the lowest operational cost
  • No interference with other RF systems
  • Non-radiating, stealthy detection and surveillance
  • Cueing of Mode S interrogators eliminating the need for Mode S All-Calls

PDRS addresses new FAA, NATO and Eurocontrol mandates by passively receiving Mode S/ADS-B and Mode 5 Level 2 squitters as well as 978 UAT signals.
