THE HAZELTINE LANAC SYSTEM OF AIR AND MARINE NAVIGATION

Knox McIlwain and Charles J. Hirsch

Peer Reviewed

Abstract:	The Hazeltine Lanac system is a comprehensive navigation, anti-collision, traffi-control, and rescue system [1] utilizing low power pulse transmitters and receivers with associated meter and oscilloscope displays. The name Lanac is formed from the words “Llminar Navigation and Anti-Collision.” The system enables aircraft and surface vessels to navigate safely regardless of visibility conditions. It is a commercial outgrowth of the Identification, Friend or Foe ("IFF") systems [2] used for rapid identification of friendly ships and planes during the war, and as such it offers the automatic identification of all cooperating craft and beacons as one of its leading advantages. The system is in an advanced state of engineering development.
