Airborne system for operation in conjunction with a marker beacon

摘要

An airborne radio system upon receipt of mode and code radio signals from a marker beacon that it is seeking, queries the marker beacon as to its slant range and direction. Upon receipt of information on the slant range and direction the airborne system and/or its operator make a determination whether to initiate a radio signal that would activate a flare on the marker beacon. Upon actuation the flare is usable for visual and infrared homing.
