NEW NAVIGATION AID
Television Direction Finder For Ships
Ships at sea will ibe 'better able to get their bearings, with a minimum of interference from electrical storms and overlapping radio stations, when commercial use is made of a new directionfinder developed and now .being perfected at the National Research Council laboratories in Ottawa.
The direction-finder depends on the eye rather than the ear. It utilizes a cathode ray tube similar to that for television reception, says the "Christian Science Monitor.”
The device visually indicates the exact direction of the sending land station by a streak of fluorescent light. Around the tube face is a dial calibrated in 360 degrees like a compass, which enables the operator to take the bearings of a couple of radio stations in a few seconds, considerably faster than by the aural method. In an. electrical storm, this finger of light becomes merely momentarily fuzzy ns static is discharged. If two or three stations are overlapping, they will usually be registered as two or three separate and distinct light fingers, not interfering with each other as in radio reception.
