Testing of the Optical Bearing Beacon.

Abstract

The Optical Bearing Beacon is a prototype aid to navigation designed to provide the recreational boater with bearing information. The system is designed to provide bearings with reasonable accuracy using visual observations alone or with the aid of a stop watch. The bearing beacon uses a combination of a 190mm rotating beacon (1 RPM) and an omni-directional flashing beacon timed to produce a flash when the rotating beam is at some reference bearing. Measurement of the time interval between the omni-directional flash and the rotating beam flash and a simple calculation enable the user to obtain his bearing from the beacon. (Author)
