The development and successful sea test of an acoustic navigation system are described. The system is called Hydroways in the same general context as the word Airways is applied to air navigation. This acoustical beacon system requires at least two fixed bottom-mounted acoustic projectors for transmitting. The receiving equipment can be the ship's fathometer, which can provide a midchannel indication on a standard fathogram. This simple system can provide steering information similar to that obtainable from a visual range. The significant advantages are the all-weather capability and a substantial increase in useful range to seaward. Additional transmission coding and hardware could provide for multi-lane navigational control for ships simultaneously entering and leaving a major port.
