Abstract:	THIS PAPER DISCUSSES Acoustic Doppler Navigators, covering briefly the principles of operation, some of the factors affecting the accuracy of Doppler sensors, and certain of the pertinent parameters of Doppler devices now in existence. Fig.1 shows a chart on which was automatically recorded the path of Raytheon’s test boat, ALAN, as she traveled from Newport, Rhode Island to Providence, Rhode Island. The trip spans a round-trip distance of 44 miles (82 km). As may be seen, the accuracy of the plot was sufficient to indicated entry into narrow channels at both the midpoint and the end of the trip. The track was produced immediately as the ship moved along. Although the ship was not directly guided in this case by the Doppler navigator, the continuous real-time position information provided by the Doppler navigator can and has been used to provide conning information. This plot was made by the progenitor of the navigator equipment which has been supplied to the United States Navy. Plotting was accomplished in real time so the position of the ship was indicated on the charts at all times. No reference to external facilities was made during the trip---this equipment is entirely self-contained.
