PILOTAGE WATERS VESSEL POSITION REPORTING SYSTEM
Vessel Position Reporting Systems based on radar would be difficult to implement in areas such as the Chesapeake Bay where several transmitters would have to be installed and maintained because of the Bay's size. An alternative configuration would be for the pilots to carry aboard a small Loran receiver. This receiver would contain an audio modulator that would send time delays back to the port captain via the normal radio communications channels now used. A demodulator on shore would be connected to a computer which would then maintain the track of each ship whose pilots carried aboard the Loran equipment. The system could be implemented slowly, so that there would be no large yearly capital outlay before its benefits could be realized. There would probably be no additional use of the RF spectrum, and there would be little technological risk in implementation.
