- W566813156 abstract "The Coast Guard is trying to minimize ship damage in the San Francisco Bay area by developing the San Francisco Experimental Vessel Traffic System (VTS), an all-weather complex consisting of radar, computers, and communications that will advise mariners of traffic conditions and warn them of danger. The system now being checked out during off hours, uses real-time automatic data processing to develop, analyze, and display information on ship traffic. The Coast Guard maintains surveillance by two complementary methods: radar and voluntary vessel-movement reports. Radar covers the San Francisco Bay and Pacific approach, but the Coast Guard must rely on vessel movement reports for the inland regions and as for south as Redwood City. Vessels passing designated sites in that region report to the control center and receive information on traffic conditions. One of the system's two 50-kilowatt X-band radars sweeps 15 miles seaward from Point Bonita. The second radar covers about 9 miles around Yerba Bunea Island. Six very-high-frequency channels are available for ship-to-shore communications, and all voice communications are automatically recorded on audio-tape units. Specific traffic situations, as viewed by the radar, can also be documented by wideband recording on a video-tape recorder." @default.
