Raytheon Introduces Doppler Speed Log A versatile new sonar navigation product for commercial marine use has been introduced by Raytheon Company. Called the Fairway Dop- pler Speed Log, it provides precise speed logging to 1,000-foot depths— 400 feet deeper than the 600-foot depth that has previously limited bot- tom-tracking instruments. The Fairway Doppler Speed Log gives accuracy of one-half of one percent of the speed range of 40 knots and provides a distance read- out with resolution of one-tenth of a nautical mile. Depth indication and selectable depth alarm are offered as built-in optional extras. The system is all solid state and utilizes the latest in digital processing technology to provide accurate main- tenance-free operation. The bridge control unit features an easy-to-read digital display that can be cabinet mounted, attached to a bulkhead or hung from the overhead. Analog and digital repeater displays can be posi- tioned throughout the ship as de- sired. Speed and depth-data inputs can also be furnished to true-motion ra- dars, collision-avoidance displays and electronic navigators. The product utilizers dual narrow beams from a transducer array that is mounted eas- ily in a gate valve or sea chest. Additional information and litera- ture on the Fairway Digital Doppler Sonar Speed Log can be obtained from the marketing manager, Ray- theon Maritime Systems, Portsmouth, R.I. 02871.
