Two Brochures Available

On Sperry's Doppler

Speed, Navigation Systems

Two brochures on two distinct doppler systems have been pub- lished recently by Sperry Marine

Systems, Great Neck, N.Y.

One brochure concerns Sperry's

Doppler Speed Log which meas- ures speed and distance move- ments. The eight-page brochure describes the special features of the system—its components, in- stallation planning data, specifi- cations, and cabling. The system can be used with advanced radar, navigation, and computer sys- tems either for new building or retrofitting.

The second eight-page brochure provides similar technical infor- mation on Sperry's Doppler Nav- igation Sonar (DNS). The DNS is a high-technology navigation system designed for use as a bot- tom and or water reference nav- igator for submersibles and sur- face vessels. Used in conjunction with a compass or gyrocompass, it provides the operator with pri- mary navigation data including desired course set by the navi- gator, distances on course and across course, total speed, devi- ation from the desired course, al- titude above the ocean floor, and compass heading.
