Two Brochures Available On Sperry's Doppler Speed, Navigation Systems

Two brochures on two distinct doppler systems have been published recently by Sperry Marine Systems, Great Neck, N.Y.

One brochure concerns Sperry's Doppler Speed Log which measures speed and distance movements.

The eight-page brochure describes the special features of the system—its components, installation planning data, specifications, and cabling. The system can be used with advanced radar, navigation, and computer systems either for new building or retrofitting.

The second eight-page brochure provides similar technical information on Sperry's Doppler Navigation Sonar (DNS). The DNS is a high-technology navigation system designed for use as a bottom and or water reference navigator for submersibles and surface vessels. Used in conjunction with a compass or gyrocompass, it provides the operator with primary navigation data including desired course set by the navigator, distances on course and across course, total speed, deviation from the desired course, altitude above the ocean floor, and compass heading.
