$2.34-Million Navy

Contract Awarded To

Sperry Division

The U.S. Naval Sea Systems

Command has awarded the Sperry

Division of Sperry Corporation a $2.34-million contract to develop and produce an advanced velocity measuring system for Navy sub- marines.

These new systems, called Dop- pler Sonar Velocity Logs (DSVL), will be produced and delivered to the Navy in 1981 for testing. Ve- locity logs are used to measure ship's speed through water as well as the ship's speed over the sea bottom, and to provide data for navigation and fire control solutions.

The Sperry DSVL will use ad- vanced doppler sonar coupled with data enhancement to provide high- er accuracy and greater reliabil- ity than existing electromagnetic and pitometer log equipment, which is now used by the Navy to measure velocity. The DSVL will provide velocity measure- ment in all three axes of the vessel.

Morton J. Howard, Sperry's marketing manager for the proj- ect, said that Sperry plans to adapt this new velocity log for use on military surface ships.

Master Clock System

A marine digital master clock system that displays master and local time is now available from

National Marine Service for all vessels. Master time can be Green- wich Mean or home port time, while local time is ship's time.

The system also has an auto- matic digital calendar that pro- vides serial time information for data and bell logging or other processing equipment. Microproc- essor-based, solid-state electron- ics assure that the system is maintenance-free. And because of a locking panel, the master clock system is free from unauthorized time changes. The digital display automatically dims at night ac- cording to the pre-set intensity level of the dimmer control.

An unlimited number of remote units can be installed up to 2,000 feet distant. The clock system comes in free-standing or flush- mounted models. And should a ship's power fail, battery backup powers the system for 24 hours.
