$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 submarines.

These new systems, called Doppler Sonar Velocity Logs (DSVL), will be produced and delivered to the Navy in 1981 for testing. Velocity 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 advanced doppler sonar coupled with data enhancement to provide higher accuracy and greater reliability than existing electromagnetic and pitometer log equipment, which is now used by the Navy to measure velocity. The DSVL will provide velocity measurement in all three axes of the vessel.

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