Examples of displayed digital and analogue communication

Underwater Comms System UT 3000

GeneralThe UT 3000 is the fi rst proven system to offer digital data transmission in addition to analogue voice com-munication. It is already installed in an increasing num-ber of submarines and surface ships worldwide.

Digital communication opens an infi nite number of new applications for a submarine at speed and depth. Fast exchange of tactical, operational and navigation data are only a few examples for the use of the system. Now also covered communication can be realized effectively. And there is much more to come, as automated identi-fi cation procedures.

Like its predecessors – the UT 12 and UT 2000 – the UT 3000 is designed, built and certifi ed to meet all relevant military specifi cations. This ensures safe and reliable communication even under harsh conditions.

The system setup and therefore installation is as easy as with the former sys-tems. All electronics are combined in the main unit with connectors to the trans-ducers and interfaces.

All features at your fi nger tipsA large display offers an unbeaten intuitive operation and variety of features as telephony, telegraphy, digital data transmission and reception, noise measure-ment, distance measurement and emergency mode. The online and offl ine BITE supports an uninterrupted availability of the system.

Up to four transducer groups are supported for directional or omni-directional transmission within the widest frequency range available on the market. On sur-face ships an optional outboard transducer enables communication even under adverse conditions.

Control and display unit SEB 34The control and display unit SEB 34 combines all electronics for transmission and reception as well as processing, power supply and control and display. The SEB 34 has been designed for maximum maintainability. Therefore it can be opened in seconds and the PCBs are arranged for easy access and replace-ment. This reduces the MTTR in most cases to a few minutes.

L-3 ELAC Nautik offers a stand-alone housing with and without shock mounts, but the unit may also be installed in an existing 19” rack.

TransducersTwo transducer versions are offered for surface ships and submarines. The cy-lindrical transducer array WB 54 is a compact array for surface ships with space limitations or for an easy refi t. It offers sector and omni-directional transmission and may be integrated in a sonar dome.

The planar transducer array WB 55 is the optimum choice for a distributed integration with maximum performance. Typically three or four of these arrays are integrated in the hull of a surface ship or submarine. A specially designed

dome for combining three or four WB 55 arrays is also available. Additionally the UT 12 / UT 2000 transducers TSE 4 and LSE 258 as well as the single type transdu-cers TSE 5 and TSE 7 are supported.

Pre-defi ned interfacesThe pre-defi ned interfaces enable exchange of all rele-vant data between the UT 3000 and the ship’s network. The keying interface makes sure that the UT 3000 does not interfere with other active or passive acoustic sen-sors on board of the surface ship or submarine.

An optional outboard transducer set for surface ships consists of a deck mounted connection box and a trans-ducer on a cable. Under adverse acoustic conditions the surface ship is still capable to communicate with the submarine by using this outboard transducer.

For higher output power requirements in excess of 1,000 W an enhanced version of the UT 3000 is offered on request as well.
