Products – Navigation Products

L3 Henschel's navigation products are used in our bridge and navigation systems and set new standards for functionality, operation and ergonomics. We provide custom design, manufacturing, qualification and factory acceptance testing, installation supervision, commissioning and crew training.

Our Ship Control Consoles are adaptable for all ship bridges and all conceivable ship operating requirements. L3's user-friendly technology improves safety, efficiency and operational economy through the seamless integration of all navigation sensors such as radar, ECDIS and GPS with shipboard control systems such as propulsion and steering.

We also provide individual components to complement bridge designs such as helm/lee helm consoles, chart stations, CO/XO and bridge wing stations, and indicating and ordering equipment including throttles, engine order telegraphs, ship's course indicators, pelorus, and rudder angle transmitters and indicators.

Display System

Ship's Data Display System

Equipment from L3 Henschel provides vital navigation and ship-control information in graphical and numerical formats on integrated flat-panel touchscreen displays.


NDDS

Navigation Data Distribution System (NDDS)

L3 Henschel offers a wide range of "middleware" equipment that allows existing systems to communicate with integrated networks. Our NavConverter and Input/Output Controllers (NC & IOC) and Computer Conversion Assemblies (CCA) interface with existing sensors and legacy systems to convert messages to compatible data formats and interfaces. L3 Henschel's data-conversion equipment allows users to provide a local area network for back-fit and forward-fit applications.

Consoles

Helm and Lee Helm Consoles

Bridge consoles

L3 Henschel bridge consoles provide vital navigation and ship control information to ship personnel to control steering and propulsion systems. Each console has the capability to receive and transmit vital navigation and ship control data via a dual-homed local area network (LAN). The consoles utilize a touch-control liquid crystal display (LCD) with Navigation Information Display System (NIDS) software. In the event of an Integrated Bridge System or LAN failure, the Helm Console has back-up capabilities to provide rudder orders to the Steering Control System using the Helm Wheel and AC analog signaling. The Helm Console also has an independent analog steering pump control and status panel. The Auto Pilot Operator Unit is located in the Helm Console. The Lee Helm Console is configured identical to the Helm Console with the exception of the Steering Unit Assembly (Helm Wheel) and Pump Status and Control Panel. The Throttle Unit is located in the Lee Helm Console. The Throttle Unit and Auto Pilot Operator Unit can be mounted in either the Helm or Lee Helm Console.

Workstations

ECDIS Workstations

L3 Henschel offers fully qualified ECDIS Workstations for every Navigation Task Station.

Our ECDIS Pedestal Workstation is a deck-mounted, freestanding ECDIS Thin Client Workstation intended for bridge installation. It provides a large, ECDIS-compatible 23" display and keyboard/trackball controls for the operator. The included ECDIS-compatible computer is designed for installation elsewhere using a high-performance KVM solution to support remote computer maintenance without creating disruptions on the bridge.

The L3 Henschel ECDIS Overhead Thin Client Display provides an ECDIS-compliant 23-inch display for overhead installation with remote keyboard/trackball controls to be located for easy operator access. The included ECDIS-compatible computer is designed for installation elsewhere using a high-performance KVM solution to support remote computer maintenance without creating disruptions on the bridge.

L3 Henschel also offers a bulkhead-mounted ECDIS computer/display all-in-one unit for locations where this is required. It provides all that is needed for an ECDIS workstation in a single, bulkhead-mounted unit.

Indicators

Indicating and Ordering Products:

COTS and custom-designed display and indicating equipment

L3 Henschel offers an extensive selection of both COTS and custom-designed display and indicating equipment. In addition, we have designed and manufactured a family of products including Ship's Course Indicators and Pelorus Stands, Engine Order Telegraphs, Rudder Angle Indicators and Transmitters, Integrated Digital Indicating Panels, Shaft Speed indicators, and RPM and Pitch Indicators.

Ship Course IndicatorsL3 Henschel Ship's Course Indicators are used on naval ships to display heading information received from the gyrocompass or navigational system, and offer exceptional reliability and durability. These units require little or no maintenance, have an excellent record of performance in demanding shipboard environments and have earned a reputation within the maritime community for dependable, trouble-free operation.

The Integrated Digital Ship's Course Indicator (SCI) Type B style consists of a case, cover and mounting configured for standard shipboard installations. The digital electronic internal subassembly and components have been adapted to utilize the standard cover and housing configuration of the Type B Indicator to provide a similar interface and operational requirements as standard Synchro-based equipment. The interface is similar in that the same heading display dials from the Synchro-based unit are used in the new digital electronic unit.

Shaft Speed Systems

Shaft Speed Indicator

L3 Henschel's Shaft Speed Indicator Systems are designed specifically for the exacting requirements of marine service. Each system provides a means of indicating the speed, direction of rotation and total number of revolutions of the main propeller shaft.


Rudder Indicators

Rudder Angle Indicator

(RAI)

The L3 Henschel Rudder Angle Indicator (RAI) is available with a waterproof cast aluminum housing, a synchro driven pointer and a 7-inch illuminated dial calibrated in rudder angle degrees. Two types are available: one to read 35 degrees right and left rudder; and one to read 45 degrees right and left rudder. Dials have a black background with white markings. Red dial illumination is controlled by a dimmer rheostat on the underside of the housing. A console-mounted version is also available.

(RAT)

Rudder Angle Transmitter

The L3 Henschel Rudder Angle Transmitter (RAT) is connected to a ship's rudder stock through a linkage furnished with the transmitter.

Rotation of the rudder causes rotation of the transmitter synchro that transmits to the indicators. The 10-1051 transmitter has a 4-to-1 internal gear ratio and is for use only with indicators having 35-degree dials. The transmitter has a 3-to-1 gear ratio and is for use only with indicators having 45-degree dials.


Telegraph

Engine Order Telegraph

(EOT)

The L3 Henschel Engine Order Telegraph (EOT) provides a means of communicating an order to change ship speed or direction from the bridge to the engine control room. The Engine Order Telegraph consists of a knob or lever (depending on the model) that can be moved to different speed positions for ahead and astern direction.

Indicator

Roll and Pitch Indicator

The L3 Henschel Roll and Pitch Indicator indicates the degree of roll and pitch. This is accomplished by information received from a gyrocompass and displayed on a dial calibrated in degrees. When a change in a ship's attitude, either roll or pitch, takes place, a change in signal appears in the ship's cable causing an AC error voltage output on the control transformer rotor that is applied to the amplifier input.
