The K-Bridge 26” Multi-functional Display combines the capabilities

of individual Radar, ECDIS and Conning stations in a single unit.

The 26” MFD is designed to be deployed in multiple locations

around the bridge. In each location it operates as a fully

standards-compliant Radar, ECDIS or Conning system; and at

any time its role can be instantly switched.

This gives the bridge crew maximum flexibility to adapt the

navigation operator stations to their immediate operating

requirements.

The facility for instantly shifting command of the autopilot

between operator stations contributes further to this flexibility.

FEATURES

• 26” (1920 x 1200 pixel) flat panel colour display (TFT)

• Manual and automatic radar target acquisition and tracking

• Vector charts displayed as underlay to the radar video (in the

Radar application)

• Radar video displayed as chart overlay (in the ECDIS

application)

• Conning information adapted to the current mode of operation

(track steering, docking, dynamic positioning)

• Three colour palettes (Day, Dusk, Night) for easy adaptation

of the display to ambient light conditions

• Remote control of the autopilot in Heading, Course and Track

modes by means of a dedicated operator panel

• Planning and monitoring of sailing routes

• Operator panel with analogue adjustment for gain and clutter

settings (in the Radar application)

• Sharing of charts, sailing routes and AIS targets with other

K-Bridge operator stations across a local area network

• ENC: S-63 and S-57 Edition 3 (official charts)

• Vector charts: AVCS (UKHO), Navtor, Primar, Jeppesen/C

Map

• Raster charts (in the ECDIS application): ARCS (UKHO) or

Seafarer (AHO)

Components

The basic EM 2040P has three units: A sonar head, a

processing unit and a workstation.

The sonar head has bumpers in the corners of the face of the

transducer to protect the it if it is placed on deck, and it has

carrying handles on the sides.

The EM 2040P can be delivered with the standard processing

unit or with a splash proof (24 VDC) portable processing unit.

For completeness, data input from a motion sensor and a

positioning system is required. As is the sound speed profile

of the water column between the transducer and the bottom.

Sound speed at the transducer depth is an optional input.

Optionally, the sonar head can be delivered with mounts for

motion sensor and sound speed sensor, factory aligned for ease

of mounting.

All electronics are contained in the sonar head which is

interfaced to the processing unit via GBit Ethernet. The

processing unit also supplies 48 V power via the same cable.

Operator control, data quality inspection and data storage is

handled by the hydrographic workstation running SIS software

or by 3rd party software.

FEATURES

• High resolution

• Wide frequency range

• FM chirp

• Roll, pitch and yaw stabilisation

• Nearfield focusing – both on transmit and receive

• Short pulse lengths, large bandwidth

• Water column display

• Seabed image

• Depth rated to 30 m

• Easy to install

Options:

• Water column logging

• Extra detections

• Dual swath

The EM 2040P is a shallow water multibeam echo sounder based

on the EM 2040 technology, an ideal tool for any high resolution

mapping and inspection application.

The receiver and transmitter are integrated in a common sonar

head. The system fulfils, and even surpasses, the IHO-S44 special

order and the more stringent LINZ specification.

Key facts

The operating frequency range is from 200 to 400 kHz. The

operator can on the fly choose the best operating frequency for

the application: 300 kHz for near bottom, 200 kHz for deeper

waters and 400 kHz for very high resolution inspection. Due

to the very large operating bandwidth available, the system

will have an output sample rate up to 60 kHz. The system can

effectively operate with very short pulse lengths. The shortest

pulse is 14 microseconds, which gives a raw range resolution

(cτ/2) of 10.5 mm.

By utilizing both CW and FM chirp pulses, the system can

achieve a much longer range capability with a high resolution.

The maximum depth range in cold ocean water is 600 m at 200

kHz with a swath with up to 830 m.

The angular coverage for the 200 and 300 kHz is 140 degrees,

allowing coverage of 5.5 times water depth. For the 400 kHz

mode the angular coverage is 120 degrees.

As an option the EM 2040P can be delivered with the dual

swath capability, allowing a sufficient sounding density along

track at a high vessel speed.

Functional description

Figure 1 shows the arrangement of the SENTRY Wireless

Temperature Monitoring System installed on a 4-stroke diesel

engine.

• A wireless sensor is fitted to the moving part (e.g. the

connecting rod of an engine)

• A Stationary Antenna is fitted to a bracket inside each cylinder

compartment in a position so that the sensor will pass nearby as

the engine runs.

• Coaxial cables connect the stationary antennas with the

Signal Processing Unit fitted outside. The bulkhead penetration

is made by use of a special, high IP-grade cable gland in which

the coaxial cable shield is terminated to ground.

• The Signal Processing Unit calculates the temperature and

transmits the result to the engine control system.

The SENTRY GB-300 system is based on Surface Accustic

Wave (SAW) -and radar technology. The sensors are passive,

have no battery and are in no need of an external power source.

The KONGSBERG SENTRY GB-300 is a unique product developed for

temperature monitoring of crank pin/crosshead bearings in diesel

engines and other rotating machinery.

Features

•  Fast and reliable temperature response.

•  By providing an early warning the consequence of o bearing

seizure is reduced to a minimum.

The MGC R4 COMPASS system is IMO type approved as a

gyro compass for navigation purposes for use together 

with a heading and bearing repeater. Very high reliability

is achieved by using Ring Laser Gyros with no rotational

or mechanical wear-out parts.

Function

The MGC is a strap-down based gyro compass

including three Ring Laser Gyros (RLG) and three linear

accelerometers. The system can operate in Attitude and

Heading Reference System (AHRS) mode and Inertial

Navigation mode. In the AHRS mode input of speed

and latitude data (VBW/VTG and GGA/GLL) is required.

External time input is also required (ZDA). In this mode

the system will output heading, roll, pitch and heave. In

the Inertial Navigation mode input of latitude, longitude,

height and time (GGA and ZDA) and PPS from a GNSS

receiver is required. In this mode the product will output

heading, roll, pitch, heave and position.

The system is delivered with configuration software.

In this software the user selects output formats on the

different communication lines in addition to other

configuration purposes.

Typical applications

The system can be operated as an inertial navigation

system as well as a gyro compass with output of position

and heading. Linear position and velocity measurements

can then be output in up to four different points on the

vessel.

Digital I/O protocols

MGC data is available through both Ethernet interface and

serial lines enabling easy distribution of data to multiple

users on board the vessel. Output protocols for commonly

used equipment are available on five individually

configurable serial lines and five Ethernet/UDP ports.

FEATURES

• 0.008° roll and pitch accuracy

• 0.02° heading accuracy GNSS aided

• No rotational or mechanical wear-out parts

• Outputs on RS-422 and Ethernet

• High output data rate (200 Hz).
