High Precision Applications

Primed for excellence, the MRU 5 is the optimal sensor for various motion

compensatory functions used in multi-beam echo sounders, offshore cranes,

hydroacoustic positioning systems, and dynamic motion monitoring on

offshore structures. Its unparalleled roll and pitch accuracy of 0.02° RMS

within a ±5° amplitude is proven and documented, ensuring reliable

performance on any surface vessel or subsea vehicle.

Advanced Sensor Technology and Configurability

Integrating three top-tier accelerometers with three premier Kongsberg

Seatex developed MEMS gyros of MRG type, the MRU 5 exhibits low noise

characteristics alongside exceptional bias stability and gain accuracy.

This high reliability is attributed to the use of solid-state sensors, which

circumvents any mechanical wear. Adding to its feature set, this unit comes

with specialized Windows-based configuration and data presentation software,

which allows for the precise definition of vector arms to the center of gravity

and two individually configurable monitoring points.

Enhanced Data Output and Complementary Algorithms

The MRU 5 is proficient in the output of critical motion-related variables,

such as roll, pitch, and yaw angles as well as angular rate vectors across

various adjustable frames. Furthermore, with the employment of the cutting-edge

PFreeHeave algorithm, it overcomes the perils of long swell conditions and is ideal

for applications that can utilize a delayed heave signal, commonly observed in

seabed mapping operations. External speed and heading inputs are also accepted

to augment the accuracy of heave, roll, and pitch under dynamic conditions.

The MRU 5 represents the pinnacle of marine motion sensing technology

– embodying a specially designed fifth-generation device that excels in

delivering high precision motion measurements within marine applications.

It stands out in its ability to offer highly accurate roll, pitch, and heave

measurements for the most demanding users.

Precision and Reliability

The MRU 5+ provides documented roll and pitch accuracy of 0.008°

and angle noise less than 0.002°. Every unit is delivered with an

individual calibration certificate documenting this accuracy. This is

made possible by use of accurate inertial sensors including three

rate gyros and linear accelerometers of excellent tactical navigation

grade performance. Very high reliability is achieved by using solid-state

sensors with no moving parts and the proven MRU electrical and

mechanical construction.

Advanced Motion Sensing Technology

The PFreeHeave algorithm uses past measurements to output a correct

and phase-free heave from MRU 5+. It has an advantage in long swell

conditions and for applications that can utilize a heave signal that is

delayed some minutes, typical for seabed mapping applications.

Additionally, a new MEMS based gyro is developed by Kongsberg Seatex

AS called MRG5 (Mru Rate Gyro) model 5. The MRG5 is optimized for use

in high-end applications. The MRU rate gyro combines very low noise,

excellent bias stability and outstanding gain accuracy and is the best

MEMS rate gyro available for maritime applications.

Ease of Integration and Application Flexibility

Interfacing the MRU 5+ to various sonar systems is made easy by including

data protocols for the most commonly used multibeam echo sounder systems

in the software. Using the configuration cable and the Windows version of the

configuration software, MRC+, a series of simple menu prompts allow the user

to choose the optimum configuration for his application. The MRU 5+ and the

MRC+ software are flexible and can accommodate a wide variety of application

types.

The MRU 5+ product is upgraded with the best MEMS based gyro

Easy to install

With the EA 600. you only need a standard data cable

between the transceiver unit(s) and the combined

display and processor. The transceiver(s) can either

be located close to the transducers, or in the vincinity

of the display. The powerful processing tasks required

does not take up any physical space any longer, as the

former Processor Unit has been fully integrated with

the LCD unit.

System software

The EA600 has a USB port in  front where a read/write

CD-ROM or DVD can be connected. Systen software

is supplied on a CD ready for installation, as are sub

sequent software releases. Data storage may also be

performed via this interface.
