MRU 2. the fifth generation roll and pitch motion sensor, is designed for high accuracy roll and pitch measurements in marine applications.

This unit, which must be fixed in a specific direction relative to the ship, is particularly suited for applications with a limited roll and pitch range.

It is essential for many uses such as offshore riser monitoring systems, dynamic positioning systems, telecommunication antenna systems, and motion damping systems on high-speed crafts.

Advanced Sensing Functionality

Boasting two highly precise accelerometers and MEMS angular rate gyros, MRU 2 is distinguished for its reliability that stems from solid state sensors without rotational or mechanical parts prone to wear.

MRU 2

It comes with Windows-based software for configuration and data presentation. When positioned high up in a ship, such as on the bridge, the MRU 2 outperforms inclinometers and standard Vertical Reference Units due to its capability to suppress horizontal accelerations affecting roll and pitch measurements.

Operational Design and Output

The MRU 2 outputs both static and dynamic roll and pitch angles, along with corresponding angular rate vectors.

Furthermore, it delivers surge and sway accelerations. Offering digital I/O protocols,

MRU data can be accessed via Ethernet interface and serial lines which enable the easy distribution of data to multiple users on board.

The Kongsberg MRU-M-SU1 (often referred to as the MRU S) is a high-precision Motion Reference Unit specifically engineered for marine applications that require real-time compensation for vessel movement.

While it belongs to the broader “MRU” family used in Dynamic Positioning (DP), it is most commonly integrated with fish-finding sonars, multibeam echosounders, and hydrographic survey equipment to stabilize the display and data during rough sea conditions.1

Technical Specifications

The MRU-M-SU1 (MRU S) utilizes solid-state MEMS (Micro-Electro-Mechanical Systems) technology, meaning it has no moving parts and requires no scheduled mechanical maintenance.2

Feature    Specification

Model    MRU-M-SU1 (Part of the MRU S series)

Roll & Pitch Accuracy    0.1° RMS (Dynamic)

Heave Accuracy    5 cm or 5% (whichever is highest)

Angular Orientation Range    $\pm 45^\circ$

Output Data Rate    Up to 200 Hz

Interfaces    Ethernet (TCP/IP, UDP), RS-232. and RS-422

Power Supply    10 to 36 VDC

Housing Material    Anodized Aluminum

Key Capabilities

Motion Compensation: It calculates real-time Roll, Pitch, and Heave.3 This data allows sonar systems to “cancel out” the movement of the boat, ensuring that a school of fish or a seabed feature stays in the same position on the screen even as the boat rocks.

Lever Arm Compensation: The unit can be configured with “lever arms,” allowing it to calculate the exact motion at a remote point (like the sonar transducer head) even if the MRU is mounted elsewhere in the hull.

Solid-State Reliability: Because it uses MEMS sensors rather than traditional mechanical gyros, it is highly resistant to vibration and has a significantly higher MTBF (Mean Time Between Failures).4

Easy Integration: It supports common marine protocols, including NMEA 0183. and can be configured via Kongsberg’s Windows-based “MRC” software.5

Common Use Cases

Fishery Sonars: Vital for high-end sonar systems where wave motion would otherwise cause “smearing” or jumping on the display.6

Hydrographic Surveying: Used with single-beam or multibeam echosounders to correct depth soundings for vessel heave.

Offshore Cranes: Providing heave data to active heave compensation (AHC) systems to keep loads steady during transfer.7

Maintenance & Service Tip

Recalibration: Kongsberg recommends factory recalibration for the MRU S series every 2 years to maintain its specified static accuracy. If your system is reporting a “Sensor Health” warning or if you notice a

Specialized I/O: Can be fitted with expansion cards for CAN bus or Profibus communication depending on the vessel’s specific configuration.5

System Applications

You will find the MP 5810 acting as the “brain” for the following systems:

K-Chief 600 / 700: Alarm Monitoring & Control System (AMS).

K-Pos: Dynamic Positioning OS.

K-Bridge / SIS: Hydrographic Work Stations and Navigation Integrators.6

AutoChief: Main Engine Remote Control System.

Maintenance Tips

SSD Reliability: Because these units use SSDs, they are much more resistant to ship vibration than the older MP7900 units. However, if the system becomes sluggish, check the SSD health as they have a finite write-cycle life in data-heavy automation logs.

CMOS Battery: If the computer fails to boot or loses the system time (which can desync it from the Redundant Net), the CR2032 coin cell battery on the motherboard likely needs replacement.

Dust Accumulation: Despite its “hardened” design, the oversized cooling system can pull in dust from the console. Annual internal cleaning is recommended to prevent CPU throttling.

MD-224 (Moxa variant): In some newer Kongsberg setups, you may find rebranded Moxa units which serve a similar purpose but use different internal drivers.

Maintenance Note

If you are experiencing a “No Signal” or Black Screen issue:

Check the Power Supply: If the status LED is completely off, the internal AC/DC power module may have failed (a common issue in older units).

Backlight Failure: If you can see an image faintly with a flashlight but the screen is dark, the LED driver or backlight strip is likely at fault.

Control Lock: Sometimes the front panel buttons are “locked” via the OSD (On-Screen Display) menu to prevent accidental dimming; this can be unlocked via a specific key combination (usually holding ‘Menu’ and ‘Select’).
