KONGSBERG MRU2 is a roll and pitch motion sensor designed by KONGSBERG specifically for ships,offshore platforms,and underwater structures.It is mainly used for high-precision attitude measurement and motion compensation.The following is a comprehensive analysis of its core functions and technical features:

1、Core functions and design

High precision attitude measurement

Integrating two high-precision accelerometers and two MEMS angular rate gyroscopes,it can output static and dynamic roll angle,pitch angle,and angular rate vectors in real time,while monitoring surge and yaw acceleration.

Support horizontal acceleration center of gravity(CG)suppression,even when installed at high altitudes outside the ship(such as bridges),can eliminate the impact of horizontal acceleration on measurement accuracy through vector configuration,which is superior to traditional vertical reference devices.

Multi protocol communication and scalability

Provides RS-232,RS-422,and Ethernet(UDP)interfaces,supports IEEE 32-bit floating-point or scaled integer data transmission,and is compatible with ASCII NMEA 0183 protocol.

The output data can be distributed to multiple user terminals through two independently configured serial lines or Ethernet,meeting the requirements of complex system integration.

Compact and low-power design

Small size,light weight,low power consumption,suitable for installation on ships or marine equipment with limited space.

The protection level is not explicitly mentioned,but based on the universal design of Kongsberg marine equipment,it is speculated to have salt spray resistance,waterproof and dustproof capabilities.

2、Technical parameters

Category parameters

The measurement range of roll/pitch angle is limited(specific values need to refer to the model specifications)

Data rate 200 Hz

Output protocols RS-232,RS-422,Ethernet(UDP),NMEA 0183

Sensor type:accelerometer+MEMS gyroscope

Calibrate each device with a calibration certificate attached

3、Application scenarios

Ship Navigation and Dynamic Positioning

Provide real-time attitude data for dynamic positioning systems(DP)to enhance the stability and positioning accuracy of ships in complex sea conditions.

Ocean Engineering and Scientific Research

Used for direction and attitude compensation of underwater robots(ROVs)and autonomous underwater vehicles(AUVs)to ensure the safety of deep-sea operations.

High speed ship motion control

Integrated into the motion damping system,it suppresses the shaking of the ship in harsh sea conditions,improves passenger comfort and equipment operation stability.

Vertical pipe monitoring system

Monitor the movement status of offshore platform risers to prevent structural damage or leakage risks caused by posture changes.

4、Technical advantages

No mechanical wear and high reliability

Based on solid-state MEMS sensors,without rotating or mechanical components,it extends the service life and is suitable for long-term offshore operations.

Flexible installation and adaptability

Supports installation in a fixed direction on ships,suitable for applications with limited roll and pitch ranges;If full axis measurement is required,other MRU series models can be selected.

Software support

Provide configuration and data display software based on bbbbbbs to simplify parameter settings and data analysis processes.
