KONGSBERG MRU-E-JB1 SEATEX MRU MOTION REFERENCE UNIT

KONGSBERG SEATEX MRU-E-JB1 Motion Reference Unit
I. Basic Identification Information
Full model: MRU-E-JB1 (SEATEX series, which was acquired by Kongsberg and incorporated into the Kongsberg Marine Products line)
Equipment Full Name: Motion Reference Unit – Ship Attitude Motion Reference Unit
Location: High-precision inertial attitude sensor, specifically designed for DP positioning, course control, wave compensation, ROV/AUV navigation, and marine surveying, providing six-axis attitude data including roll, pitch, heave, yaw/heading, angular velocity, and acceleration
JB1 Meaning: Integrated wiring box version, factory pre-installed sealed wiring terminal box, directly compatible with ship cabin/deck installation wiring, different from the bare board MRU-E basic model

Core Measurement Performance Indicators
1. Attitude Angle Accuracy
Roll / Pitch: ±0.01° static accuracy, dynamic ±0.03°
Yaw/Heading: ±0.1° (with built-in rate gyroscope)
2. Heave (Vertical Displacement, DP core parameter)
Measurement Range: ±10 m
Accuracy: ±0.05 m within the range, stable filtering output under high-frequency waves
3. Angular Velocity and Acceleration
Three-axis Angular Velocity Range: ±150 °/s
Three-axis Acceleration Range: ±2 g
4. Filtering Characteristics
Built-in multi-level adaptive wave filtering algorithm, software switchable DP mode, mapping mode, lifting compensation mode, automatically filters out ship high-frequency wave jitter, and outputs smooth and stable attitude values to K-Pos DP master control

Hardware Sensing Architecture
Six-axis MEMS Inertial Sensing Array: 3-axis Accelerometer + 3-axis Gyroscope
Optional external GPS / Compass input for combined navigation calibration, long-term zero drift suppression
JB1 Integrated Sealed Wiring Box: Internal terminals divided into power, communication, and shielded ground, one-piece waterproof and dustproof molding, on-site wiring does not require additional waterproof box
