NORSUB 3000 SUBSEA: Motion Reference Units


Norsub MRUs use state-of-the-art MEMS technology and advanced sensor fusion algorithms. This results in accurate and reliable roll, pitch, yaw, surge, sway, heave and velocity measurements.With high performance in irregular motions, it is ideal for use in real sea conditions.


High performance 6 DoF motion sensor

Tailor made for subsea use

Comes in a waterproof titanium housing with ethernet and serial ports

Available in three different versions: 3000, 6000 and 9000 models

The performance is great also during horizontal accelerations and coupled motions.


Roll & Pitch:+/- 0.05° – RMS (dynamic)

Heave (real-time): 5.0 cm or 5.0 %; whichever is greater

Heading (optional):+/- 0.5° Magnetic heading

Rotation speed range:+/- 150°/s

Acceleration range: +/- 3 g –
