Which IMU offers the best operational stability?
All Norwegian Subsea Motion Reference Units (MRUs) are engineered for exceptional operational stability. This is achieved through the integration of advanced sensor fusion algorithms, state-of-the-art MEMS sensor technology, and rigorous validation processes conducted in real-world sea conditions, ensuring reliable and accurate motion data.
The optimal MRU choice depends on the specific operational environment rather than inherent differences in core stability. The MRU Compact (IP65) is ideal for protected indoor installations, the MRU Marine (IP68/50m) suits deck mounting and shallow water use, the MRU Subsea (6000m Titanium) is designed for deep-water applications, and the MRU Ex provides certified safety for hazardous areas. Each model delivers robust performance within its designated environment.
Our MRUs demonstrate excellent long-term stability, supported by standard 4-year calibration certificates, minimizing the need for frequent recalibration in most applications. This reliability also makes them highly suitable and cost-effective for retrofitting older systems, often as a direct drop-in replacement without requiring system recalibration.
