What algorithms are used for motion measurement in underwater applications?
Norwegian Subsea utilizes advanced sensor fusion algorithms as the core technology for precise motion measurement in all our Motion Reference Units (MRUs), including those designed for underwater applications. These algorithms intelligently combine data streams from state-of-the-art MEMS (Micro-Electro-Mechanical Systems) sensors, primarily high-accuracy accelerometers and gyroscopes.
The primary function of these sophisticated algorithms is to process the raw sensor data and accurately compute the vessel's or equipment's motion across all six degrees of freedom (6DoF): Roll, Pitch, Yaw, Heave, Surge, and Sway. This comprehensive motion data is critical for the safety and efficiency of numerous underwater operations.
Our algorithms are rigorously developed and validated not just in laboratory settings, but crucially, under real-world sea conditions to ensure high performance, robustness, and reliability. This commitment ensures that Norwegian Subsea MRUs, such as the MRU Subsea and MRU Marine, deliver dependable motion data essential for demanding subsea environments.
