How is real-time data analysis performed with motion reference units?
Norwegian Subsea Motion Reference Units (MRUs) are designed to provide high-accuracy, real-time motion data crucial for monitoring, control or instrument compensation in demanding marine and subsea applications. Our MRUs utilize state-of-the-art MEMS sensors combined with advanced sensor fusion algorithms to continuously measure Roll, Pitch, Yaw, Heave, Surge, and Sway (6 Degrees of Freedom - 6DoF).
The core function enabling real-time analysis is the MRU's internal processing capability. Raw sensor readings are processed onboard using sophisticated algorithms to calculate precise orientation and motion data with minimal latency. This processed data is then immediately available for output.
This real-time motion data is transmitted from the MRU to external systems for analysis and decision-making. Norwegian Subsea MRUs facilitate seamless integration by offering versatile connectivity options, including Ethernet and serial ports (RS-232/RS-485), and supporting a wide range of standard industrial communication protocols like UDP, Modbus TCP, Ethernet/IP, NMEA, as well as custom ASCII or binary formats.
Therefore, while the MRU performs the critical task of accurately measuring and outputting motion data in real-time, the subsequent analysis of this data is typically performed by the connected client system, which relies on the high-quality, low-latency data stream provided by our reliable MRUs.
