ROV – Remotely Operated Vehicles
Small-sized Inertial Sensors for Remotely Operated Vehicle
A Motion Sensor also called an AHRS, provides real-time roll, pitch, and heading information that is used to aid the operator when maneuvering an ROV.
Without the attitude information, it could be difficult for an operator to figure out if the ROV is well-positioned.

Tips
If you choose a model which relies on magnetometers for heading information, it will be sensitive to iron. The inertial sensor should be mounted far from engine(s) and other magnetic disturbances.
The SBG on-board calibration tool allows calibration in water. It ensures a precise heading in all orientation by taking into account the real environment where the ROV will be operated.
The Inertial Measurement Unit (IMU) outputs gyroscopes, accelerometers, and magnetometers raw data. The Attitude and Heading Reference System (AHRS) embeds an Extended Kalman Filter (EKF) to deliver orientation data, and the Inertial Navigation System (INS) additionally embeds a GNSS receiver for a filtered position in real-time.
