Product Specifications

Technical details and manufacturing context for Inertial Measurement Unit (IMU)

Definition
The Inertial Measurement Unit (IMU) is a core component of a Motion Reference Unit (MRU). It provides the raw motion data (linear acceleration and angular velocity) that the MRU's processing unit uses to compute the vessel's or platform's precise heave, surge, sway, roll, pitch, and yaw motions. It is the primary sensor package for motion detection within the MRU system.
Working Principle
It operates by using micro-electromechanical systems (MEMS) or fiber-optic gyroscopes (FOG) to measure angular velocity and MEMS accelerometers to measure linear acceleration. These sensors provide continuous analog or digital outputs proportional to the motion experienced. The data from these sensors is typically fused within the IMU or by the MRU's central processor using algorithms to determine orientation and motion.
Common Materials
Silicon (for MEMS sensors), Fiber Optic Cable (for FOG), Electronic Circuit Board, Protective Housing (often aluminum or stainless steel)
