2.6 Inertia Measurement Unit
The motion sensor suite in the Inertia Measurement Unit (IMU) contains rate sensors that measure the angular movements of the vessel and accelerometers that measure the vertical and lateral boat movement. These signals are communicated to the ECM on a CAN bus connection inside the Seakeeper’s wiring harness.
