Motion Reference Modules (MRM)
Motion Reference Modules (MRMs) are single or multi-axis sensors that designed to measure the six possible degrees of freedom, i.e. roll, pitch, yaw, surge, heave, and sway motions. Motion reference modules are widely used in high speed craft motion control and damping systems, vessel motion monitoring, heave compensation of offshore cranes, ocean wave measurement and etc.

The essential components of a solid-state MRM are three linear acceleration and three angular rate sensors. These six sensors measure motions relative to a central point. Though MRM have very small dimensions, there are different operating principles on which the linear acceleration and angular rate sensors can be based, and the accuracy of the measurement depends on the placement of the system that is suitable for specific applications.
