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.
Gladiator Technologies is a leading designer and manufacturer of world class high performance MEMS Gyros & Accelerometers, Systems and Integrated GPS based on their over 100 years experiences.
The MRM analog IMU’s feature bias and scale factor modelling over the entire operating range, compensation for g sensitivity and misalignment as well as internal vibration isolation, precision alignment and environmental sealing for robust performance in hash applications.
Highlights:
- Better bias and lower noise;
- Low power, low voltage;
- Lightweight with small dimensions.

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.
