IMU Inertial Measurement Unit

MTi 1-seriesInertial Measurement Units (IMUs) is a self-contained system that measures linear and angular motion usually with a triad of gyroscopes and triad of accelerometers. An IMU can either be gimballed or strapdown, outputting the integrating quantities of angular velocity and acceleration in the sensor/body frame. They are commonly referred to in literature as the rate-integrating gyroscopes and accelerometers.

Overview

IMU Inertial Measurement Unit

Extra sensors

The IMU products of Xsens also contain extra sensors, a 3D magnetometer (See MTi 1-series, MTi 10-series and MTi 100-series) and a static pressure sensor (MTi 100-series only).

Signal processing

In order to get accurate data from the IMU, it is necessary to have a good signal processing pipeline, optimized for the application. An accurate calibration of the MTi by Xsens provides a model of the internal sensors. When operational, the signal processing then consists of 3 blocks: sampling (at a high frequency), a carefully designed digital low pass filtering in order to prevent aliasing, application of the calibration model and Strapdown Integration (SDI) at 2 kHz. When this this entire signal processing pipeline is designed in a proper way, the data will have a high fidelity. Tests by Xsens confirm that this is the case for the MTi IMUs (contact Xsens for more information).

 

Applications

IMUs can serve as input for navigation systems (such as the MTi-G-700 GPS/INS) or included in stabilized platforms. Xsens can assist to determine which unit would best suit your needs.
