The LORD Sensing 3DM-CV5 family of lower cost miniature industrial-grade board-level inertial sensors provides a wide range of triaxial inertial measurements and computed attitude and navigation solutions.

In all models, the Inertial Measurement Unit (IMU) includes direct measurement of acceleration and angular rate. In models that include computed outputs, sensor measurements are processed through an auto-adaptive estimation filter algorithm to produce high accuracy computed outputs under dynamic conditions. Compensation options include automatic compensation for magnetic anomalies, gyro and accelerometer noise, and noise effects. The computed outputs vary between models and can include pitch, roll, yaw, a complete attitude and heading reference solution (AHRS), or a complete position, as well as integrated GNSS outputs. All sensors are fully temperature-compensated and calibrated over the operating temperature. The use of Micro-Electro-Mechanical System (MEMS) technology allows for highly accurate, small, light-weight devices.

The LORD Sensing MIP Monitor  software can be used for device configuration, live data monitoring, and recording. Alternatively, the  MIP Data Communications Protocol is available for development of custom interfaces and easy OEM integration.
