The LORD Sensing 3DM-GX5 family of high-performance industrial grade inertial sensors provides a wide range of triaxial inertial measurements and computed attitude and navigation solutions.

The  3DM-GX5-25 is the smallest and lightest industrial AHRS with an Adaptive Kalman Filter available. It features a triaxial accelerometer, gyroscope, magnetometer, and temperature sensors to achieve the optimum combination of measurement qualities. Additionally, the dual on-board processors run a new Auto-Adaptive Extended Kalman Filter (EKF) for outstanding dynamic attitude estimates, making it ideal for a wide range of applications, including platform stabilization and vehicle health and usage monitoring.

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.

Best in Class Performance

  • Bias tracking, error estimation, threshold flags, and adaptive noise modeling allow for fine tuning to conditions in each application
  • Accelerometer noise as low as 25 ug/√Hz
  • Smallest and lightest industrial AHRS with Adaptive Kalman Filter available

Ease of Use

  • Automatic magnetometer calibration and anomaly rejection eliminates the need for field calibration
  • Automatically compensates for vehicle noise and vibration
  • Easy integration via comprehensive and fully backwards-compatible communication protocol
  • Common protocol between 3DM-GX3, GX4, RQ1, GQ4, and GX5 inertial sensor families for easy migration

Cost Effective

  • Out-of-the box solution reduces development time
  • Volume discounts
