The MicroStrain 3DM is a high-accuracy attitude heading reference system that utilizes MEMS sensor technology. The sensor combines a triaxial accelerometer, gyro and magnetometer, temperature sensors and on-board processor.  Inertial measurement data is typically incorporated into pose calculations to improve localization estimation.


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
