The 3DM-GX4 -25™ is a miniature industrial-grade attitude heading and reference system (AHRS) with integrated magnetometers, high noise immunity, and exceptional performance.
Product Highlights
- High performance integrated MEMS sensor technologyprovide direct and computed AHRS outputs in a small package.
- Triaxial accelerometer, gyroscope, magnetometer, temperature sensors, and a pressure altimeter achieve the best combination of measurement qualities.
- Dual on-board processors run a sophisticated AdaptiveKalman Filter (AKF) for excellent static and dynamic attitude estimates and inertial measurements.
Best in Class Performance
- Fully calibrated, temperature compensated, and mathematically aligned to an orthogonal coordinate system for highly accurate outputs
- Bias tracking, error estimation, threshold flags, and adaptive noise, magnetic, and gravitational field modeling allow for fine tuning to conditions in each application.
- High performance, low drift gyros with noise density of 0.005°/sec/√Hz and VRE of 0.001°/s/g2RMS
- Smallest and lightest industrial AHRS available
Ease of Use
- User-defined sensor-to-vehicle frame transformation
- Easy integration via comprehensive SDK
- Common protocol with the 3DM-GX3® and 3DM-RQ1-45™ sensor families for easy migration
Cost Effective
- Out-of-the box solution reduces development time.
- Volume discounts

Using MIP Monitor software, to reset the device to the factory defaults:
- Establish communication as normal with the sensor.
- Click Settings.
- Click Load Default Settings and a message box pops up.
- Click OK and the message box disappears.
- Click Settings again.
- Click Save Current Settings and a message box pops up.
- Click OK and the message box disappears.
This process does not erase any hard and soft iron calibration that may be on the device.
The Hard and Soft Iron Cal software we provide must be used to do that.
