Introduction
3DM-GX3 -25 is a high-performance, miniature Attitude Heading Reference System (AHRS), utilizing MEMS sensor technology. It combines a triaxial accelerometer, triaxial gyro, triaxial magnetometer, temperature sensors, and an on-board processor running a sophisticated sensor fusion algorithm to provide static and dynamic orientation, and inertial measurements.
The system offers a range of output data quantities, including fully calibrated inertial measurements: acceleration, angular rate, and magnetic field; or deltaAngle & deltaVelocity vectors. It can also output computed orientation estimates: pitch, roll, and heading (yaw) or rotation matrix.
All quantities are fully temperature compensated and are mathematically aligned to an orthogonal coordinate system. The angular rate quantities are further corrected for G-sensitivity and scale factor non-linearity to third order.

The 3DM-GX3-25 AHRS is available with RS-232, USB 2.0 and TTL serial communication interfaces and is a member of the 3DM-GX3 family of inertial sensors.
Features & Benefits
- Smallest and lightest AHRS available on the market, with versions weighing only 11.5 grams.
- Fully temperature compensated over entire -40° to 75° C operational range.
- Calibrated for sensor misalignment, gyro G-sensitivity, and gyro scale factor non-linearity.
- Improved navigation under vibration, as sensors are sampled at 30 kHz and digitally filtered and scaled into physical units; coning and sculling integrals are computed at 1 kHz.
- Available with RS-232, USB 2.0 and TTL serial communication interfaces.
- User adjustable data rate, 1 to 1,000 Hz.
- Outputs Euler angles, rotation matrix, deltaAngle & deltaVelocity, acceleration angular rate and magnetic field.
Applications
- Inertial aiding of GPS.
- Location tracking of personnel.
