3DM-GX3™-25 is a high-performance miniature Attitude Heading Reference System, 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.

It offers a range of output data quantities from fully calibrated inertial measurements (acceleration, angular rate and magnetic field or deltaAngle & deltaVelocity vectors) to computed orientation estimates, including 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 and 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 1000 Hz

Outputs Euler angles, rotation matrix, deltaAngle & deltaVelocity, acceleration angular rate and magnetic field
