Miniature Attitude Heading Reference System Data Sheet The 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 Features & Benefits smallest and lightest AHRS available on the market fully temperature compensated over operational range calibrated for sensor misalignment, gyro g-sensitivity, and gyro scale factor non-linearity to third order improved performance under vibration, as sensors are sampled at 30 kHz and digitally filtered and scaled into physical units; coning and sculling integrals are computed at complementary filter eliminates gyro drift in AHRS output output includes Euler angles, rotation matrix, deltaTheta, deltaVelocity, quaternion, acceleration, angular rate and magnetic field versions available from 1.7 g to 50 g and 507s to 12007s rugged aluminum enclosure with precision mounting holes ROHS compliant location tracking of vehicles or personnel unmanned vehicle navigation platform stabilization, artificial horizon antenna, satellite and camera pointing biomechanics, biomedical animation automotive, marine, military heavy equipment, container handling virtual reality, computer science reconnaissance, surveillance and target acquisition system MicroStrain* Little Sensors, Product Overview The 3DM-GX3® -25 offers a range of fully calibrated inertial measurements including acceleration, angular rate, magnetic field, deltaTheta and deltaVelocity vectors. It can also output computed orientation estimates including Euler angles (pitch, roll, and heading (yaw)), rotation matrix and quaternion. 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 architecture has been carefully designed to substantially eliminate common sources of error such as hysteresis induced by temperature changes and sensitivity to supply voltage variations. Gyro drift is eliminated in AHRS mode by referencing magnetic North and Earth's gravity and compensating for gyro bias. On-board coning and sculling compensation allows for use of lower data output rates while maintaining performance of a fast internal sampling rate. The 3DM-GX3® -25 is initially sold as a starter kit consisting of an AHRS module, RS-232 or USB communication and power cable, software CD, user manual, and quick start guide. calibration data user settable Silver Level Winner
