LORD PRODUCT DATASHEET Miniature Attitude Heading Reference System The 3DM-GX3® -25-OEM 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. Its form factor is ideally suited for OEM applications. Features & Benefits • smallest, lightest industrial OEM AHRS available • simple integration supported by SDK and comprehensive API • precise attitude estimations • high-speed sample rate & flexible data outputs • high performance under vibration Cost Effective • reduced cost and rapid time to market for customer's • aggressive volume discount schedule Accurate navigation and orientation under dynamic conditions such as: • Unmanned Vehicle Navigation • Platform Stabilization, Artificial Horizon • Antenna and Camera Pointing • Health and Usage Monitoring of Vehicles • Reconnaissance, Surveillance, and Target Acquisition • Robotic Control • Personnel Tracking System Overview The 3DM-GX3® -25 OEM 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 OEM 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 OEM is initially sold as a starter kit consisting of an AHRS module, USB communication and power cable, software CD, user manual and quick start guide. The circuit board form-factor provides thru-holes for mounting on larger circuit assemblies and custom TTL communication and power cables can be user fabricated or purchased from the factory. triaxial gyros triaxial accels triaxial mags sensor signal calibration data user settable Silver Level Winner SENSING SYSTEMS
