3DM-GX2® Product Datasheet - 1

Technical Product Overview 3DM-GX2™ Gyro Enhanced Orientation Sensor Features & Benets 3DM-GX2™ is a high-performance gyro enhanced orientation sensor which utilizes miniature 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. • small, light-weight, low-power design ideal for size-sensitive applications including wearable devices 3DM-GX2™ oers a range of output data quantities from fully calibrated inertial measurements (acceleration, angular rate and magnetic eld or deltaAngle & deltaVelocity vectors) to computed orientation estimates (pitch & roll or rotation matrix). All quantities are fully temperature compensated and corrected for sensor misalignment. The angular rate quantities are further corrected for G-sensitivity and scale factor non-linearity to third order. • simultaneous sampling for improved time integration performance 3DM-GX2’s communications interface hardware is contained in a separable module, and can therefore be easily customized. Currently available interface modules include a wireless transceiver, USB 2.0, RS232 and RS422. An OEM version is available without the communications interface enabling the sensor to be integrated directly into a host system’s circuitboard, providing a very compact sensing solution. • fully temperature compensated over entire operational range • calibrated for sensor misalignment, gyro G-sensitivity, and gyro scale factor non-linearity • available with wireless and USB communication interfaces • user adjustable data rate (1 to 250Hz) and sensor bandwith (1 to 100Hz) • outputs include Euler angles, rotation matrix, deltaAngle & deltaVelocity, acceleration and angular rate vectors • inertial aiding INS and GPS, location tracking • unmanned vehicles, robotics – navigation, articial horizon • computer science, biomedical – animation, linkage free tracking/control • platform stabilization • antenna and camera pointing Micro Sensors.

3DM-GX2™ Inertial Measurement Unit and Vertical Gyro Specications The system 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. The use of six independent Delta-Sigma A/D converters (one for each sensor) ensures that all sensors are sampled simultaneously, and that the best possible time integration results are achieved. On-board coning and sculling compensation allows for use of lower data output rates while maintaining performance of a fast internal...
