LORD PRODUCT DATASHEET 3DM-GX4-15 Inertial Measurement Unit (IMU) The 3DM-GX4-15 ™ is a miniature high end industrial Inertial Measurement Unit (IMU), utilizing the highest performance MEMS sensor technology. It combines a triaxial accelerometer, triaxial gyro, temperature sensors, pressure altimeter and dual on-board processors running a sophisticated Adaptive Kalman Filter to provide excellent static and dynamic inclination estimates and inertial measurements. All of its features combine to make it the smallest and best performing IMU in its class. Features & Benefits System Overview The 3DM-GX4-15™ offers a range of fully calibrated inertial measurements including acceleration, angular rate, magnetic field, deltaTheta and deltaVelocity vectors. It also outputs computed inclination estimates including Euler angles (pitch, roll, and heading (yaw)), rotation matrix and quaternion. Uncertainty values and data-valid flags are available for all estimated outputs. Thanks to a sophisticated Adaptive Kalman Filter, the estimates are highly immune to linear motion. Bias tracking and sensor noise model options allow for fine tuning your application. All quantities are fully temperature compensated and are mathematically aligned to an orthogonal coordinate system. The 3DM-GX4-15™ architecture has been carefully designed to substantially eliminate common sources of error such as gain and offset errors induced by temperature changes and sensitivity to supply voltage variations. Gyro drift is extremely low and through a variety of estimation techniques it can approach near-tactical performance in many applications. Thanks to the MIP™ Protocol, the 3DM-GX4™ family is drop-in protocol compatible with the 3DM-GX3® and 3DM-RQ1™ families of inertial sensors. The 3DM-GX4-15™is initially sold as a starter kit consisting of an AHRS module, RS-232 or USB communication and power cable, software memory stick or CD, user manual, and quick start guide. • high performance gyros ∙ noise density: 0.005°/sec/√Hz ∙ drift: 10°/hr in-run bias stability ∙ g2 sensitivity: 0.003°/s/g2 rms • dedicated estimation processor for precise inclination estimations • high-speed sample rate & flexible data outputs • -40 °C to +85 °C ambient temperature range operation • high performance under vibration Easiest to Use • smallest, lightest industrial IMU/Inclinometer with Adaptive Kalman Filter available • simple integration supported by SDK and comprehensive MIP™ API Cost Effective • reduced cost and rapid time to market for customer’s applications • aggressive volume discount schedule • drop-in protocol compatibility with 3DM-GX3 , 3DM-RQ1™ families ® Applications Provides very stable and accurate attitude under dynamic conditions such as: • platform stabilization, artificial horizon • antenna and camera pointing • health and usage monitoring of vehicles • robotic control • rollover sensing LORD MicroStrain SENSING SYSTEMS
