LORD Microstrain GX4 Inertial Sensors

3DM-GX4-45The new 3DM-GX4 series of Inertial Measurement Unit (IMU) and Inertial Navigation systems, are designed to be drop in improved successors to the popular LORD MicroStrain 3DM-GX3 range. They are smaller, lighter and incorporate the latest in MEMS sensor technology, whilst including some extra features. The 3DM-GX4-25 is the general purpose model, with the -15 providing a lower cost choice without magnetometers, and the -45 providing enhanced features including GPS. These units have a USB or RS232 interface as standard. The 3DM-GX4-25TM offers a range of fully calibrated inertial measurements including acceleration, angular rate, magnetic field, deltaTheta and deltaVelocity vectors. It also outputs computed attitude 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 magnetic disturbances and 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-GX4-25TM 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. Applications for this device would include unmanned vehicle navigation, robotics, platform stabilisation, antenna and camera pointing, and personnel tracking. The 3DM-GX4-25 is initially sold as a starter kit consisting of an IMU module, RS-232 or USB communication and power cable, software, user manual, and quick start guide.
