3DM-GX4-45? Product Datasheet - 1

LORD PRODUCT DATASHEET 3DM-GX4-45 (GPS/INS) GPS Aided Inertial Navigation System ™ The 3DM-GX4-45™ is a miniature, industrial-grade GPS Aided Inertial Navigation System (GPS/INS), utilizing the highest performance MEMS sensor technology. It combines a triaxial accelerometer, triaxial gyro, triaxial magnetometer, temperature sensors, pressure altimeter, and dual on-board processors running a sophisticated Extended Kalman Filter (EKF) to provide excellent position, velocity, and attitude estimates. Its form factor, temperature range, shock survivability, bias stability, vibration performance, low power and cost combine to make it the best performing INS/GPS in its class. Features & Benefits System Overview The 3DM-GX4-45™ offers a range of fully calibrated AHRS measurements including acceleration, angular rate, magnetic field, deltaTheta and deltaVelocity vectors. GPS measurements include LLH position, ECEF position and velocity, NED velocity, UTC time, GPS time, and SVI. Navigational data quantities from the Estimation Filter include GPS time, LLH position, NED velocity, quaternion, orientation matrix, Euler angles, gyro and accel bias, PVA uncertainties, linear acceleration, WGS84 gravity, pressure altitude and more. 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. • 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 position, velocity, & attitude estimations • high-speed sample rate & flexible data outputs • -40 °C to +85 °C ambient temperature range operation • high performance under vibration • high sensitivity GPS receiver Easiest to Use • smallest, lightest industrial GPS/INS available • simple integration supported by SDK and comprehensive MIP™ API Cost Effective • reduced cost and rapid time to market for customer’s applications The 3DM-GX4-45™ architecture has been designed to substantially eliminate common sources of error such as gain and offset errors induced by temperature changes and sensitivity to vibration. Gyro drift is extremely low and through a variety of estimation techniques it can approach near-tactical performance in many applications. Thanks to MIP™ data communications protocol, all 3DM-GX4™ are drop-in compatible with the 3DM-GX3® family of inertial sensors. The starter kit consists of the 3DM-GX4-45™ module, RS-232 or USB communication and power cable, GPS antenna, software, user manual, and quick start guide. 1.74 [44.3] • aggressive volume discount schedule • drop-in protocol compatibility with 3DM-GX3®, 3DM-RQ1™ families Accurate navigation and orientation under dynamic conditions in applications such as: • GPS-aided navigation system • camera stabilization • satellite, radar, and antenna pointing • platform stabilization, artificial horizon • unmanned vehicle navigation • reconnaissance, surveillance, and target acquisition • robotic control LORD MicroStrain SENSING SYSTEMS
