Lord MicroStrain 3DM-GX4-45 GPS-Aided Inertial Navigation System

Description

These units have been used. Not sure how many times but they do function normally.
The
3DM-GX4-45™
is a miniature industrial-grade all-in-one navigation solution with integrated GPS and magnetometers, high noise immunity, and exceptional performance.
Product Highlights
High performance integrated GPS receiver and MEMS sensor technology provide direct and computed PVA outputs in a small package.
Triaxial accelerometer, gyroscope, magnetometer, temperature sensors, and a pressure altimeter achieve the best combination of measurement qualities.
Dual on-board processors run a sophisticated Extended Kalman Filter (EKF) for excellent position, velocity, and attitude estimates.
Best in Class Performance
Fully calibrated, temperature compensated, and mathematically aligned to an orthogonal coordinate system for highly accurate outputs
Bias tracking, error estimation, threshold flags, and adaptive noise, magnetic, and gravitational field modeling allow for fine tuning to conditions in each application.
High performance, low drift gyros with noise density of 0.005°/sec/√Hz and VRE of 0.001°/s/g2RMS
Smallest and lightest industrial GPS/INS available
Ease of Use
User-defined sensor-to-vehicle frame transformation
Easy integration via comprehensive SDK
Common protocol with the 3DM-GX3® and 3DM-RQ1-45™ sensor families for easy migration
