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
Cost Effective
- Out-of-the box solution reduces development time.
- Volume discounts
