3DM-GX4-15

Discontinued

The 3DM-GX4-15™  is a miniature industrial-grade inertial measurement unit (IMU) and vertical reference unit (VRU) with high noise immunity, and exceptional performance.

Product Highlights

  • High performance integrated MEMS sensor technology provide direct and computed IMU and VRU outputs in a small package.
  • Triaxial accelerometer, gyroscope, temperature sensors, and a pressure altimeter achieve the best combination of measurement qualities.
  • Dual on-board processors run a sophisticated Adaptive Kalman Filter (AKF) for excellent static and dynamic inclination estimates and inertial measurements.
Datasheet Manual

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 AHRS 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
