The 3DM-GQ4-45 is a compact, tactical-grade all-in-one navigation solution with integrated GNSS and magnetometers, high noise immunity, and exceptional performance.


  • 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
  • Improved position outputs with concurrent tracking of up to two GNSS constellations (GPS/QZSS, GLONASS, BeiDou)
  • Smaller and lighter than most tactical grade GNSS/INS units
  • Bias tracking, error estimation, threshold flags, and adaptive noise, magnetic, and gravitational field modeling allow for fine tuning to conditions in each application
  • Fully calibrated, temperature-compensated, and mathematically aligned to an orthogonal coordinate system for highly accurate outputs


  • Easy integration via comprehensive SDK
  • Common protocol between 3DM-GX3, GX4, RQ1, GQ4, GX5, and CV5
  • Triaxial accelerometer
  • triaxial gyroscope
  • triaxial magnetometer
  • temperature sensors
  • pressure altimeter
  • GPS receiver
