3DM-GQ4-45™ GNSS-Aided Inertial Navigation System

Description

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.

High performance integrated multi-constellation GNSS 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
Improved position outputs with concurrent tracking of up to two GNSS constellations (GPS/QZSS, GLONASS, BeiDou)

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 0.002°/sec/√Hz and VRE of 0.001°/s/g2RMS
Smaller and lighter than most tactical grade GNSS/INS units

Ease of Use

User-defined sensor-to-vehicle frame transformation
Easy integration via comprehensive SDK
Common protocol with the 3DM-GX3® , 3DM-GX4® and 3DM-RQ1™ sensor families for easy migration

Cost Effective

Out-of-the box solution reduces development time
High performance tactical grade outputs at an industrial grade price
