The MicroStrain 3DM-CX5 family of high-performance, industrial-grade, board-level inertial sensors
provides a wide range of triaxial inertial measurements, computed attitude, and navigation solutions.
The 3DM-CX5-GNSS/INS all-in-one navigation solution features a high-performance, integrated multi-constellation
GNSS receiver utilizing the GPS, GLONASS, BeiDou, and Galileo satellite constellations.
Sensor measurements are fully calibrated, temperature-compensated, and mathematically aligned to an orthogonal
coordinate system for highly accurate outputs.
The auto-adaptive estimation filter algorithm produces highly accurate computed outputs under dynamic conditions.
Compensation options include automatic compensation for magnetic anomalies, gyro and accelerometer noise, and noise effects.
The computed outputs include pitch, roll, yaw, heading, position, velocity, and GNSS outputs — making it a complete
GNSS/INS (GNSS-Aided Inertial Navigation System) solution. Micro-Electro-Mechanical Systems (MEMS) technology
provides a highly accurate, small, lightweight device.
The CX product line includes all the same features as the GX series in a cost-effective, system-integrator-friendly package
designed for volume production.
