Description

The MicroStrain 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 extremely accurate outputs. The highly linear sensor performance and auto-adaptive estimation filter algorithm produces very accurate computed outputs under real-world dynamic conditions.

The CX product line has all the same features of the GX series in a cost-effective system-integrator friendly package designed for volume production.

 

Use Cases
