Product Description

The MicroStrain 3DM-CX7 is a high-performance, tactical-grade inertial sensor that combines MEMS inertial sensors with a magnetometer (AHRS only) and pressure sensor (AHRS only) for use in a wide range of applications. Common use cases include unmanned vehicle navigation, robotic control, platform stabilization, motion tracking and analysis, vehicle health monitoring, and device aiming.

The MicroStrain 3DM-CX7-INS is a tactical-grade Inertial Navigation System (INS) in a miniature package. The flexible EKF can accept external aiding measurements to maintain a robust navigation solution during GNSS outages and touts a feature set designed specifically for the timing requirements of the robotics and autonomous vehicle industries.

 

Key features
