µIMU-HG

near-Tactical-Grade Miniature Inertial Measurement Unit

arazim is expanding the µIMU family to include new member with hi-g measurement capability.

now, compromising of 3-axis Gyro, 3-axis accelerometer to deliver optimal performance where size, cost & performance (SWaP-C) are of prime concern.

The µIMU-HG utilizes most advanced available MEMS-based sensor and deploys multiple-redundancy

technology approach which assure not only fail-safe performance but considerable improved performance
