MicroIMU

Near-Tactical-Grade Miniature

Inertial Measurement Unit

The µIMU is a near tactical grade ultra-Miniature MEMS-based Inertial Measurement Unit.

The unit is the ­ generation of advanced Inertial Measurement Unit which is in use more than a decade 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 utilizes most advanced available MEMS-based sensor and deploys multiple-redundancy technology approach which assure not only fail-safe performance but considerable improved performance, these make the µIMU extremely cost-effective and a serious candidate to replace many FOG solutions that were used previously among control and many other applications.

Each unit of The µIMU is factory calibrated for Bias, Cross-Axis, non-Linearity, Scale-Factor & g- sensitivity over full-Temp range.

The ultra-miniature size of the µIMU unit with 1″x1″ (25 x 25 mm) dimension along its performance & low-cost making it serious candidate for many dynamic & static solutions, from simple control tasks and up to digital dynamic gyro-compensated tilt measurement in dynamic environments, among many different arenas in both defense and commercial related usage.
