The µIMU is a near tactical grade ultra-Miniature MEMS-Based Inertial Measurement Unit.
The unit is the 3rd 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 others 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 it's 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 defence and commercial related usage.
