Liocrebif LKF-MSU105 is a miniature, cost-effective MEMS integrated inertial navigation system designed for SATCOM-on-the-move, UAVs, and similar navigation, control, and measurement applications. It tightly integrates MEMS sensors and a full-band GNSS receiver chip within a compact form factor, delivering precise positioning and attitude measurement in a small package.
