The VG221LN is a member of Fizoptika Malta's most compact and lightweight series of FOG sensors, measuring just 33 mm in diameter and weighing only 15 grams. It features high-accuracy measurement capabilities and ultra-low noise performance of just 0.025°/√h.

Like all Fizoptika Malta gyroscopes, the miniature FOG unit contains fully integrated optics and electronics. With an extremely low SWaP (size, weight and power) footprint, it is ideal for a wide range of unmanned vehicle and robotics applications such as gimbal and platform stabilization.
