Ultra-Miniature Fiber Optic Gyro Developed for UAVs

Published: 14 May 2020 by

Fizoptika VG191A fiber optic gyroscopeFizoptika has launched the VG191A, the company’s smallest ever differential-output fiber optic gyroscope (FOG). It is the newest addition to the VG091 series of FOG sensors, which combine miniature analogue processing electronics with a sensing assembly fabricated from a single length of optical fiber by a fusion-tapering technique.

Enclosed in a rugged aluminium alloy package only 24mm in diameter, 40mm in length and weighing just 30 grams, the VG191A is ideal for the most SWaP (size, weight and power)-constrained UAVs (unmanned aerial vehicles), robotics and unmanned systems. The sensor features a 15-year lifetime and enhanced resistance to shock, vibration and temperature, making it suited to operation in highly demanding application environments.

The compact, lightweight sensor delivers excellent performance with 0.015 deg/√h ARW (angle random walk) and a bias stability of 1 degree/hour.
