Discover the innovative design of a miniaturized Fiber Optic Gyroscope (FOG) IMU, offering high precision, low power consumption, and redundancy for aerospace, navigation, and industrial applications. Learn about its technical advantages and performance 1. While all our fibre-optic gyroscope INS offer highly accurate position and navigation data, our patent pending DFOG INS goes even further. iNAT-FSLG-01 is a light weight accurate fiber optic gyro (FOG) based INS of class 0. 01 deg/hr (AllanVariance bias stability) and 0. 1 deg/hr bias performace over full temperture range, consisting of 3 robust fiber optical gyros and 3 MEMS servo accelerometer axes, integrated GNSS Receiver (GPS. ANELLO Photonics builds next-generation inertial sensors you can trust. Our systems combine silicon photonics with advanced sensor fusion to deliver fiber-optic–class precision in a smaller, lighter, and more cost-efficient form factor - powering autonomy across land, air and sea. Designed for. bs using Tactical-grade Fiber Optic Gyroscope technology. The CIRUS and CIRUS-EX rate sensors deliver two different strategic grades of performance com ined with the benefits of a compact, low-cost system in an integral chassis.
