Introduction

ER-FNS-01 High Performance Dynamic FOG North Seeker (0.02°-0.5°)

Introduction
The ER-FNS-01 high-performance dynamic fiber optic gyro north finder uses a closed-loop fiber optic gyro as its core component. It is mainly composed of an inertial measurement unit (IMU), a digital signal processing unit, and the mechanisms of various mechanical components. It can accurately provide the true north azimuth for the carrier in a vibrating environment and provide accurate attitude tracking functions.

Feature
1. With internal shock absorbers, it can adapt to large shocks and vibrations;
2. Quick alignment in 30 seconds, precise alignment in 90 seconds;
3. Dynamic north search, which can accurately search for north and follow the attitude in the presence of vibration;
4. Not affected by magnetic fields;
5. Full temperature compensation of 5 ~ 55°C, adapting to extreme environments.

Application
Mining
Advanced mining/drilling equipment pointing, steering and guidance
Oil exploration
Initial alignment/UAV launch systems
