Introduction

ER-FNS-03 Low Cost 3 Axis FOG North Seeker

Introduction
ER-FNS-03 Low Cost 3 Axis FOG gyro North Seeker adopts closed-loop fiber optic gyroscope as the core component. It is mainly composed of inertial measurement unit (IMU), digital signal processing unit and the organizations of the mechanical parts. It can provide the carrier with true north azimuth angle.

Applications
