Introduction

ER-FNS-02 High Precision FOG North Seeker (0.02°-0.1°)

Introduction
ER-FNS-02 High Precision FOG North Seeker (0.02°-0.1°) is mainly composed of closed-loop FOG, inertial measurement unit, digital signal processing unit and the mechanical part. It provides high precision true north azimuth information to carriers.
The products are mainly used in static initial alignment of missile launch, weapon targeting and direction control of radar, antenna and armored vehicle, also can be used for coal mining, oil drilling, tunnel construction and geodesy.

Applications
North seeking
Navigation and control
Attitude reference system
Guidance
Vehicle and ship attitude measurement
Integrated inertial/satellite navigation system
Drilling and production system
Mobile mapping system
