Introduction

High-performance Dynamic FOG North Seeker

Introduction
ER-FNS-01D high performance dynamic fiber optic gyroscope north seeker uses closed-loop fiber optic gyroscope as its core component. It is mainly composed of inertial measurement unit (IMU), digital signal processing unit and the mechanism of various mechanical components. It can accurately provide true north azimuth for the carrier under vibration environment and provide accurate attitude tracking function.

Feature
Internal shock absorber, can adapt to large impact and vibration;
30s fast alignment, azimuth accuracy 1°; 90s accurate alignment, azimuth accuracy 0.5°;
Dynamic north finding, accurate north finding and attitude following in the case of vibration;
Not affected by magnetic field;
5 ~ 55°C full temperature compensation, adapt to extreme environment.

Application
Mining
Pointing, steering and guiding in advanced mining/drilling equipment
Petroleum exploration
North seeking in logging tools/gyro tools
Initial alignment/UAV launch systems
North finding in land surveying/land mobile mapping system
