Introduction
ER-FNS-01 High Performance Dynamic FOG North Seeker (0.02°-0.5°) consists of high precision, rugged solid FOG, quartz accelerometer, data acquisition and processing unit. It can provide the true north azimuth information of the carrier when the carrier is moving. At the same time, the information of motion attitude, velocity and position of the carrier can also be displayed. This dynamic north seeker is suitable for static and dynamic initial alignment of missile launch, weapon aiming, direction control of radar, antenna and mapping survey.
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
