Inertial measurement unit ER-FIMU-40

ER-FIMU-40 High Accuracy FOG IMU
Introduction
ER-FIMU-40 FOG inertial measurement unit is specially developed for tactical system applications. The product consists of all solid-state three-axis fiber optic gyroscope, three-axis quartz flexible accelerometer, body structure, data interface board and other components.




Features
 It does not rely on external signals such as GPS/BDS and base stations. It can work independently in underground, underwater and GPS-denied environments, providing continuous angular velocity and linear velocity data.




No wearing parts, long service life and high reliability




Fast dynamic response, suitable for complex motion scenarios




Wide temperature range operation: -50 to 80. Suitable for extreme temperature and humidity scenarios such as polar regions, upper air, and deserts, without performance degradation




Small in size, light in weight, and easy to integrate




Applications
Communication satellite antenna pointing




Underwater robots (ROV/AUV), underwater cleaning equipment




The primary/backup inertial navigation systems for helicopters (rescue, mapping, transportation types), suitable for low-altitude flights and mountain rescue scenarios




Coal seam mining, underground mining equipment for non-ferrous metal mines




Geographic information mapping, such as urban topographic mapping and farmland water conservancy mapping




Subway tunnel boring machine (TBM)




Medium and large-sized civilian unmanned aircraft
