Introduction

ER-FIMU-70 FOG IMU

Introduction:

ER-FIMU-70 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 accelerometers, body structure, data interface board and other components.

It can measure the triaxial acceleration and angular velocity of the object, and is generally used in the measurement link of the system to estimate the posture of the object. The accelerometer detects the independent three-axis acceleration signal of the object in the carrier coordinate system, the gyro detects the angular velocity signal of the carrier relative to the navigation coordinate system, and the attitude of the object can be calculated according to the measured angular velocity and acceleration of the object in three-dimensional space.

Applications

Inertial navigation of surface-to-air missiles

Air-to-air missiles and navigation missiles

Space stabilization systems, mapping systems, attitude reference systems, motion compensation systems, imaging stabilization systems, flight control systems

Air combat maneuvering instruments

Navigation test equipment
