UF100A fiber optic inertial group is a middle precision and small size IMU as Figure 1 shown. It is used to detect the angular velocity and linear acceleration of the carrier's motion, providing information for the carrier's attitude and navigation control. It has the advantages of small size, light weight, no moving parts, high reliability, and long service life. It can be widely used in aviation, aerospace, ships, weapons, coal mine measurement, automotive electronics and other fields.
