FOG IMU U183(M)
The U183 is a FOG-based inertial measurement unit (IMU) with an ultra-compact cylindrical form factor. Featuring three FOGs and three MEMS accelerometers, it delivers low noise performance and includes a fully-integrated ADC board with RS422 serial communications. The unit is available in either aluminium or μ-metal housing.
The miniature non-ITAR IMU is ideal for a range of unmanned systems applications, including inertial navigation for UAVs, USVs and UUVs, and drone flight control.
