FOG IMU U123D
The U123D is a FOG-based inertial measurement unit (IMU) with a lightweight ultra-compact design and robust aluminium housing. Featuring three FOGs and three MEMS accelerometers, it consumes just 1.5 Watt of power and includes a fully-integrated ADC board with RS422 serial communications.
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.
