U121D

The U121D is a FOG-based inertial measurement unit (IMU) combining three axes of Fizoptika's smallest fiber optic gyroscopes with three axes of MEMS accelerometers. Weighing just 145g with a power consumption of only 1.5W, the IMU incorporates a fully-integrated three-channel ADC board with serial RS422 output, and an analogue version is available upon request.

The non-ITAR IMU is enclosed in a robust aluminium housing, and is ideal for marine vessels, USVs and ROVs, as well as for integration into higher order systems such as inertial navigation systems (INS).
