U183

The U183D is a FOG-based inertial measurement unit (IMU) combining three axes of MostaTech's smallest fiber optic gyroscopes with three axes of MEMS accelerometers. With a compact cylindrical form factor of 46 x 111mm and a power consumption of only 2W, the IMU incorporates a fully-integrated three-channel ADC board with serial RS422 output.

The low-noise IMU is available with an aluminium or magnetically-shielded μ-metal 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).
