FOG-based IMUs

At pre-production phase

A range of newly developed FOG-based inertial measurement units (IMUs) feature miniature and lightweight design coupled with extremely low power consumption. They combine our smallest fiber optic gyroscopes and MEMS / pendulum accelerometers mounted on a solid frame. They also include a fully-integrated ADC board with RS422.

The U183(M) IMU comprises three VG1703-like FOGs and three MEMS accelerometers. It offers low noise performance in an ultra-compact cylindrical unit which is available in aluminium or μ-metal housing. 

The U121D IMU comprises three VG221-like FOGs and three MEMS accelerometers. It is a miniature 160-gram unit consuming groundbreaking 1.5 Watts of power. An analog output version is available on demand. The U123D model features cylinder-shaped design (∅40 x 100) and μ-metal housing.

The U173D IMU comprises three VG1703-like FOGs and three pendulum accelerometers. It delivers excellent ARW  in a 250-gram unit with 3 Watt powering. 


The U183(M), U121D and U123D are non-ITAR items
