Fiber Optic Gyro G121

The G121 three-axis fiber optic gyroscope (FOG) features an ultra-low-SWaP design with low noise performance. The units contain three single-axis FOG sensors mounted on a solid frame, as well as a fully integrated ADC board. Other key features include almost instant initialization and low power consumption of just 2 Watts.

The three-axis gyro is available in an aluminium alloy or μ-metal case.
