A single axis gyroscope, providing outstanding stability with low noise.

The unit has comparable bias characteristics to FOG (fibre-optic gyros) and DTG (dynamically-tuned gyros), and is available in five dynamic ranges. The new CRH03 offers uprated performance over the highly successful, previous generation CRH02 gyro due to improvements in both MEMS and electronics.
