I-FOG-25 Series Military Gyroscope

The I-FOG-25 series which are typical medium-precision all-digital closed-loop fiber optic gyroscopes, have the characteristics of low power consumption and high measurement accuracy. The product has excellent anti-shock, anti-magnetic field performance and great resistance to temperature, and can adapt to various of environment.

The I-FOG-25 series fiber optic gyroscopes contain: I-FOG-25-A, I-FOG-25-B, and I-FOG-25-C, which cover full medium-precision measurement, and are small-volume medium-high-precision motion sensors which provide solutions for the fields of attitude control, navigation and alignment, etc.
