VG 091B is the fiber optic gyroscope system (sensing optics and full processing electronics in one housing) having the lowest diameter along its sensitivity axis.
Just +5V and 0.02s for get full performance.
Lowest 0.5 W power
Widest 1kHz bandwidth
Same interface as VG 091A. Using both models gives opportunity to build 3-axis system with diameter 30mm
