1 Thumb-sized Fiber Optic Gyro VG191A & VG091-4LN

Measuring just 24mm in diameter and 40mm in length, the VG191A gyro offers low noise performance with 0.015 °/√h ARW and 2 °/h bias stability. The slightly longer (52mm) VG091A-4LN features exceptional performance of 0.01 °/√h ARW and 1 °/h bias stability.

Housed in μ-metal for enhanced magnetic immunity, the VG191A and the VG091A-4LN integrate both optics and electronics and require only 0.5W for operation. Their cylindrical design makes the FOGs ideal for such applications as pipeline inspection, underground utility mapping, borehole surveying, and more.

The VG191A and VG091A-4LN belong to the VG091 Series, featuringITAR-free FOGs with both analog and digital outputs and enhanced magnetic immunity.
