The VG191A is an ultra-miniature single-axis fiber optic gyroscope that provides high-performance angular rate measurement in an extremely compact and lightweight package. Measuring just 24 mm in diameter, the cylindrical FOG sensor features instant startup, low power draw and a 15-year lifetime.

The IP67-rated sensor provides an analogue output, and is available with either robust aluminium alloy or magnetically-shielded μ-metal housing options. It is ideal for small and space-constrained marine vessels and submersibles.
