Fiber Optic Gyroscopes
Zero moving parts. Sagnac-effect precision. Proven reliability.
Our fiber optic gyroscopes leverage the Sagnac effect for rotation sensing with zero moving parts. Available in single-axis, dual-axis, and tri-axis configurations with bias stability from 0.003°/h (strategic grade) to 2°/h (industrial grade). Ideal for INS, platform stabilization, north-finding, and precision pointing.
