Fiber optic gyroscope (FOG) calibration involves
temperature compensation
,
bias stability adjustment
, and
scale factor calibration
using a high-precision multi-axis turntable to ensure accurate navigation and stabilization. Key methods include
rotational testing on a rate table to determine bias, scale factor, and nonlinearity, followed by digital compensation algorithms
.
Key Calibration Techniques & Methods
- Rate Table Calibration: The FOG is mounted on a single-axis or multi-axis turntable, which rotates at known speeds to compare output signals against reference values to determine , bias, and scale factor.
