AI Overview
Calibration techniques for Fiber Optic Gyroscope (FOG) Inertial Measurement Units (IMUs) are essential for correcting errors in scale factors, drifts, installation, and lever-arm parameters to enhance navigation accuracy. These techniques range from traditional multi-position, turntable-based methods to advanced hybrid and online calibration methods designed to handle high-dynamic environments and improve in-field performance.

What is the 4 to 1 calibration rule?
A 4:1 TUR is the point to which most high-quality calibration labs strive. It is the point at which the level of in-tolerance probability stays at 100% the longest, with the best economies of scale. The technology of the respective T&ME is approaching the intrinsic level of the specific discipline.

Five-Point Calibration Method
Test at 0%, 25%, 50%, 75%, and 100% of span in both directions (increasing then decreasing). This identifies span errors, zero errors, linearity problems, and hysteresis. Record applied input, measured output, and calculated error at each point.Dec 13, 2025
