    Factory-level accuracy for Fiber Optic Gyro (FOG) Inertial Measurement Units (IMUs) is primarily influenced by temperature-induced drift, mechanical stress, calibration quality, and sensor mounting precision
    . Key factors include:
    • Temperature Variations: The most significant factor; fluctuations cause bias instability, requiring rigorous thermal compensation during factory calibration.
    • Calibration Range and Density: The number of temperature points and the dynamic range (angular velocity/acceleration) covered during calibration determine the final accuracy.
    • Mechanical Stress & Vibration: Environmental factors, such as vibration, can cause output inaccuracies.
    • Time Asynchronous Data: Inaccurate timing between sensors during high-dynamic calibration can degrade performance.
    • Internal Component Quality: The quality of the fiber optic coils and optical components.
    Key Factors Influencing FOG IMU Accuracy
    • Thermal Sensitivity : FOGs are highly sensitive to temperature changes, leading to physical expansion/contraction of components, creating bias and scale factor errors.
    • Calibration Rigor : The calibration process determines the sensor's accuracy, specifically addressing sensor bias, scale factor stability, cross-axis sensitivity, and misalignment.
    • Dynamic Environment : The ability of the FOG to handle high-dynamic situations, like rapid turns or heavy vibrations, is critical, particularly in aerospace applications.
    • Sensor Aging : Long-term drift or changes in components can affect performance over time, which need to be accounted for in production.
    • Internal Components : The quality of the fiber optic coil, light source, and electronics defines the base accuracy.
    Factory Calibration Process
    • Error Modeling : Factory calibration involves creating precise models to correct deterministic errors.
    • Temperature Testing : The IMU is tested across a wide temperature range to calibrate against thermal drift.
    • Dynamic Testing : The unit is placed on precision rate tables to calibrate scale factor and bias in dynamic conditions.
