    Factory calibration of Inertial Navigation Systems (INS) involves using high-precision multi-axis turntables and environmental chambers to determine sensor errors—bias, scale factor, and misalignment
    . Key techniques include multi-position static testing , rate table rotation , and thermal cycling (

    − 4 0 ∘ C
    to
    85 ∘ C 85 raised to the composed with power C
    8 5 ∘ C
    ), aimed at identifying over 21 error parameters for high-performance units.
    Key Factory Calibration Techniques
    • Multi-Position Calibration : The Inertial Measurement Unit (IMU) is placed in specific orientations (e.g., 12 or 30 positions) on a rate table to measure accelerometer bias, scale factor, and gyroscope drifts.
    • Rate Table Testing : The IMU is rotated at precise rates to calibrate gyro scale factors and misalignment.
    • Thermal Calibration : The IMU undergoes temperature cycling to model and compensate for bias and scale factor changes, crucial for high-performance sensors.
    • System-Level Calibration : Determines the transformation matrix between the IMU, inner gimbal, and outer gimbal coordinates for gimbaled systems.
    • Automatic/Fast Calibration : Utilizes algorithms like Kalman filtering or least squares on, for instance, a two-axis turntable to speed up the calibration process.
    • Component-Level Testing (Burn-in) : Electronic boards undergo burn-in to ensure reliability before assembly.
    Commonly Calibrated Parameters
    1. Bias (Zero-bias): The output when no input is present.
    2. Scale Factor: The ratio of the output signal to the input physical quantity.
    3. Misalignment/Orthogonality: The deviation of the sensor axis from the ideal orthogonal coordinate system.
    These methods ensure that raw data is corrected for repeatable errors, significantly improving the accuracy of the INS before deployment.
