    Wholesale calibration of Inertial Navigation Systems (INS) involves using high-precision multi-axis turntables to estimate deterministic errors—specifically bias, scale factor, and non-orthogonality (misalignment)—for accelerometers and gyroscopes
    . Common methods include multi-position static tests, automated rotation modulation for self-compensation, and Kalman filtering to refine parameters .
    Key Calibration Techniques & Procedures
    • Multi-Position Turn-Table Calibration : The INS is placed on a precision rate table and moved to specific, known orientations (e.g., 6, 9, or 12 positions) to isolate the effects of gravity on accelerometers and Earth’s rotation on gyroscopes.
    • Rotation Modulation : Used in Strapdown INS (SINS) to continuously modulate sensor errors, allowing for real-time or near-real-time self-compensation of bias drift and non-orthogonalities.
    • Weighted Least Squares (WLS) & Kalman Filtering : These algorithms process the data collected from the turntable to estimate the error parameters, minimizing the difference between expected and measured values.
    • Rate and Acceleration Tests : Beyond static positions, constant rate, and sine-sweep tests are used to determine sensor bandwidth, linearity, and scale factor errors.
    • Self-Calibration and In-Field Alignment : Techniques that do not require external, high-precision references, instead using the system’s own motion (e.g., in-motion alignment) or Schuler loops to calibrate in the field.
    Commonly Calibrated Parameters
    • Bias: The non-zero output of a sensor when the input is zero.
    • Scale Factor: The ratio of change in output to the change in input, determining measurement linearity.
    • Misalignment (Non-orthogonality): The deviation from a perfect
      90 ∘ 90 raised to the composed with power
      9 0 ∘
      orthogonal frame between the sensor axes.
    • Lever Arm Effects : Compensation for the physical distance between the INS center and the vehicle's navigation reference point.
