AI Overview
Factory IMU calibration ensures accuracy by compensating for bias, scale factor, and misalignment errors using specialized, high-precision equipment. Key methods include
multi-position static testing (6 or 12-position tumble tests) for accelerometer/gyro bias, thermal chamber calibration to map temperature drift, and rate table testing for rotational accuracy
. These techniques generate correction matrices applied during production.
