| Abstract: | Three calibration methods for laser gyro strapdown IMUs were compared and researched. The calibration principles of various methods were analyzed in detail. Based on the standard deviation, the evaluation index of calibration methods was proposed. According to analysis of calibration experiment results of some laser gyro strapdown IMUs, the comparison results of three calibration methods on calibration time and calibration precision were obtained without north-seeking.
