| Abstract: | In the article, two key issues of on online-calibration of LSINS based on two-axis indexing were discussed: (1) an online-calibration model for the laser gyro strap-down inertial navigation system was deduced, the condition under which the proposed model was discussed; (2)the principles of the calibration experiment design were proposed. This method is simple, time-saving and high-precision. |
