Abstract
In order to reduce the demand of precise turntable in the calibration of error parameters in strapdown inertial nav-igation system, a systematic calibration method based on velocity error was proposed. Based on the model of inertial sen-sors and error equation of SINS, the velocity errors of inertial navigation system before and after rotation were used as ob-servational vectors. Then the rotation scheme was designed to calibrate the error parameters of inertial sensors. The simula-tion results showed that, compared with the traditional calibration method, systematic calibration method has lower de-mand of precise turntable which can be applied to the field calibration while maintaining the calibration accuracy.关键词
