Based on multi-position rotation of the rotary laser gyro SINS, this method uses an anti-jamming coarse alignment method for coarse alignment, pensates the dimension effect errors caused by the rotation process, and finally conducts the fine alignment with taking the velocity as measurement information. The test results show that the horizontal alignment accuracy is superior to ′(RMS)and the azimuth alignment accuracy is superior to ′(RMS) when the alignment time is 300 s. This method is of putational amount, sim
