- Abstract:
-
To ensure the position accuracy of the integrated navigation system consist of strapdown inertial navigation system(SINS) and Doppler velocity log in an autonomous underwater vehicle (AUV), it is necessary to accurately calibrate the misalignment angle between SINS and DVL and the scale coefficient of DVL. This calibration method only needs an AUV to expose above water surface for 2~3 times after having dived for about an hour. With the received GPS position as a reference information, the scale coefficient of DVL and the misalignment angle between SINS and DVL can be calibrated through iterative calculations. The experimental verification showed that all error parameters of the integrated navigation system can be calibrated easily and quickly by this method. It was concluded that after repeated calibration and error compensation, the position accuracy was better than 7m.
