Research on Large Voyage AVU SINS/DVL Combined Navigation Orientation Precision
2010
In order to improve the precision of AUV navigation orientation and research the application of SINS/DVL combined navigation system in the large voyage AUV. Firstly,the model of analyzing error will be established. Secondly,calculate the error by the normal kalman filter equation; lastly,use simulation to analyze the error by the normal kalman filter arithmetic with known system yawp and observation yawp. The result indicates that error array will be not non-negative definite any more because the filter is divergent obviously,it will make influence the filter increment.
