| Abstract: | At present,gravity matching is one of the best options in underwater inertial aided navigation.Gravity anomalies' matching is the most important navigation estimation method in it.Because of the correlation between the true position and the normal gravity,simplex matching of gravity anomaly can not be realized in practice.The gravity anomalies' matching model is designed with the condition of normal gravity.The results from comparing simulation tests show that modified matching model can improve the effect of gravity anomalies' matching in the area with flat anomalies change. |
| Keywords: | underwater navigation gravity matching normal gravity model improvement |
