| Abstract: | This paper describes a new method of improving GPS precision.By making use of it,the modelling and one step estimating can be made accurately.Based on the modelling,the GPS positioning precision can be improved by 3 to 5 times with Kalman filtering.The method is very useful for the optimum control of vessel navigation and the users who cannot use the differential GPS. |
