Study On Marine Integrated Navigation System

Integrated navigation is the trend of the navigation and positioning development Integrated navigation systems have become an important accessorial equipment in modern vessel's navigation system. Many powerful countries compete to research it as a way of navigation. In this paper, SINS is regard as a reference system, and a SINS/GPS/Loran-C/WYBD integrated navigation system is designed.The history of integrated system and its recent marine application are introduced. By analyzing factors of the Loran-C and Bei-Dou Double Star System, the model of the Loran-C, RDSS and WYBD is established severally. The optimal prediction model of SINS/RDSS is established in the case of position compensation, the result of theoretical simulation experiment is researched.According to the introduction of the theory about federated filter and the features of marine navigation, SINS/GPS/Loran-C/WYBD integrated navigation system is designed. The result of theoretical simulation experiment is researched.At last, the static and dynamical datas of ship on the sea are get by the data collection system designed. The result of the semi-physical simulation concludes that the Federal Filter designed in this paper is feasible.
