Research Of Marine Beidou/GPS Combined Navigation Terminal

Compass navigation system as our implemting self-development and independent operation of the global satellite navigation system, It promotes the development of our satellite navigation cause, reflects the comprehensive power of our country, makes us getting rid of our dependence on foreign satellite navigation system, and also breaks the American monopoly of GPS, led a group of China's high-tech industries, format a new source of technology growth. china's navigation system as a new product of the time, in order to develop and grow, the first step must be compatibled with other navigation systems under the framework of global. This thesis aimed to research marine beidou and GPS combined navigation terminal, at the development of China navigation industry, combined with the demand of our marine navigation.Firstly, This thesis elaborated the development of the navigation, the selection of the background and significance. And explained the development, composition, theory of beidou and GPS navigation system.Thereafter analysis the function of more than a dozen of marine navigation terminal in thesis, combining our situation and giving the function of this combined navigation terminal;then general designed the function of combined navigation terminal; Combining with the actual situation of our navigation system's development,the suggestion data transport protocol standards of beidou navigation receiving machine is given out.Then Achieved two main function modules of the joint terminal:Positioning and navigation function module. And the simulation test was achieved running on VC++ platform of PC. Finally, This article was conducted a preliminary explore to the Compass and GPS combination which based on the information fusion technology.
