Abstract:
    A distributed navigation system implementation method, its features are: the implementation of navigation functions is distributed in the two parts, the information service center and terminals, the information service center implementing GIS path analysis and path planning function, and storage, processing, analysis and display of the vector electronic map all completed in the information service center, the terminals only for simple navigation information analysis and calculation. It not only ensures that the hardware requirements of the system to the terminals is very low, greatly reducing the cost of navigation products, but only that the information center servers need only maintain a GIS system and vector electric map data, upgrading system and updating data very easily.
