The System of GPS Navigation Based on ARM Processor

Using the ARM processor and the embedded operating system uC/OS-II as a development platform for designing navigation systems. The system uses GPS systems to obtain the latitude and longitude of the vehicles, by conversion and map-matching to get the actual location on the map, and then the user enter the destination, calculated the shortest path by A* shortest path algorithm and showed on the vector map. At the same time, it was extracted providing the speed, time and so on of GPS and displayed on the screen. The experiment shows that the system has steady performance, the high efficiency of communication, low power dissipation and suitable for the monitoring area of vehicle positioning.
