Abstract :
The development of embedded intelligent device facilitates the application of the GPS system. In order to avoid performing conversion between different coordinate systems, a kind of GPS system is proposed based on free software by directly using WGS84 coordinate system and Mecator projection. In the GPS system, ARM-Linux operating system is configured on S3C2410 embedded development board, the electronic map of Zhengzhou city in TAB format is parsed using Mitab software package. Furthermore, through MiniGUI graphical user interface, various functions such as map viewing, map zooming and roaming can be realized. Through positioning tests, it is showed that the GPS system has reduced the positioning error, and is thus applicable to many platforms including various palmtop devices, smart phones and so on.
