Abstract
Car navigation and positioning system is a variety of technology in the integration of electronic equipment, mainly used in real-time, high speed to provide navigation, geographic information, etc. so as to improve urban traffic conditions, contribute to driving safety and increase the rate of road traffic.
This research mainly from the following aspects，first，studied the present situation of the automobile navigation and positioning system technology at home and abroad. Secondly， from the navigation system composed of the working principle and core functions made a detailed investigation.Then，studies the navigation system currently used in the actual system design methods and design ideas.Finally，on the basis of previous work，and put forward based on the embedded system of navigation methods d
esign train of thought，and from the two aspects of hardware and software design were expounded， namely design a S3C2440A ARM chip as the core，based on Linux operating system software development environment of car navigation and positioning system.In order to achieve low cost， small volume and high reliability design purpose.
Key words: Global Position System，Advanced Risc Machines，Car navigation and positioning system，Embedded system
