Design of vehicle positioning system based on ARM

This paper discussed a kind of design of vehicle location system based on ARM. The architecture and working theory of this system is introduced in details, and introduces the vehicle location system which uses the ARM microprocessor LPC2129 as a control unit to combinative with GPS LR9548 and GSM TC35 modules. Explores location solution, map—matching and data compress that associated with the positioning, shows a program flowchart and predicts the trend of the vehicle location system in the future.
