Qun Zong

Abstract

Vehicle GPS navigation system developed on the basis of GPS has positioning,speed measuring,navigating and voice prompting functions.The structure of vehicle GPS navigation system and target platform of the system are introduced.The hardware of the system based on S3C2440A and SDT11 GPS module is designed.Under Windows CE embedded OS write serial communication software to complete GPS information receiving.Then introduce the protocol of GPS data output.According to this protocol make use of EVC programming to finish GPS information processing,realize the function of positioning.Based on the above,embed electronic map to realize the function of navigating,then complete the vehicle GPS navigation system.
