The authors proposed a new central navigation system based on switching between COMPASS and global positioning system (GPS).After analyzing the signal carrier to noise ratio of the two positioning modes,the system achieved dual mode switch and solved signal incontinuous problem in the general dual-mode positioning system.Also the dynamic traffic information has been introduced into the process of routing planning,which helps to solve the problem that traditional vehicle navigation system can not provide flexible routing planning based on real-time traffic condition.This paper formulates simple data transfer protocol between vehicle and server,which simplifies the general protocol between them. Experimental results show that this system can maintain a higher quality of satellite data and has achieved the goal of the dynamic navigation based on traffic situation.
