摘要：

设计一种基于北斗和全球定位系统（global positioning system, GPS）双切换的中心导航系统. 该系统对两种定位模式信号载噪比进行分析, 灵活切换定位系统, 解决了普通双模定位系统中信号有效性不连续的问题；并将动态路况信息引入路径规划过程, 解决了传统车载导航无法根据实时交通状况进行灵活规划的问题；制定了车台与中心服务器间简易数据传输协议, 简化了传统车服通信协议. 实验结果表明, 该切换系统可使卫星数据保持更高的质量并实现了根据交通状况的动态导航.

Abstract:

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.
