摘要

全球定位系统(GPS)广泛应用于系统定位或导航通信,码分多址(CDMA)应用于个人通信和数据传输等领域。本文简要介绍了CDMA短消息数据的数据格式和GPS数据流的数据格式,并在此基础上对基于嵌入式Linux操作系统的GPS和CDMA应用系统在位置导航、远程控制、数据传输和个人通信等方面进行了研究。最后给出了硬件设计方案和应用程序流程。所有的应用程序都是在嵌入式Qt平台和嵌入式Linux下设计的。

Navigation and Positioning System Based on GPS & CDMA
Global Positioning System (GPS) is widely used in system positioning or navigation communication, and code division multiple access (CDMA) is applied in personal communication and data transmission etc. In this paper, the data format of short message data in CDMA and the data format about GPS data stream are introduced in brief, and then a GPS and CDMA application system based on embedded Linux operating system is researched in position navigation, remote control, data transmission and personal communication. Finally the hardware design scheme and the application program flow scheme are given. All application programs are designed under embedded Qt platform and embedded Linux.
