摘要
卫星导航系统现已渐渐成为人们日常生活的一部分。介绍基于ARM920T内核的微处理器S3C2440A和WinCE 5.0操作系统实现嵌入式导航系统设计。重点讲述UART接口的iTra300芯片在系统中实现GPS定位和导航的方法,最终设计结果已满足日常需要。这里将UART接口芯片用于GPS接收,大大降低了系统设计难度,提高了定位精度。
Nowadays, navigation system has became one part of our daily life. The thesis introduces the design of embedded navigation system based on S3C2440A with the kernel of ARM920T and the embedded operating system of Win CE 5.0. The Method of orientation and navigation with the iTra300 of UART interface is introduced, the results meet the need of daily life. Application of the chip with UART interface lowers the difficulties of design and improves the precision of orientation.
