摘要
文章分析了车载GPS导航系统的现状,并从差分GPS原理出发,分析和设计了适合嵌入式平台应用的差分算法,提出了一种能够在嵌入式平台上采用的定位算法,同时设计了基于PowerPC处理器的Total5200平台上的嵌入式Linux操作系统,并实现了嵌入式Linux到Total5200平台的移植。文章最后给出了在Total5200平台上的GPS位置差分算法的原型系统实现。
In the article,the actuality of the vehicle GPS navigation system is firstly analyzed,and then the author analyzes and designs the suitable DGPS arithmetic on embedded platforms from the DGPS theory.A kind of orientation arithmetic suitable for embedded platforms is then brought forward.At the same rime,the embedded Linux OS on Total5200 platform based on PowerPC processor is designed,and the embedded Linux porting on the platform is realized.At the end,a prototype system realization based on the position DGPS arithmetic on Total5200 platform is given.
