嵌入式GPS数据采集与分析系统设计

摘要

介绍了一种基于嵌入式Linux系统和ARM9处理器的手持式GPS数据采集、处理、显示接收机的设计过程.采用ARM-Linux和ARM9处理器的系统作为开发平台,控制OEM板接收导航信息,并给出了GPS数据采集系统详细的软件设计方案,给出了提取GPS特征数据的算法.这些对研究嵌入式系统应用、GPS定位及其在组合导航中的应用以及对OEM板的二次开发等都具有实用价值.%This paper introduced the design process of the GPS data receiving, collecting, processing, and display software of the GPS receiver based on Linux and ARM 9 processor.The paper used ARM-Linux and ARM9 processor as the device development platform to control the OEM board received navigation data.The detailed software design of the GPS data collecting system and the GPS feature data algorithm were presented, which are of practical value for the embedded system application, GPS positioning as well as its application on the integrated navigation, and the secondary development of the OEM board.
