VxWorks嵌入式环境下的GPS数据采集与处理

Embedded systems are developing rapidly in consumer electronics, Internet and other fields in recent years, they are increasingly deeper involvement and influence in our lives, work even entertainment. So it’s necessary to carry out research. This paper proposed a complete solution for GPS data collection and the processing system which hardware platform based on the ARM9 processor and software platform based on the VxWorks embedded operating system. Has studied under the VxWorks environment serial device driver, modified and built VxWorks board support package, introduced and parsed the NEMA-0183 communication protocol. Use client software to process the original GPS data frame, extract real-time longitude and latitude, time, date and other usefull information. Lay the foundation for the expansion application later on.
