Abstract
This paper discusses a kind of design method that combines S3C2440 and GPS module to realize the GPS navigation terminating machine,which needs to establish environment of embedded development ARM9 and install Linux operating system.The key technologies include: extraction of RMC statements,collection of GPS data,Qt programming and matching algorithm of electronic maps and GPS data,in order to display and move the GPS navigation maps for achieving the purpose of real-time location.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
