Abstract
GPS information collecting and processing is an important part of the navigation and positioning system. Through the establishment of cross-compiler environment, using the ARM processor S3C2440A and Linux operating systems as the hardware and software platform and the GS87 is used as GPS receiver module, the NMEA-0183 communications protocol and serial asynchronous communication between the ARM platform and GS87 module are analyzed. Through the serial port programming, GPS information collecting and processing system is realized. By querying the GPRMC statement and the corresponding conversion, the useful information is separated. The final practice has proved that the system data is of high precision, real-time property and good practical value.
