| Abstract: |
| The basic principle of Global Positioning System(GPS) and the construction of GPS-OEM board are introduced. The data format and information construction of NMEA-0183 standard is analysed. The serial communication between MCS-51 and GPS-OEM board based on the hardware construction is studied, and then the software and hardware configurations are discussed. Finally the communication program for reading the navigation message is provided. |
