As Global Positioning System(GPS) could provide some navigation information for users such as time, latitude, longitude, and altitude, etc, it has been widely used in various fields like military, communication, measurement and so on. Therefore, it is of great application importance to study the processing method and display way of GPS navigation information. In this paper, on the basis of the positioning principle of GPS, the GPS navigation information processing method is proposed which has combined the PC and the receiver serial communication. The focus of this program is to study the software to process and display the GPS navigation information using the visual programming of VC++. The GPS receiver serial port is used to send real-time navigation information to the PC in this program, and then the time, latitude, longitude, altitude and satellite status and some other information can be displayed in the window frame created by MFC after the extraction of MsComm controls serial port programming. Meanwhile, the received time information can be used to make the simple calendar; the electronic map is loaded with the electronic map control MapX, and then electronic map location function can be achieved using the location information. This design can process and display various GPS navigation information conveniently after the actual test, which can be used in a variety of occasions.
