| Abstract: | A Global Positioning System(GPS) compass data acquisition and processing system based on multi-thread technology is designed. This paper describes the principle of GPS attitude determination and related communication protocol. With the example of the SDI-COMPASS, a solution based on the API communication function of Win32 is realized, which achieves the multi-thread and overlapped I/O communication between GPS compass and PC via serial port. The static and dynamic experiments show that the system is capable of gathering and processing GPS compass data quickly and correctly, and performs with high stability and flexibility. |
