The applications of global positioning system(GPS)are more and more widely used in people’s life. With a high precision, long standby time, global coverage, convenience, flexibility and high quality but low price, the GPS plays an essential role to people around the world. At present, GPS positioning and navigation technologies are not only used in geodesy, vehicle location and other professional fields, but also in the individual applications. According to the individual applications, the portable GPS track logger scheme has been designed and developed, basing on the STR711FR2 micro control unit(MCU)of STMicroelectronics and the GPS receiving module of MStar. The paper emphasizes on the parts of software which is based onμC/OS-II embedded operation system. The subject designs a software system that can meet the requirement on portable GPS track logger and realize four founctions which include communication function, connecting function, storage function and human-computer interaction function.
