| Abstract: | A software GPS positioning receiver which can be easily integrated into embedded system was designed.The receiver has three work modes: autonomous,snapshot and assisted.According to the availability of GPS signals,the receiver changes work mode neatly,so as to offer steady position information with low power consumption and low CPU burden.Field tests were done,and the results indicated the good performance of the positioning receiver. |
