| Abstract: | Satellite navigation systems are in widespread use in a large number of applications today, and a general trend is the demand for higher accuracy in real-time applications.So far, the advanced satellite navigation systems such as the American GPS and Russian GLONASS systems can provide highly accurate positioning and time-stamping services for the army.As the satellite navigation market grows, Europe is planning to launch its own Galileo satellite navigation system.In this paper, the existing GPS and GLONASS systems are described and compared, and the Galileo system proposal is also briefly introduced. |
