The satellite radio navigation is a youthful engineering application science, the concept of which is still being developed and evolved. The basic principle of satellite navigation is that the navigation satellite operating on the designated orbit transmits radio navigation signals continuously under the control of the satellite clock, and the user receiver receives navigation signals from at least four satellites. Besides the basic methods of determining user's position listed, there are still a lot of combined methods that adopt the additional measuring devices provided by the user, except for the satellite navigation system. Specific form of navigation function depends on many factors: form of navigation parameter, kinetic characteristics of the satellite and user, selected coordinates, and others. The user who requires extremely high accuracy can adopt carrier phase difference technology. The positioning and velocity measurement performance is continuous and suitable for dynamic performance of the user in motion.
