As GNSS(Global Navigation Satellite System) is becoming more common all over the world, the satellite navigation system is used in many fields such as positioning, navigation, timing, land survey, and so on. The satellite navigation covers all around world and can be used in everywhere if the satellite signal could be received. But the performance of positioning has the limitation due to the way of satellite navigation. The satellite navigation system has the error elements which are ionospheric delay, tropospheric delay, orbit ephemeris error, and other errors in calculation of positioning. These error elements degrade the positioning accuracy and the reliability of satellite navigation system. If these problems which make the usage of satellite navigation system be limited are resolved, the usage will be extended more than present. ETRI(Electronics and Telecommunications Research Institute) is developing precision navigation system for sub-centimeter positioning. This system is for providing precision navigation service and securing the application technology in satellite navigation system. This technology has important point in future navigation market and application. In this paper, we introduce the precision navigation system and design process. The navigation algorithm to be applied in the system is analyzed.
