- As GNSS(Global Navigation Satellite System) is used in various filed, many countriesestablish GNSS system independently. But GNSS system has the limitation of accuracy andstability in stand-alone mode, because this system has error elements which are ionosphericdelay, tropospheric delay, orbit ephemeris error, satellite clock error, and etc. For overcomeof accuracy limitation, the DGPS(Differential GPS) and RTK(Real-Time Kinematic) systemsare proposed. These systems perform relative positioning using the reference and userreceivers. ETRI(Electronics and Telecommunications Research Institute) is developingprecision navigation system in point of extension of GNSS usage. The precision navigationsystem is for providing the precision navigation solution to common users. If thistechnology is developed, GNSS system can be used in the fields which require precisionpositioning and control. In this paper, we introduce the precision navigation system andperform preliminary design and algorithm verification
