dc.description.abstractThe Precise Point Positioning technique (PPP), which emerged as an alternative to the conventional relative positioning method, has been widely used in many applications in recent years. The PPP method is a special case of absolute positioning method, in this method the static and kinematic position can be determined with high accuracy by using single GNSS receiver. On the other hand, thanks to the real-time precise orbit and clock products made available by different establishments and organizations (International GNSS Service-IGS, Federal Agency for Cartography and Geodesy-BKG, European Space Agency-ESA, European Reference Frame-EUREF, German Research Centre for Geosciences-GFZ etc.), PPP method has started to be used in applications that require real-time position information. The high interest in this method, which is called real-time-PPP (RT-PPP), has accelerated the development of the method. Many software have been developed in this context. In this study, the positioning performance of RT-PPP method was investigated using BKG/BNC (BKG Ntrip Client), RTKLIB/RTKNAVI (Real Time Kinematic Library) and PPP-WIZARD (PPP With Integer and Zero-difference Ambiguity Resolution Demonstrator) software. For this purpose, real time coordinate values of ISTA IGS station, located in Istanbul, belongs to the observation period of about 25 hours were obtained in 1 second epoch interval. The obtained results were compared with the reference coordinates of the station, and examined in terms of accuracy and precision. According to the results, it has been observed that the convergence time sometimes exceeds 1 hour, and after this time, an accuracy of approximately +/- 10 cm in horizontal component and +/- 20 cm in vertical component could be obtained with BKG/BNC and RTKLIB/RTKNAVI. However the accuracy of the coordinates obtained using the PPP-WIZARD software is over +/- 30 cm due to the large number of disconnections and subsequent convergence.en_US
