Abstract(in English)	Precise Point Positioning (PPP) is an independent precise positioning scheme using GPS precise orbit/clock ephemerides and carrier-phase observables without reference stations. This paper introduces the PPP measurement model and the estimation strategy. After that, we report evaluation results of PPP accuracy using GPS precise analysis software GPS Tools (GT), that we are currently developing. At first, IGS reference frame stations' positions were determined using GT PPP and compared with the coordinates according to International Terrestrial Reference Frame (ITRF). There was apparent 1.5-2cm range vertical error in PPP results. With this error correction, PPP is able to archive the accuracy of 3mm horizontally and 8mm vertically.
