This paper demonstrates the factors which influence the GPS PPP accuracy and selects a large number of data to get the PPP accuracy level.The results show that the level of accuracy of the PPP technology can be used to direct orientation of small-scale mapping and the PPP accuracy is limited by the precise ephemeris accuracy level and software algorithms.
