Abstract
Using the precise ephemeris and the precise satellite clock correction can realize the precise point positioning(PPP).The precise ephemeris and the precise satellite clock correction provided by the different analysis centers is inconsistent.Using the precise ephemeris and the precise satellite clock correction which the different analysis center provides have the influence to the precise point positioning.The precision influences of the surveying station coordinate is compared to use the IGS precise ephemeris,JPL precise ephemeris and the same IGS precise satellite clock correction respectively.
