%X Aiming at the accuracy of the GPS satellite clock bias service the real-time precise point positioning(PPP) currently,a method for real-time estimating the satellite clock bias based on the basis of IGU(IGS Ultra-rapid) predicted orbits is put forward.In this method the un-differenced carrier phase observations of global reference stations is used to estimate the real-time clock bias.Numerical calculation results show that most of deviations between the estimated satellite clock bias and the IGS final produ...
