In Present,there is no consideration for GPS satellite clock interpolation error in the observation stochastic model in Precise Point Positioning.An improved stochastic model considering the satellite clock interpolation error has been proposed.Experiments shown that this model could reduce the satellite clock interpolation error dramatically for larger time interval clock product(e.g.5 min) while has little improvement for small time interval product(e.g.30 s).The result accords with the characteristic of GPS satellite clock interpolation error.
