Abstract: Compared with the tranditional psudo-range Common-View timing method,the advantage and the significance of the precise timing with Stand-along receiver have been explicitly exhibited in the first part of this paper.The theory and the mathematical model of single point carrier phase smoothed psudo-range timing is then proposed.In the following parts the author analyzes the difficulties of the techniques and gives the precise estimation method and its indicator.Finally,along with the practical programme served for the research,we test and demonstrate the Point Precise Phase smoothed Psudo-range timing with experiments.The results supports that the absolute timing precision of the method could be as high as ns level.
