The algorithm of smoothing pseudo-range with carrier phase and its application to the dual ranging and time synchronization(DRTS) system are introduced. The calculation and analyses of the measured data show that the application of the algorithm of smoothing pseudo-range with carrier phase to the DRTS can improve the ranging accuracy of DRTS. The processing methods for the pseudo-code mistakes and carrier phase leaps which occurred during the measurements are also given in this paper, and the simulation and analyses show that these methods can reduce the error caused by the pseudo-code mistakes and carrier phase leaps.
