In this paper,GPS single frequency phase-smoothed pseudorange based on Hatch-type filter and it's point positioning were researched.Taking into account the divergence of GPS single frequency phase-smoothed pseudorange,the subsection smoothing method based on sliding window was given and the software modules were developed.Using the self-developed software and utilizing the static state to simulate dynamic,the single frequency pseudorange was smoothed with phase and the dynamic point positioning computations were carried out with the data set from IGS tracking station,and the respective accuracies were analyzed.With the results,the feasibility and effectiveness of this method were verified finally.
