Shuqiang Xue · Engineering of Surveying and Mapping · 2011
The divergence of GPS single frequency phase-smoothed pseudorange is theoretically analyzed,which is based on Hatch-type filtering for carrier phase smoothing.Then the subsection smoothing method based on sliding window is given.Using the self-developed software,the verification of the divergence of GPS single frequency phase-smoothed pseudorange is done with the data set from IGS tracking station.The feasibility and availability of this method are analyzed in the end.The results show that the divergence of single frequency phase-smoothed pseudorange can be better controlled,and then the phase-smoothed effectiveness is ensured.
