Abstract
In order to improve kinematic single epoch positioning accuracy and realize real-time pro-cessing,the article presents a precise kinematic single epoch positioning algorithm using moving win-dow wavelet denoising.Firstly,we obtain the observation residuals by using the conventional singleepoch method and improve end effect by data extending apart of the current epoch.Secondly,wedenoise the current epoch observation residuals using a window wavelet,and achieve an adaptive selec-tion of the wavelet decomposition level for denoising through cross-validation.Finally,we achieve fi-nal positioning accuracy using the clean observations,after denosing.Comparing the proposed methodwith conventional single epoch positioning,experimental results show that positioning accuracy hasbeen improved greatly for different motions.The results were consistent with those from wavelet postprocessing.
