Abstract

Multipath mitigation techniques using wavelet decomposition is proposed for extracting or modelling multipath from Global Positioning System (GPS) carrier phase observations. Multipath can be reduced by choosing sites without multipath reflectors or by using choke-ring antennas to mitigate the reflected signal. In this paper, we apply a method based on wavelets to decompose GPS doubledifferenced (DD) residuals into a low-frequency bias term and a high-frequency noise term to extract multipath from GPS observation. Wavelet transform (WT) is a new tool for signal analysis that can provide time and frequency information of a signal sequence simultaneously. The results show that the proposed method can be used to significantly mitigate the multipath effects at GPS data.
