Sidereal filtering based on single differences for mitigating GPS multipath effects on short baselines
TL;DR: Wavelet spectra have shown that the proposed sidereal filtering algorithm is more effective in mitigating multipath errors of both long and short periods and is applicable when different GPS satellites are observed on different days.
Journal ArticleDOI
Filtering GPS time-series using a Vondrak filter and cross-validation
TL;DR: A new data filtering method, based on the Vondrak filter and the technique of cross-validation, is developed for separating signals from noise in data series, and applied to mitigate GPS multipath effects in applications such as deformation monitoring.
Journal ArticleDOI
Adaptive wavelet transform based on cross-validation method and its application to GPS multipath mitigation
TL;DR: A multipath correction model is derived based on the proposed method and the sidereal day-to-day repeating property of GPS multipath signals to remove multipath effects on GPS observations and to improve the quality of the GPS measurements.
Journal ArticleDOI
Estimates of ocean tide loading displacements and its impact on position time series in Hong Kong using a dense continuous GPS network
TL;DR: In this paper, GPS-derived ocean tide loading (OTL) displacements of eight diurnal and semidiurnal constituents at 12 sites in Hong Kong were estimated using 3-7 years of continuous global positioning system (GPS) observations.
Journal ArticleDOI
Tight integration of GPS observations and persistent scatterer InSAR for detecting vertical ground motion in Hong Kong
TL;DR: A method for tightly integrating GPS observations and the persistent scatterer interferometric synthetic aperture radar (InSAR) is proposed to detect vertical ground motion in Hong Kong, China and the results show that the method is capable of detecting accurately the vertical groundmotion.
