Abstract: Objectives:In order to effectively extract useful information from time series of the global navigation satellite system（GNSS） sites, and improve the modeling accuracy of coordinate time series, this paper proposes a nonlinear motion modeling method combining wavelet decomposition and singular spectrum analysis. Experiments were carried out using global positioning system（GPS） vertical coordinate time series of 11 stations around the world from 1999 to 2018. Methods: Firstly, the coordinate time... More
