Extracting white noise statistics in GPS coordinate time series

Montillet, Jean-Philippe; Tregoning, Paul; McClusky, Simon; Yu, Kegen


The noise in GPS coordinate time series is known to follow a power-law noise model with different components (white noise, flicker noise, and random walk). This work proposes an algorithm to estimate the white noise statistics, through the decomposition of the GPS coordinate time series into a sequence of sub time series using the empirical mode decomposition algorithm. The proposed algorithm estimates the Hurst parameter for each sub time series and then selects the sub time series related to...[Show more]
