Detecting Offsets in GPS Coordinate Time Series Based on SSA Method
Abstract Detecting possible offsets is a key step in GPS coordinate time series preprocessing, and automatic detection of offsets is necessary for the management of dense or large GPS networks. Using real coordinate time series, we propose a new idea of automatic offset detection based on SSA, and verify the effectiveness of the method. The results show that the SSA-based method can successfully detect the offsets with obvious steps; transient motion such as postseismic deformation does not affect the detection results; however, in the case where the difference between the offsets and background motion is not obvious, this method is subject to certain limitations.
