Joint segmentation of multiple GPS coordinate serie

Abstract : For the first time, a joint general segmentation procedure of multiple GPS coordinate series is proposed fornearby stations. It allows simultaneously estimating station-specific trends, seasonal signals and a common groundmotion signal between series from adjacent stations. An extension of the model and the estimation procedure, which isan iterative procedure, proposed following Picard et al. (2011) and Bertin et al. (2014) is considered in order to takeinto account for the specificities of the GPS data. The tested approach has been shown to be efficient in providingmeaningful offsets and is found to be a relevant method for avoiding segmenting the true physical signal.
