PSInSAR™ is an efficient tool for high precision monitoring of deformation of the Earth's surface and is based on the use of a time series of satellite radar images. Italferr has recently signed a Framework Agreement with the company owning the exclusive patent of the PSInSAR™ technique thus opening the way to a series of applications in the railway field; these applications could be a useful support in all life phases of the infrastructure: from the design phase to the construction and operation phases. This paper describes the satellite image processing technique revealing its limits and its potentials: a particular potential is the availability of a satellite image historical archive all over the nation thus allowing the recovery displacement historic time series dating back up to 1992. Some possible applications in the railway field are then analyzed with particular reference to case studies involving underground works (the Cassia-Monte Mario tunnel in Rome and the Scianina-Tracoccia tunnel in Messina). Recent analyses carried out in the area of the working sites of the Bologna Node, during work for the completion of the tunnel along the new High-Speed/High-Capacity line, provided a useful comparison between the displacement measurements obtained by satellite data processing and the topographic measurement data obtained during the work.
