This paper presents a study on a GNSS based Structural Health Monitoring (SHM) system, exploiting advanced PPP technologies, with sampling frequency up to 50 Hz. The work is framed in the activities of the EU H2020 project GISCAD-OV and it aims to develop an RTK GPS and Galileo High Accuracy positioning System (G-HAS) that can be used as an SHM system for civil structures, in comparison with more traditional accelerometric systems. The methodology consisted of the monitoring of a benchmark structure by means of both the G-HAS and an accelerometric system installed by the Italian Department of Civil Protection (DPC). The comparison between the results was carried out in the time and frequency domain. The time domain comparison was conducted by means of the acquired real-time displacements, while the frequency domain analysis was developed by means of the principal vibration frequency. The main goal of the paper is to demonstrate the accuracy of the G-HAS as an SHM system in both the time and frequency domain, paving the way for the development of an affordable and efficient large-scale SHM tool.

Abstract
This paper presents a study on a GNSS based Structural Health Monitoring (SHM) system, exploiting advanced PPP technologies, with sampling frequency up to 50 Hz. The work is framed in the activities of the EU H2020 project GISCAD-OV and it aims to develop an RTK GPS and Galileo High Accuracy positioning System (G-HAS) that can be used as an SHM system for civil structures, in comparison with more traditional accelerometric systems. The methodology consisted of the monitoring of a benchmark structure by means of both the G-HAS and an accelerometric system installed by the Italian Department of Civil Protection (DPC). The comparison between the results was carried out in the time and frequency domain. The time domain comparison was conducted by means of the acquired real-time displacements, while the frequency domain analysis was developed by means of the principal vibration frequency. The main goal of the paper is to demonstrate the accuracy of the G-HAS as an SHM system in both the time and frequency domain, paving the way for the development of an affordable and efficient large-scale SHM tool.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
