“…The main elements of a generic GNSS receiver are an antenna and a microprocessor which allow for analysing the information contained in the GNSS signal and obtaining the position of the antenna phase centre in a geocentric reference system (i.e., for GPS, in the WGS84 reference system). GNSS signals can be processed and analysed in several ways with different levels of accuracy [19]. In the last decade, also dynamic applications and deflection monitoring of large structures have been proposed [19].…”

In the last decade, also dynamic applications and deflection monitoring of large structures have been proposed [19]. Nowadays, the static methods based on Differential-GNSS strategies allow for a high-precision positioning providing coordinates of ground locations with millimetric precision, both in the horizontal and in the vertical components [20].…”

Structural health monitoring (SHM) can support decision makers in structural integrity management by providing information about occurrence of damage and its evolution in time. Recently, due to new Synthetic Aperture Radar (SAR) missions, remote sensing through active satellites provides a promising methodology capable of monitoring infrastructure assets. This paper investigates the use of Multi‐Temporal Synthetic Aperture Radar Interferometry (MT‐InSAR) processing to monitor the structural health of bridges. The full interferometry processing chain is applied using Sentinel‐1 synthetic aperture radar data and a combination of open‐source routines from the Sentinel Application Platform (SNAP) and Stanford Method for Persistent Scatterers (StaMPS). Displacement time‐histories are derived from single look complex products by employing the Persistent Scatterer Interferometry (PSInSAR) technique. The PS‐InSAR technique is applied to study the behavior of a concrete bridge located over the Oglio river in Isola Dovarese, Italy, on which also GNSS receivers are installed. The GNSS data are then used to validate the PS‐InSAR measurements. The effects on PS‐InSAR results of the number of SAR images used as well of the target structure are investigated.

Summary Global Navigation Satellite System (GNSS) positioning technology has had widespread applications in the structural health monitoring as its overall performance has improved significantly in the last two decades. It is capable of providing timely and accurate structural vibration information such as dynamic displacements and modal frequencies at higher performance than traditional accelerometers. The studies summarized in this paper focus on the improvement of the multi‐sensors and multi‐constellation data acquisition techniques, the improvement of multiple approaches for erroneous noise mitigation, and innovative modal parameter identification methods. We also detailed the applications of GNSS on the deformation monitoring for towers, chimneys, tall buildings, and bridges. With continuous enhancements in the algorithm and hardware of GNSS, it is expected that the application of GNSS technology can be expanded to other fields such as bridge cable‐force measurements and bridge weight‐in‐motion as well as structural deformation monitoring.

“…The PPP using clock and orbit products automatically ties the resulting coordinates to the highly-accurate homogenous global International Terrestrial Reference Frame (ITRF2008). The strategy initially used by scientists studying the condition of ionosphere, the motion of continental plates, time transfer and tropospheric parameters estimation, has recently become popular for surveying, precise positioning and even in precision farming Bisnath, and Gao, 2009;Araszkiewicz et al, 2010, Kalita et al, 2014Roberts et al, 2015;Golaszewski et al, 2017, Paziewski et al, 2017. The reason for this is mainly the simplification of processing using PPP software packages or online automatic services calculating positions based on a submitted Receiver Independent Exchange System (RINEX) observation file.…”

ABSTRACT:In high-accuracy positioning using GNSS, the most common solution is still relative positioning using double-difference observations of dual-frequency measurements. An increasingly popular alternative to relative positioning are undifferenced approaches, which are designed to make full use of modern satellite systems and signals. Positions referenced to global International Terrestrial Reference Frame (ITRF2008) obtained from Precise Point Positioning (PPP) or Undifferenced (UD) network solutions have to be transformed to national (regional) reference frame, which introduces additional bases related to the transformation process.In this paper, satellite observations from two test networks using different observation time series were processed. The first test concerns the positioning accuracy from processing one year of dual-frequency GPS observations from 14 EUREF Permanent Network (EPN) stations using NAPEOS 3.3.1 software. The results were transformed into a national reference frame (PL-ETRF2000) and compared to positions from an EPN cumulative solution, which was adopted as the true coordinates. Daily observations were processed using PPP and UD multi-station solutions to determine the final accuracy resulting from satellite positioning, the transformation to national coordinate systems and Eurasian intraplate plate velocities. The second numerical test involved similar processing strategies of post-processing carried out using different observation time series (30 min., 1 hour, 2 hours, daily) and different classes of GNSS receivers. The centimeter accuracy of results presented in the national coordinate system satisfies the requirements of many surveying and engineering applications.
