“…The main advantage of the NRTK monitoring system is its low cost. While the correction base depends on the available global network for the country; therefore, the designed system used one receiver to collect the structure's data and solved it using a DGPS system [59]. The results of this study showed that the NRTK-GNSS can be used to detect the bridges dynamic behavior [59].…”

“…The filtering validity was assessed in comparison to the records of the accelerometer as far as the timing of the excitation is concerned: filtering is valid only when two independently defined intervals coincide. Similar approaches, though with different filters, have been proposed by various authors [16,59,71], but this approach allows an independent assessment of its validity, concerning the precise excitation intervals defined by the accelerometer record. Second, the frequencies have been identified dominating the spectrum of the displacement short-period component.…”

“…They reported that the results can push the limits of the application of GNSS in structural-health monitoring and identification to stiff structures, and it can be used to estimate the damping ratio up to 3.22 [16]. Finally, Yu et al [59] introduced a dynamic network-based real-time kinematic (NRTK) GNSS monitoring system of bridges. The main advantage of the NRTK monitoring system is its low cost.…”

“…As such, this can push the limits of the GNSS application to stiff structures monitoring and identification with natural frequencies of 6 Hz and movements of a few millimeters only, representing the majority of structures. Moreover, many studies used the 10 to 20 Hz sampling frequencies of the GPS monitoring systems applications for the different cases of structures performances evaluations [3,18,19,25,52,[55][56][57][58][59].…”

This paper presents the recent development in Structural Health Monitoring (SHM) applications for monitoring the dynamic behavior of structures using the Global Positioning Systems (GPS) technique. GPS monitoring systems for real-time kinematic (RTK), precise point positioning (PPP) and the sampling frequency development of GPS measurements are summarized for time series analysis. Recent proposed time series GPS monitoring systems, errors sources and mitigation, as well as system analysis and identification, are presented and discussed.

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 paper mainly reports the structural dynamic behaviors of a skyscraper under operational conditions based on a wireless distributed synchronized data acquisition (WDSA) system. First, the WDSA system is developed to conveniently acquire the structural responses from a large and complex structure with the unified Global Navigation Satellite System (GNSS) time information.The phase synchronization accuracy of the WDSA method is validated by comparing the modal parameters estimated by both wired central data acquisition (WCA) and the WDSA systems. Subsequently, the dynamic properties of a skyscraper are presented by performing operational modal analysis (OMA) based on the proposed WDSA system. Finally, the WDSA-based continuous dynamic monitoring system is further developed to capture the long-term structural responses at different spatial positions. The structural dynamic behaviors of the skyscraper under normal wind, typhoon and earthquake conditions are reported. The structural "whiplash effect" under both normal wind and earthquake conditions are characterized by the acceleration-based accumulated contribution factor.
