“…They will always be to the east, west and south of the user. This will result in a north-south geometry inbalance, and hence more noise resulting in less precision and accuracy in this direction [Roberts et al, 2006]. Figure 10 illustrates the differential movements between locations C and E. There are obviously differential movements between these locations; however, the horizontal component is very small.…”

“…The authors' work started on the Humber Bridge [Ashkenazi et al, 1997], and then moved onto the Millennium Bridge in London [Roberts et al, 2006], the Wilford Bridge in Nottingham [Meo et al, 2004], the Forth Road Bridge , the Avonmouth M5 crossing and now the M48 Severn Suspension Bridge [Roberts et al, 2010]. Historically the authors have clamped the GPS/GNSS antennas onto the parapet on the side of the bridge, and on the parapets at the tops of the towers [e.g.…”

ABSTRACT:The Severn Bridge is a suspension bridge, in total 1,600m long with a main span of 988m and tower heights of 136m.In 2010, a series of field surveys were commissioned to monitor the magnitude and frequencies of the Severn Suspension Bridge's movements, through attaching 9 dual-frequency survey grade GNSS receivers on the Bridge, and two reference GNSS stations located adjacent to the structure. The bridge's GNSS receivers were attached to the tops of the two pairs of towers, as well as 5 GNSS antennas attached directly onto the suspension cables. Four were attached at various locations on the Northern cable, and one on the southern cable.

“…Robers and Meng, from the University of Nottingham, UK have been working on the GNSS study for bridge health monitoring for a long time since 2000 [63]. Their results were applied to the Wilford Suspension Bridge in Nottingham [64][65][66], the Forth Road Bridge in Scotland [67,68] and the Millennium Bridge on the Thames in London [69]. The results were encouraging.…”

Deformation monitoring and dynamic characteristic analysis of bridge structures are the vital and basic requirements for the safe operation of bridges. In recent years, Global Navigation Satellite System (GNSS) has become increasingly widely used in bridge structural health monitoring with the development of the GNSS technology, especially the continuous improvement and development of China's Beidou navigation satellite system (BDS). This article summarises the application process of GNSS dynamic deformation monitoring and the development of GNSS deformation measurement technology of bridge structural health monitoring, the dynamic characteristic identification method and its application in bridge GNSS monitoring. The positioning solution methods for GNSS monitoring, the high sampling rate GNSS receiver for monitoring, multi-frequency and multi-system GNSS monitoring and the weakening of multipath effect of GNSS monitoring are summarised in detail. Then, the conclusions and prospects are posed for future research and related application.

Examples of SHM deployments with anomaly detection components have been reported in Chang and Im (2000); ; Staquet et al (2007); Koo et al (2013); Roberts et al (2006Roberts et al ( , 2012; and Minardo et al (2012). Chandola et al (2009) give a detailed treatise on the fundamentals of detecting anomalies in data sets.…”

The findings of an extensive literature survey focusing on bridge structural health monitoring (SHM) deployments are presented. Conventional, maturing, and emerging technologies are reviewed as well as deployment considerations for new SHM endeavors. The lack of published calibration studies (and quantification of uncertainty studies) for new sensors is highlighted as a major concern and area for future research. There are currently very few examples of SHM systems that have clearly provided significant value to the owners of monitored structures. The results of the literature survey are used to propose a categorization system to better assess the potential outcomes of bridge SHM deployments. It is shown that SHM studies can be categorized as one (or a combination) of the following: (1) anomaly detection, (2) sensor deployment studies, (3) model validation, (4) threshold check, and (5) damage detection. The new framework aids engineers specifying monitoring systems to determine what should be measured and why, hence allowing them to better evaluate what value may be delivered to the relevant stakeholders for the monitoring investments.
