40th IABSE Symposium : Tomorrow's Megastructures, NANTES, FRANCE, 19-/09/2018 - 21/09/2018; Global Positioning System (GPS) is a satellite constellation allowing positioning in a constantly updated global reference frame for almost any user on the globe. Over the last decade, GPS has been expanded to Global Navigation Satellite Systems (GNSS) with the progressive addition of three satellite constellations. This evolution enables a more robust and effective positioning calculation, thus improving the performance and reliability of GNSS-based monitoring systems. In parallel, improvements in GNSS receivers provide higher frequency and precision calculations, with shorter computation time, enabling GNSS techniques to be used both for long-term monitoring of slow displacements, and for the analysis of short term events. This paper explores the performances and possibilities of low-cost GNSS receivers in order to improve structural health monitoring systems of large and flexible structures such as bridges, towers or cooling-towers. Low-cost carrier-phase receivers, coupled with various processing methods and parameters, are evaluated to the extent of characterizing both long term precision and stability, and qualification of short displacements and oscillations. The amplitudes and frequencies of displacements and oscillations tested are selected in accordance with phenomena that may be observed on flexible structures. The use of a high-quality reference station with very short baseline is proven a good alternative over expensive receiver upgrading, with rovers able to qualify abrupt displacements down to 4mm, and accurately monitor oscillations with frequencies up to 0.25Hz and amplitudes down to 1cm with a 1Hz sampling rate. Data acquired from a low-cost receiver installed on the main span of suspended bridge is evaluated in order to highlight quality and reliability of on-site applications, and was found highly correlated to traditional sensors data (resistance temperature detectors, and displacement laser sensors).

9th European Workshop on Structural Health Monitoring Series (EWSHM), MANCHESTER, ROYAUME-UNI, 10-/07/2018 - 13/07/2018; Over the last decade, the rapid expansion of Global Navigation Satellite Systems (GNSS) coupled with the incremental improvements on the existing GPS constellation has continuously increased the robustness of satellite positioning, therefore significantly improving the reliability and the possibilities of a GNSS-based structural health monitoring system. Moreover, thanks to constant evolution, GPS-only receivers have proven to be more and more efficient with relatively simple hardware, provided that they are used in an appropriate workflow such as relative positioning with short baselines. This paper presents an application of a network of cost-effective GPS receivers as a part of a monitoring system. Monitoring data are acquired from a network of a dozen of GPS 'Geocube' stations installed on a suspended bridge, the Brotonne Bridge, in France. One main objective of this network is to be able to detect some changes in bridge behaviour. Data from GPS sensor is analysed and correlated with traditional data, such as piers temperature. This study validates that a GPS sensor network can provide useful and reliable data for structural monitoring.
