The global positioning system (GPS) of navigation satellites can now be used for real-time monitoring of large-scale structures, such as reservoirs,tall buildings and bridges. This paper describes the way in which the UK’s Humber bridge was monitored using ‘kinematic GPS’. The results show remarkable accuracies of the order of a few millimetres in all three directions. They demonstrate that the technique allows the collection of real-time deflection data which could be used to determine the deformation characteristics of the bridge and eventually provide a structural failure alarm capability.
