The utilization of RTK-GPS for real-time structural health detection

As safety precautions, the need for rapid assessment of the state of large engineering structure after extreme events such as earthquake, tsunami, typhoon or related wind effects is highly demanded. Compared to other often used practices such as acceleration integration method, laser distance gauge...
