ABSTRACT

As the number of bridges increases, the demand for bridge health monitoring is increasing year by year. With the progress of modern monitoring technology, the precision and efficiency of bridge monitoring have also been improved. There are many methods of bridge health monitoring with different characteristics, advantages, and disadvantages. However, with the development of information technology and satellite technology, Global Positioning System (GPS) monitoring appears to have more advantages, especially for the long-span Bridges. This paper mainly analyzes the components of GPS and the working principle of GPS monitoring. Meanwhile, it demonstrates that GPS monitoring methods have advantages of high frequency, all-weather and dynamic visualization of monitoring data by comparing with other monitoring methods. Finally, the paper analyzes the limitation of GPS monitoring and problems to be solved by a simple forecast of its future development.
