Continuous monitoring of the structural health of strategic structures and transportation infrastructures is vital for accurately assessing safety conditions and effectively planning both routine and extraordinary maintenance. Key strategies adopted for this purpose include deformation tracking and the identification of dynamic characteristics. In recent years, one of the most significant advancements in structural health monitoring has been the use of satellite interferometry data. This technology offers valuable insight into structural deformations at both local and regional scales. Although satellite-based methods for monitoring ground deformations over time are generally reliable, their application to structural monitoring could present certain limitations. These issues are especially evident in structures that are sensitive to temperature variations. This study investigates these challenges through the case of the Ponte della Musica – Armando Trovajoli in Rome. The bridge, featuring a steel arch and a prestressed concrete deck, exemplifies the limits of differential satellite interferometry in detecting displacements that exceed the measurable range, depending on the wavelength employed. To address these limitations, the study proposes developing a three-dimensional digital twin of the bridge, calibrated using experimental environmental vibration data. This approach enables a more precise assessment of thermal deformations due to air temperature fluctuations and aims to establish a reliable correlation between the vertical displacements of the bridge deck and those captured by satellite observations.
