Performance evaluation of GNSS kinematic PPP and PPP-IAR in structural health monitoring of bridge: Case studies

•Validated kinematic PPP and PPP-IAR positioning performance in regional network stations and simulated displacement experiment.•Studied the displacement and vibration monitoring performance using kinematic PPP and PPP-IAR in different bridge monitoring cases.•PPP and PPP-IAR can effectively identify bridge vertical deformation caused by vehicle loading.•PPP-IAR has faster convergence speed and higher accuracy than PPP solutions.
