GNSS/accelerometer integrated deformation monitoring algorithm based on sensors adaptive noise modeling

•Adaptive noise model based on GNSS and accelerometer sensors were proposed for Kalman filtering.•A quantitative inflated factor function based on STD was introduced to match the time-varying noise of accelerometers in real-time.•Deformation experiments in different states (static and dynamic, whether GNSS signal interference) were conducted to fully validate the contribution of the new algorithm.
