Outline
Aiming at the problem that the static relative positioning technology has a long calculation cycle and cannot timely reflect abrupt deformations when using Beidou/GNSS technology for infrastructure deformation monitoring currently, this paper proposes a real-time fusion method for monitoring results of static and RTK with different time scales and positioning accuracies, based on wavelet decomposition and dynamic weighted fusion of sliding time windows. Through experimental tests in the ultra-short baseline field, it is verified that this method can provide millimeter-level monitoring accuracy results when the monitored object is stable or deforms slowly, and can timely output the actual displacement when abrupt deformation occurs, with accuracy superior to that of RTK monitoring results. The method can be implemented based on general-purpose GNSS data processing software available on the market, and has a good prospect of engineering application.
